Definitions

  • the present invention relates to inter alia, polynucleotides and methods of use thereof and in particular to cotton plants comprising said polynucleotides.
  • the invention relates to a cotton event designated CE44-69D which comprises a Cry IAb gene.
  • the invention also relates to methods of identifying specific cotton events which contain a gene capable of conferring insect resistance on said cotton plants.
  • Plant pests are a major factor in the loss of the world's important agricultural crops. About $8 billion is lost every year in the U.S. due to infestations of plants by non-mammalian pests including insects. In addition to losses in field crops, insect pests are also a burden to vegetable and fruit growers, to producers of ornamental flowers, and to home gardeners.
  • Insect pests are mainly controlled by intensive applications of chemical pesticides, which are active through inhibition of insect growth, prevention of insect feeding or reproduction, or cause death. Good control of insect pests can thus be reached, but these chemicals can sometimes also affect other, beneficial insects.
  • Another problem resulting from the wide use of chemical pesticides is the appearance of resistant insect varieties. This has been partially alleviated by various resistance management practices, but there is an increasing need for alternative pest control agents.
  • Biological pest control agents such as Bacillus thuringiensis strains expressing pesticidal toxins like ⁇ -endotoxins, have also been applied to crop plants with satisfactory results, offering an alternative or compliment to chemical pesticides.
  • Cry IAc is one of a large family of insecticidal toxins produced by different strains of Bacillus thuringiensis. Each toxin in the family has a unique spectrum of insecticidal activity.
  • the cotton family genus Gossypium, a member of the Malvaceae, consists of 39 species, of which Gossypium hirsutum is the most commonly cultivated species. Three other species are also cultivated: G. arboreum, G. barbadense, and G. herbaceum. These cultivated species are grown primarily for the seed hairs that are made into textiles. Cotton is suitable as a textile fibre because the mature dry hairs twist in such a way that fine strong threads can be spun from them. Other products, such as cottonseed oil, cake, and cotton linters are by-products of fibre production.
  • insect pests of cotton include Beet armyworm (Spodoptera exigua), Boll weevil (Anthonomus grandis grandis), Cabbage looper (Trichoplusia ni), Clouded plant bug (Neurocolpus nubilus), Cotton aphid (Aphis gossypii), Cotton bollworm (Heliocoverpa zed), Cutworms (Feltia subterranea, Peridroma saucia, Agrotis ipsilon), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperd ⁇ ), Pink boll worm (Pectinophera gossypielld), Seedling thrips (Frankliniella spp.), Soybean looper (Pseudoplusia includens), St
  • Transformation and regeneration of cotton plants is now a well-established procedure, typically based on Agrobacterium tumefaciens mediated transfer of foreign DNA into cotton plant parts and regeneration of said plant parts in tissue culture into fully fertile, transgenic cotton plants.
  • the present invention provides, inter alia, a specific cotton event (referred to hereinafter as "CE44-69D") and methods for the identification thereof.
  • This specific event has been selected based on, inter alia, its agronomic performance, efficacy and molecular characteristics. It is believed that the characteristics of this event are far superior to like transformants based upon, inter alia, the integration site of the transgene during the transformation process.
  • CE44-69D event in the context of this application refers to the original insecticidal transgenic cotton plant described herein and any plant material derived therefrom, including seeds.
  • Insecticidal refers to any inhibitory effect on an insect, including but not limited to reduced feeding, retarded growth, reduced fecundity, paralysis or death.
  • Flucundity comprises all aspects related to reproduction such as reproductive ability, reproductive frequency and number of offspring.
  • Also embraced by this invention is any plant material derived from the CE44-69D event, including seeds.
  • the CE44-69D event exhibits a novel genotype comprising at least one expression cassette.
  • the cassette comprises a suitable promoter for expression in plants operably linked to a gene that encodes a Cryl Ab insecticidal toxin, useful in controlling a wide spectrum of lepidopteran insect pests, and a suitable polyadenylation signal.
  • Suitable promoters may be isolated from, inter alia, plants. Numerous plant promoters have been isolated and characterised including constitutive, switchable and/or tissue specific promoters.
  • Suitable promoters may be selected from the following, non-limiting group: CaMV35S, FMV35S, Ubiquitin, Act2, NOS, OCS, Cestrum yellow leaf curl virus promoter, Patatin, E9, alcA/alcR switch, GST switch, RMS switch, oleosin, Gelvin, ribulose bisphosphate carboxylase-oxygenase small sub-unit, actin 7, MR7 promoter (maize), Gos 9 (rice), GOS2 promoters, MasOcs (or super promoter), RoID promoter (Agrobacterium rhizogenes), SuperMAS promoter, and Suc2 promoter (Arabidopsis).
  • the promoter is the Actin promoter, ACT2, from Arabidopsis thaliana. Additional elements such as enhancer sequences may also be incorporated into the expression cassette in order to boost levels of gene expression, for example transcriptional or translational enhancers, such as tobacco etch virus (TEV) translation activator, CaMV35S enhancer, and FMV35S enhancer. Alternatively it may be desirable to include a targeting sequence, for example, to direct transportation of the Cryl Ab toxin to a particular cellular compartment. For example, if it is desired to provide the protein outside of the cell then an extracellular targeting sequence may be ligated to the polynucleotide encoding the Cry IAb protein.
  • TMV tobacco etch virus
  • targeting include targeting to a specific intracellular organelle or compartment, for example to the endoplasmic reticulum using a 'KDEL' retention sequence.
  • Numerous polyadenylation signals have been isolated and characterised. Examples of suitable polyadenylation signals functional in plants include that from the nopaline synthase gene (nos) of Agrobacterium tumefaciens, from the proteinase inhibitor II gene and from the alpha-tubulin gene (EP-A 652,286). In one embodiment of the present invention, the polyadenylation signal is that from the nos gene of Agrobacterium tumefaciens.
  • the polynucleotide encoding the Cry IAb protein may be codon-optimised or otherwise altered to enhance for example, translation once it is incorporated into plant material.
  • codon optimisation may also be used to alter the predicted secondary structure of the RNA transcript produced in any transformed cell, or to destroy cryptic RNA instability elements present in the unaltered transcript, thereby increasing the stability and/or availability of the transcript in the transformed cell (Abler and Green (1996) Plant Molecular Biology (32) pp.63-78). Codon optimisation may also be employed to alter a heterologous DNA coding sequence so that it more closely resembles the coding sequence of a gene of the host.
  • a bacterial gene can be codon optimised to increase the ratio of cytosine and guanine bases to adenine and thymine bases so that it more closely resembles a plant (e.g. cotton or maize) gene, yet encodes the same protein.
  • codon optimisation may be performed in accordance with standard codon usage tables.
  • a second cassette is present that comprises a gene which, when expressed, can be used as a selectable marker.
  • selectable markers Numerous selectable markers have been characterised, including some that confer tolerance to antibiotics and others that confer tolerance to herbicides. Examples of suitable selectable marker genes include those that confer tolerance to hygromycin, kanamycin or gentamycin. Further suitable selectable markers include genes that confer resistance to herbicides such as glyphosate-based herbicides or resistance to toxins such as eutypine. Other forms of selection are also available such as hormone based selection systems such as the Multi Auto Transformation (MAT) system of Hiroyrasu Ebinuma et al. (1997) PNAS Vol.
  • MAT Multi Auto Transformation
  • the selectable marker gene is one that confers tolerance to hygromycin.
  • This second expression cassette is useful for selecting transformants during and following plant transformation. Optionally, it may be segregated away from the CE44-69D event precursor after transformation to leave the CE44-69D event itself.
  • the CE44-69D event per se does not comprise a selectable marker cassette.
  • Further expression cassettes are optionally comprised in the CE44-69D event. For example these may provide genes encoding different insecticidal toxins such as VIP3A. Alternatively, these may provide other desirable benefits such as herbicide resistance.

If the expression cassettes are present on the same plasmid and introduced into the plant via an Agrobacterium-mediated transformation method, they may be present within the same or different T-DNA regions.

Abstract

The present application relates an insect resistant transgenic cotton plant. In particular, it relates to a specific event, designated CE44-69D.

Description

CE44-69D INSECTICIDAL COTTON
The present invention relates to inter alia, polynucleotides and methods of use thereof and in particular to cotton plants comprising said polynucleotides. Specifically, the invention relates to a cotton event designated CE44-69D which comprises a Cry IAb gene. The invention also relates to methods of identifying specific cotton events which contain a gene capable of conferring insect resistance on said cotton plants.
Plant pests are a major factor in the loss of the world's important agricultural crops. About $8 billion is lost every year in the U.S. due to infestations of plants by non-mammalian pests including insects. In addition to losses in field crops, insect pests are also a burden to vegetable and fruit growers, to producers of ornamental flowers, and to home gardeners.
Insect pests are mainly controlled by intensive applications of chemical pesticides, which are active through inhibition of insect growth, prevention of insect feeding or reproduction, or cause death. Good control of insect pests can thus be reached, but these chemicals can sometimes also affect other, beneficial insects. Another problem resulting from the wide use of chemical pesticides is the appearance of resistant insect varieties. This has been partially alleviated by various resistance management practices, but there is an increasing need for alternative pest control agents. Biological pest control agents, such as Bacillus thuringiensis strains expressing pesticidal toxins like δ-endotoxins, have also been applied to crop plants with satisfactory results, offering an alternative or compliment to chemical pesticides. The genes coding for some of these δ-endotoxins have been isolated and their expression in heterologous hosts has been shown to provide another tool for the control of economically important insect pests. In particular, the expression of the insecticidal toxin Cry IAc from Bacillus thuringiensis in transgenic plants, has provided efficient protection against selected insect pests, and transgenic plants expressing this toxin have been commercialised, allowing farmers to reduce applications of chemical insect control agents. Cry IAc is one of a large family of insecticidal toxins produced by different strains of Bacillus thuringiensis. Each toxin in the family has a unique spectrum of insecticidal activity. The cotton family, genus Gossypium, a member of the Malvaceae, consists of 39 species, of which Gossypium hirsutum is the most commonly cultivated species. Three other species are also cultivated: G. arboreum, G. barbadense, and G. herbaceum. These cultivated species are grown primarily for the seed hairs that are made into textiles. Cotton is suitable as a textile fibre because the mature dry hairs twist in such a way that fine strong threads can be spun from them. Other products, such as cottonseed oil, cake, and cotton linters are by-products of fibre production.
Damage to cotton crops by insect pests throughout the world results in a significant yield loss each year. Effective control of these pests to minimise yield loss is of great economic importance. Examples of insect pests of cotton include Beet armyworm (Spodoptera exigua), Boll weevil (Anthonomus grandis grandis), Cabbage looper (Trichoplusia ni), Clouded plant bug (Neurocolpus nubilus), Cotton aphid (Aphis gossypii), Cotton bollworm (Heliocoverpa zed), Cutworms (Feltia subterranea, Peridroma saucia, Agrotis ipsilon), European corn borer (Ostrinia nubilalis), Fall armyworm (Spodoptera frugiperdά), Pink boll worm (Pectinophera gossypielld), Seedling thrips (Frankliniella spp.), Soybean looper (Pseudoplusia includens), Stink bugs (Nezara viridula, Acrosternum hilare, Euschistus servus), Tarnished plant bug (Lygus lineolaris), Tobacco budworm (Heliothis virescens) and Whiteflies (Trialeurodes abutilonea, Bemisia tabacϊ).
Transformation and regeneration of cotton plants is now a well-established procedure, typically based on Agrobacterium tumefaciens mediated transfer of foreign DNA into cotton plant parts and regeneration of said plant parts in tissue culture into fully fertile, transgenic cotton plants.
There exists a requirement to generate a new cotton plant that is insect resistant so that yield loss through damage to cotton crops by insect pests is reduced. An insect resistant cotton plant could reduce the need to apply chemical pesticides, which may be detrimental to other, beneficial insects and the environment. In particular, it is desirable to provide an alternative insect resistant plant to transgenic plants comprising the Cry IAc gene from Bacillus thuringiensis. The present invention provides, inter alia, a specific cotton event (referred to hereinafter as "CE44-69D") and methods for the identification thereof. This specific event has been selected based on, inter alia, its agronomic performance, efficacy and molecular characteristics. It is believed that the characteristics of this event are far superior to like transformants based upon, inter alia, the integration site of the transgene during the transformation process.
"CE44-69D event" in the context of this application refers to the original insecticidal transgenic cotton plant described herein and any plant material derived therefrom, including seeds. "Insecticidal" as used herein refers to any inhibitory effect on an insect, including but not limited to reduced feeding, retarded growth, reduced fecundity, paralysis or death. "Fecundity" comprises all aspects related to reproduction such as reproductive ability, reproductive frequency and number of offspring. Also embraced by this invention is any plant material derived from the CE44-69D event, including seeds.
The CE44-69D event exhibits a novel genotype comprising at least one expression cassette. The cassette comprises a suitable promoter for expression in plants operably linked to a gene that encodes a Cryl Ab insecticidal toxin, useful in controlling a wide spectrum of lepidopteran insect pests, and a suitable polyadenylation signal. Suitable promoters may be isolated from, inter alia, plants. Numerous plant promoters have been isolated and characterised including constitutive, switchable and/or tissue specific promoters. Suitable promoters may be selected from the following, non-limiting group: CaMV35S, FMV35S, Ubiquitin, Act2, NOS, OCS, Cestrum yellow leaf curl virus promoter, Patatin, E9, alcA/alcR switch, GST switch, RMS switch, oleosin, Gelvin, ribulose bisphosphate carboxylase-oxygenase small sub-unit, actin 7, MR7 promoter (maize), Gos 9 (rice), GOS2 promoters, MasOcs (or super promoter), RoID promoter (Agrobacterium rhizogenes), SuperMAS promoter, and Suc2 promoter (Arabidopsis). In one embodiment of the present invention, the promoter is the Actin promoter, ACT2, from Arabidopsis thaliana. Additional elements such as enhancer sequences may also be incorporated into the expression cassette in order to boost levels of gene expression, for example transcriptional or translational enhancers, such as tobacco etch virus (TEV) translation activator, CaMV35S enhancer, and FMV35S enhancer. Alternatively it may be desirable to include a targeting sequence, for example, to direct transportation of the Cryl Ab toxin to a particular cellular compartment. For example, if it is desired to provide the protein outside of the cell then an extracellular targeting sequence may be ligated to the polynucleotide encoding the Cry IAb protein. Other examples of targeting include targeting to a specific intracellular organelle or compartment, for example to the endoplasmic reticulum using a 'KDEL' retention sequence. Numerous polyadenylation signals have been isolated and characterised. Examples of suitable polyadenylation signals functional in plants include that from the nopaline synthase gene (nos) of Agrobacterium tumefaciens, from the proteinase inhibitor II gene and from the alpha-tubulin gene (EP-A 652,286). In one embodiment of the present invention, the polyadenylation signal is that from the nos gene of Agrobacterium tumefaciens.
The polynucleotide encoding the Cry IAb protein may be codon-optimised or otherwise altered to enhance for example, translation once it is incorporated into plant material. Such codon optimisation may also be used to alter the predicted secondary structure of the RNA transcript produced in any transformed cell, or to destroy cryptic RNA instability elements present in the unaltered transcript, thereby increasing the stability and/or availability of the transcript in the transformed cell (Abler and Green (1996) Plant Molecular Biology (32) pp.63-78). Codon optimisation may also be employed to alter a heterologous DNA coding sequence so that it more closely resembles the coding sequence of a gene of the host. For example, a bacterial gene can be codon optimised to increase the ratio of cytosine and guanine bases to adenine and thymine bases so that it more closely resembles a plant (e.g. cotton or maize) gene, yet encodes the same protein. Such codon optimisation may be performed in accordance with standard codon usage tables.
In a precursor to the CE44-69D event, a second cassette is present that comprises a gene which, when expressed, can be used as a selectable marker. Numerous selectable markers have been characterised, including some that confer tolerance to antibiotics and others that confer tolerance to herbicides. Examples of suitable selectable marker genes include those that confer tolerance to hygromycin, kanamycin or gentamycin. Further suitable selectable markers include genes that confer resistance to herbicides such as glyphosate-based herbicides or resistance to toxins such as eutypine. Other forms of selection are also available such as hormone based selection systems such as the Multi Auto Transformation (MAT) system of Hiroyrasu Ebinuma et al. (1997) PNAS Vol. 94 pp.21 17-2121 ; visual selection systems which use the known green fluorescence protein, β glucoronidase; and any other selection system such as mannose isomerase (Positech™), xylose isomerase and 2-deoxyglucose (2-DOG). In one embodiment of the present invention, the selectable marker gene is one that confers tolerance to hygromycin. This second expression cassette is useful for selecting transformants during and following plant transformation. Optionally, it may be segregated away from the CE44-69D event precursor after transformation to leave the CE44-69D event itself. The CE44-69D event per se does not comprise a selectable marker cassette. Further expression cassettes are optionally comprised in the CE44-69D event. For example these may provide genes encoding different insecticidal toxins such as VIP3A. Alternatively, these may provide other desirable benefits such as herbicide resistance.
The expression cassettes may be introduced into the plant on the same or different plasmids. If the expression cassettes are present on the same plasmid and introduced into the plant via an Agrobacterium-mediated transformation method, they may be present within the same or different T-DNA regions. In one embodiment of the present invention, two expression cassettes are present on different T-DNA regions within different plasmids.

In another embodiment, said second expression cassette encodes a protein that provides resistance to a herbicide which comprises glyphosate acid or an agriculturally acceptable salt thereof.
The skilled man is familiar with plant transformation methods. In particular, two principal techniques have been characterised across a wide range of plant species: transformation by Agro bacterium and transformation by direct DNA transfer.
Agrobacteriwn-mediated transformation is a commonly used method for transformation of dicotyledonous plants. The foreign DNA to be introduced into the plant is cloned into a binary vector in between left and right border consensus sequences. This is the T-DNA region. The binary vector is transferred into an Agrobacterium cell, which is subsequently used to infect plant tissue. The T-DNA region of the vector comprising the foreign DNA is inserted into the plant genome. The marker gene cassette and trait gene cassette may be present on the same T-DNA region, different T-DNA regions in the same vector, or even different T-DNA regions in different vectors. In one embodiment of the present invention, the cassettes are present on different T-DNA regions on different vectors.
Alternatively, direct DNA transfer can be used to introduce the DNA directly into a plant cell. One suitable method of direct transfer may be bombardment of plant cells with a vector comprising the DNA for insertion using a particle gun (particle-mediated biolistic transformation); another established method, 'whiskers', involves coating the DNA onto silicon carbide fibres onto which cells are impaled. Other methods for transforming plant cells include protoplast transformation (optionally in the presence of polyethylene glycols); sonication of plant tissues, cells or protoplasts in a medium comprising the polynucleotide or vector; micro-insertion of the polynucleotide or vector into plant material (optionally employing the known silicon carbide "whiskers" technique), electroporation and the like.
Following transformation, transgenic plants are regenerated from the transformed plant tissue, and progeny possessing the foreign DNA selected using an appropriate marker such as resistance to hygromycin. The skilled man is familiar with the composition of suitable regeneration media. The selectable marker can be segregated away from transgenic events by conventional plant breeding methods, thus resulting in, for example, the CE44-69D event.
A plant of the invention, as described herein, has an insecticidal effect on insects from one or more species from the group comprising Heliothis sp. and Helicoverpa sp. which may infest it. "Infest" as used herein refers to attack, colonisation, feeding or damage in any way by one or more insects. Thus, for example, the plant of the present invention will provide a self-defence mechanism against infestation by pest insects such as Helicoverpa zea (cotton boll worm). As a result, a reduced number of insecticide sprays are required during the cultivation of said plant compared to a non-transgenic cotton plant of the same variety and yield loss through insect pests is kept at a minimal level.
The present invention is not limited to the CE44-69D event itself, but is further extended to include any plant material derived therefrom, including seeds in so far as they contain at least one of the present inventive polynucleotides. The present invention includes, but is not limited to plants that are derived from a breeding cross with the CE44-69D event or a derivative therefrom by conventional breeding or other methods. The invention also includes plant material derived from the CE44-69D event that may comprise additional, modified or fewer polynucleotide sequences compared to the CE44-69D event or exhibit other phenotypic characteristics. For example, it may be desirable to transform plant material derived from the CE44-69D event to generate a new event that possesses an additional trait, such as a second insect resistance gene. This process is known as gene stacking. The second insect resistance gene may encode, for example insecticidal lectins, insecticidal protease inhibitors and insecticidal proteins derived from species of the Bacillus thuringiensis, Xenorhabdus nematophilus, or Photorabdus luminescens. In one aspect, the second insect resistance gene encodes an insecticidal gene from Bacillus thuringiensis. Preferably, the second insect resistance gene encodes a VIP gene from the bacterium Bacillus thuringiensis, which VIP gene produces a toxin with a different mode of action or binding site in the insect gut to Cry IAb for the control of different insect species. The VIP gene may, for example, be VIP3A.
The present invention further provides plant material derived from the CE44-69D event which possesses an additional trait such as herbicide resistance, nematode resistance or fungal resistance. In one embodiment, said additional trait is herbicide resistance. The herbicide resistance trait may be provided, for example, by a herbicide degradation enzyme, or a target-site specific resistant enzyme. In a further embodiment, said herbicide resistance trait provides resistance to a herbicide which comprises glyphosate acid or an agriculturally acceptable salt thereof. In a further embodiment still, said herbicide resistance trait is provided by a gene encoding EPSP synthase or a mutant thereof.
The present invention further provides a method of controlling insects comprising providing the CE44-69D event or plant material derived from the CE44-69D event at a locus where said insects feed. The invention yet further provides a method of controlling insects comprising providing the CE44-69D event or plant material derived from the CE44-69D event at a locus where said insects feed, and applying other agrochemicals to said plant material such as herbicides, fungicides and other insecticidal compounds including other insecticidal proteins. Examples of possible insecticidal compounds include insecticidal lectins, insecticidal protease inhibitors and insecticidal proteins derived from species of the Bacillus thuήngiensis, Xenorhabdus nematophilus, or Photorabdus luminescens. Examples of possible chemicals include pyrethroids, carbamates, imidacloprid, organochlorines, and macromolecules such as spinosad, abamectin or emamectin.
The present invention further provides a method for detecting plant material which is derived from the CE44-69D event, said method comprising: (a) preparing a sample containing the genomic DNA of the plant material to be tested; (b) obtaining a pair of primers which are suitable for use in an amplification reaction to amplify a sequence selected from the group consisting of: (i) a sequence comprising at least 18 contiguous nucleotides of the sequence depicted as SEQ ID NO: 3 and the complement thereof and (ii) a sequence comprising at least 18 contiguous nucleotides of the sequence depicted as SEQ ID NO: 4 and the complement thereof; (c) adding said pair of primers to said sample and the means for performing an amplification reaction; (d) performing an amplification reaction; and (e) visualising the thus amplified sequence.
There are many amplification methods that may be used in accordance with the methods of the invention. The underlying principle, a known technique to those skilled in the art, is the polymerase chain reaction (PCR). The amplification product from a PCR reaction may be visualised by staining with ethidium bromide and excitation with UV light, typically after size separation using agarose gel electrophoresis. In a particular embodiment of the invention variations of the PCR principle such as TaqMan™ may be used. Such techniques involve labelling at least one of the primers involved in the amplification process with a fluorescent dye. When unbound, the primer adopts a conformation such that no fluorescence can be detected. However, when the primer is bound to a piece of DNA, the conformation changes and fluorescence can be detected. In this way, the amplification process can be monitored in real-time, the intensity of fluorescence corresponding directly to the level of amplification.
TaqMan™ analysis may be useful for example, for detecting the presence of the CE44- 69D event in a background of wild type cotton, or for detecting the adventitious presence of CE44-69D in other germplasm. Further embodiments of the present invention include, but are not limited to, RACE PCR. A further embodiment of the present invention involves the use of multiplex PCR for distinguishing between homozygous CE44-69D plant material and heterozygous CE44- 69D plant material. This is known to those skilled in the art as zygosity testing, and involves the use of three PCR primers which bind to specific parts of the cotton genome and / or inserted DNA. The presence or absence of each of two amplification products of particular sizes indicates whether the test sample is hemizygous or homozygous for CE44- 69D. Suitable primers for use in such a zygosity test are depicted as SEQ ID NOs 6, 8 and 9.

This method is useful for distinguishing between plants expressing Cry IAb, such as plants comprising CE44-69D, and plants not-expressing Cry IAb. • i y —
Suitable methods of detecting plant material derived from the event described herein which methods are based on said antibody binding include, but are not limited to Western Blots, Enzyme-Linked Immunosorbent Assays (ELISA) and SELDI mass spectrometry. The skilled person is familiar with these and further immunological techniques. Typical steps include incubating a sample with an antibody that binds to the said protein, washing to remove unbound antibody, and detecting whether the antibody has bound. Many such detection methods are based on enzymatic reactions - for example the antibody may be tagged with an enzyme such as horseradish peroxidase, and on application of a suitable substrate, a colour change detected. Suitable antibodies may be monoclonal or polyclonal.
The present disclosure also includes a method of detecting plant material derived from an event described herein said method comprising obtaining a sample for analysis; making a protein extract of the sample; providing a test strip or dipstick designed to detect the presence of a said protein present within the sample; incubating the test strip or dipstick with the sample; and detecting whether said protein is present.
This method may be an antibody-based detection method for the events referred to herein and uses test strips or dipsticks. Typical steps include incubating a test strip or dipstick with a sample and observing the presence or absence of coloured bands on the test strip or dipstick. The coloured bands are indicative of the presence of a protein in the sample. Such test strip or dipstick tests are usually protein specific, and may be used for rapid testing of samples in the field.
In one embodiment, the immunological method or dipstick utilises an antibody or antibodies, or fragment/fragments thereof, specific for the Cry IAb gene from Bacillus thuringiensis as encoded by SEQ ID NO: 7. Antibody fragments include, but are not limited to, Fab, modified Fab, diFab, Fab', F(ab')2 or FV fragment, immunoglobulin light chain or heavy chain monomer, single chain FV (scFV) or nanobody. The antibody or fragment thereof may be monoclonal or polyclonal. In a particular embodiment, the antibody is an antibody secreted by cell lines selected from the group consisting of DSM ACC2723 and DSM ACC2724 (both deposited on 12 May 2005 at Deutsche Sammlung von Mikroorganismen und Zellkulturen GmbH, Mascheroder Weg Ib, 38124 Braunschweig, Germany) or an antibody which is capable of inhibiting the binding to the _
Cry IAb of an antibody secreted by cell lines selected from the group consisting of DSM ACC2723 and DSM ACC2724. It is noted that methods for producing both monoclonal and polyclonal antibodies and fragments thereof are well known in the art.
Suitable test strips or dipsticks and materials for their use are described in PCT application WO 02/27322 and are, for example, lateral-flow immunostrips comprising a detection membrane of cellulose acetate, cellulose, nitrocellulose or nylon, supported on a plastic backing. Such an immunostrip may be produced using membranes and filters through which a liquid sample is drawn by capillary action. The protein in the sample reacts with the antibodies contained in the immunostrip as it moves the length of the strip and is captured at a line that becomes visible. Suitable means of detection are, for example, colloidal gold and coloured latex beads.
In a particular embodiment, a line of specific anti-Cry IAb antibody, as described above, is sprayed on a test strip, which is suitably made from nitrocelluose supported on a plastic backing. A reagent control line of anti-mouse antibody is sprayed in parallel above the first antibody line. The membrane is flanked on the top by an absorption pad and on the bottom by a pad containing dried colloidal gold labelled anti-Cry IAb antibody. In a preferred embodiment, the colloidal gold-labelled anti-Cry IAb antibody is different from the first antibody sprayed as the test line. In a particular embodiment, the colloidal gold- labelled anti-Cry IAb antibody is the antibody secreted by cell line DSM ACC2723 and the antibody sprayed at the test line is the antibody secreted by cell line DSM ACC2724 . A sample application pad flanks the colloidal gold pad. In use, the sample application pad is placed in a sample of extracted tissue or this sample is applied to the pad in another way, for example, by pipette. Any Cry IAb protein contained within the sample flows up the strip and becomes bound by the colloidal gold labelled-anti-Cryl Ab antibody. As it continues up the strip, the protein also becomes bound by the anti-Cry IAb antibody at the test line. Excess gold conjugate is captured at the reagent control line. In a positive test, that is, if Cryl Ab is present in the sample, a double red line appears: the lower line indicates the presence of Cryl Ab while the upper line is the control line signalling a properly working device.

In a still further embodiment, said kit of parts may comprise in the form of instructions one or more of the methods described above.
In a still further aspect there is provided a plant or seed according to the invention which is used in a method of breeding. For example, the plants may be used to transfer the trait which provides for insect resistance into a plant of the same genus but having a different background germplasm. Such breeding into a different germplasm may be desired if the plant is to be grown in under conditions where an alternative germplasm is favourable. Methods for breeding that can be used to transfer the trait into a different background germplasm are well known in the art.
In a still further aspect there is provided the use of a plant or seed according to the invention to generate explant material for use in a method of transformation of said explant with a further genetic trait.

Example 1: Cloning and Transformation
1.1 Vector cloning
Standard gene cloning techniques of restriction digestion and ligation of fragments from in-house vectors were used to construct the transformation vectors, pNOV1914 and pNOV4641. Vector pNOV1914 included a selectable marker cassette comprising a Ubiquitin (UBQ3) promoter, the UBQ3 intron, a gene sequence which encodes a protein conferring resistance to hygromycin, and a nos polyadenylation sequence. Vector pNOV4641 included the expression cassette of the target gene, which cassette comprised a Actin (ACT2) promoter, the ACT2 intron, a sequence encoding the Cry IAb gene that had been codon optimised for expression in maize, and a nos polyadenylation sequence.
The vectors were transformed into Agrobacterium tumefaciens strain GV3101 using standard Agrobacterium transformation techniques, and transformed cells selected via antibiotic resistance.
1.2 Plant transformation
The CE44-69D event was produced by Agro bacterium-mediated transformation of Gossypium hirsutum L. cv Coker 312. _ _
Coker 312 seeds were sown in the glasshouse. Tender petioles were cut from 3 to 5 weeks old plants, and sterilized by immersion in 70% ethanol. The petioles were then immersed in a 5% Clorox + 2ml/l Tween20 solution for 20 minutes. Petioles were washed 3 times in ddH2O. The ends of petioles were cut off, and petioles transferred to petiole pre-culture medium (4.3g/l MS salts, B5 vitamins (lOOmg/1 myo-Inositol, lmg/1 nicotinic acid, lmg/1 pyridoxine HCl, lOmg/1 thiamine HCl), 30g/l glucose, 2.4g/l phytogel, pH 7.0) and allowed to pre-culture in the light at 3O0C for 3 days.
2 ml cultures of Agrobacterium containing the pNOV1914 and pNOV4641 constructs were grown overnight in appropriate antibiotics and then diluted with liquid MMSl medium (4.3g/l MS salts, B5 vitamins (lOOmg/1 myo-Inositol, lmg/1 nicotinic acid, lmg/1 pyridoxine HCl, lOmg/1 thiamine HCl), 0.05mg/l 2,4-D, O.lmg/1 kinetin, 30g/l glucose, pH 6.5) to an OD660 of between 0.1 and 0.2.
The ends were cut off the petioles and placed in 10 to 20ml of bacterial solution in a sterile petri dish. Once in the solution, the petioles were cut lengthwise and then cut into 2cm sections. After the petiole explants had soaked in bacterial solution for 5 to 10 minutes, they were transferred to co-culture plates (same recipe as MMSl liquid with the addition of 2.4g/l Phytagel) overlaid with sterile filter papers, and allowed to co-culture at 24°C for 48 to 72 hours under low light intensity. Co-cultured explants were transferred to MMS 1 medium (recipe as for MMSl liquid medium, additionally with 2.4g/l phytogel) containing 500mg/l cefotaxime and lOmg/1 hygromycin, and incubated at 300C under a light cycle of 16 hours light and 8 hours dark. Explants were transferred to fresh medium after 2 weeks, and every 4 to 6 weeks thereafter until callus was formed.
Once calli were the size of a garden pea, they were removed from the explants and transferred to fresh MMSl medium containing 500mg/l cefotaxime and lOmg/1 hygromycin, and maintained in tissue culture by subculturing every 4 weeks as appropriate.
1.5g callus tissue was broken up thoroughly and placed in a 50 ml Erlenmeyer flask containing 10 ml of liquid MMS2 medium (4.3g/l MS salts, B5 vitamins (lOOmg/1 myoinositol, lmg/1 nicotinic acid, lmg/1 pyridoxine HCl, lOmg/1 thiamine HCl), 1.9g/l KNO3, 30 g/1 glucose, pH 6.5). The suspended callus was shaken at 100 rpm in the light at 3O0C for two weeks. The suspension culture cells were rinsed 3 times in MMS2 liquid medium, resuspended and plated onto solid MMS2 medium (recipe as per liquid MMS2 medium, additionally with 2.4g/L phytogel). Once plated, excess liquid MMS2 medium was removed, and the plates incubated at 300C in the light. Plates were checked for somatic embryo development each week. Somatic embryos formed within 1 to 2 months. This step of liquid suspension could be repeated multiple times until embryogenic callus or somatic embryos were formed.
Somatic embryos were transferred to EG (embryoid germimation) medium (2.65g/l MS salts modification No. 4 (Duchefa), 1.9g/l KNO3, B5 vitamins (as before), 30g/l glucose, lg/1 glutamine and 0.5g/l asparagine, pH 6.5), and sub-cultured to fresh EG medium every 3 to 4 weeks.
Once somatic embryos turned green and were larger than 2cm, they were plated root down in EG medium. At all stages of regeneration, growing plantlets were prevented from reaching the lids or sides of their containers to prevent leaf drop. Germinated embryos with 1 to 2 true leaves were transferred to EG medium in 175ml Greiner containers. Strong plantlets with true leaves were transferred to sterile peat plugs expanded with dH2O in 175ml Greiners and transferred to peat in 3 inch pots. Plants were acclimatised in a plant propagator at high humidity in a growth cabinet under conditions of 14 hours daylight at 3O0C and 10 hours darkness at 200C. Once roots were seen growing through the drainage holes of the pot they were transferred to larger pots containing 50% John Innes No. 3 and 50% peat supplemented with Osmocote, and placed in the glasshouse.
1.3 Identification and selection of transgenics
Putative transgenic plants were screened by PCR for the presence of the Cry IAb gene. Positive events were identified and screened using insect bioassays for insecticidal activity. Molecular characterisation of insecticidal lines was carried out by Southern Blot analysis. Tl seed from several events were observed in a field trial for insect resistance and agronomic quality. The CE44-69D event was chosen based on molecular characterisation, protein expression levels as identified by ELISA, insecticidal activity against Heliothis virescens and Spodoptera littoralis and field performance. The hygromycin selectable - ZO -
marker cassette was segregated away using conventional plant breeding to result in the CE44-69D event.
1.4 Verification of sequence ofCE44-69D Genomic DNA was isolated from the CE44-69D event. This was used in the sequencing of the junctions of the DNA insertion site with the cotton genomic DNA in the CE44-69D event (SEQ ID NOs: 1 and 2), using standard DNA sequencing techniques.

Example 4: CE44-69D Detection via Southern Blot
4.1 DNA extraction for use in Southern Blotting _ _
Approximately 2 to 3g fresh weight of frozen young leaf tissue was ground in a chilled mortar and pestle to a fine powder and added to 15 ml of ice-cold Nuclei extraction buffer (0.35M glucose, 0.1M Tris-HCl pH8, 5OmM Na2EDTA, 2% Polyvinylpyrrolidone- 10, 0.1% ascorbic acid, 0.2% B-mercaptoethanol) in a labelled tube. The sample was incubated on ice for 15-20 minutes. The tube was mixed gently and centrifuged at 270Og for 20 minutes at 4°C. The supernatant was discarded and 8ml of nuclei lysis buffer (0.14M sorbitol, 0.22M Tris-Cl pH8, 0.8M NaCl, 0.22M Na2EDTA, 0.8%w/v CTAB, 1% Sarkosyl, 1% Polyvinyl -pyrrolidone- 10, 0.1% ascorbic acid, 0.2% B-mercaptoethanol, 5μg/ml proteinase K) was added. After mixing, the tubes were incubated at 650C for 30 minutes. 10ml chloroform was added, and the tube mixed gently by inversion until an emulsion formed followed by centrifugation at 4600rpm for 10 minutes at room temperature.

The samples are centrifuged at room temperature at 4600 rpm for 10 minutes. The aqueous phase is transferred to a fresh 15ml tube. _ _
0.6 volumes of cold isopropanol are added and the sample is incubated at room temperature for approximately 30 minutes. After mixing by slowly inverting the tube several times, the DNA is spooled out and dissolved in 500ul TE. lOul of lOmg/ml RNAse are added and incubated for 15 minutes at room temperature. Following extraction with 500ul of phenol: chloroform: isoamyl alcohol (25:24:1), the sample is mixed gently and centrifuged at 13000rpm for 5 min.
The supernatant is transferred to a fresh tube using a fine Pasteur pipette and re-extracted with chloroform: isoamyl alcohol (24:1) as above. The supernatant is transferred to fresh tubes, 1/10 volume 3M NaOAc (pH4.8) added and mixed, and then one volume cold isopropanol is added. The sample may be incubated at room temperature for up to 30 minutes to precipitate the DNA. The DNA is spooled out and resuspended in 70% ethanol. The DNA is air-dried to remove the ethanol and resuspended in 200ul water.
4.3 Restriction enzyme digests
The DNA was quantified using a spectrophotometer and running out on a gel. Suitable enzyme digests were prepared using 5ug DNA per digest in a total volume of 40ul. Digests including Ncol, Mscl, Hindlll/Kpnl and Nhel/Ascl were used to detect copy number and insert integrity. Digests were incubated for 6 hours at the appropriate temperature for each enzyme.
4.4 Gel electrophoresis
Bromophenol blue loading dye was added to each sample from 4.3 above, and each sample loaded on a 0.8% TBE agarose gel. The gel was run at 50 volts overnight.
After running, the gel was washed in 0.25M HCl for 10 minutes to depurinate the DNA, incubated in denaturing solution (0.5M NaOH, 1.5M NaCl) with gentle agitation for 30 minutes, rinsed with distilled water and then incubated in neutralising solution (0.5M Tris, 1.5M NaCl) for 30 minutes.
A Southern Blot was prepared as follows: A glass plate was placed over a tray containing 2OX SSC and a strip of 3M paper was placed onto the glass plate such that both ends dipped into the 2OX SSC solution (to act as a wick). A piece of 3M paper the same size as _ _
the gel was placed on the wick, and the gel placed on this. Strips of nescofilm were laid around the edges of the gel to form a seal. A Hybond membrane was placed on top of the gel, followed by two further pieces of 3M paper. Throughout the assembly of the blot, care was taken to ensure that no air bubbles were trapped between the membrane, gel and 3M paper. A 5cm- 1 Ocm stack of absorbent paper towels was placed on top of the 3M paper and held in place with a weight.
The DNA was allowed to transfer to the Hybond membrane overnight. After transfer the Southern Blot stack was disassembled and the DNA was bound to the membrane via UV cross-linking.
4.5 Hybridisation
A suitable DNA probe was prepared by HindIIIIKpnI restriction digestion of binary plasmid pNOV4641 and purification of the resulting fragment. 25ng probe DNA in 45ul TE was boiled for 5 minutes, placed on ice for 5 minutes then transferred to a Rediprime II (Amersham Pharmacia Biotech, #RPN1633) tube. After addition of 5ul 32P-labelled dCTP to the Rediprime tube, the probe was incubated at 37°C for 1 hour . The probe was purified by centrifugation through a microspin G-50 column (Amersham Pharmacia Biotech, #27-5330-01) according to the manufacturers instructions to remove unincorporated dNTPs. The activity of the probe was measured roughly by comparing the amount of radioactive component remaining in the column to the amount in the sample tube, with a ratio of at least 50:50 being acceptable. The Hybond membrane was pre- hybridised by wetting with 40 ml pre-warmed Rapid-Hyb buffer (Amersham-Pharmacia), at 65°C for 30 minutes. The labelled probe was boiled for 5 minutes, and placed on ice for 5 minutes. An appropriate amount of probe (1 million counts per ImI pre-hybridisation buffer) was added to the pre-hybridisation buffer and hybridisation occurred at 65°C overnight. The following day, the hybridisation buffer was discarded, and following a rinse with 50ml 2xSSC/l%SDS solution the membrane washed in 150ml 2xSSC/l%SDS solution at 650C for 30-45 minutes. This process was repeated twice with 0.1 xSSC/1 %SDS solution .The membrane was exposed to a phosphor screen or X-ray film to detect where the probe had bound. -
Example 5: CE44-69D Detection via ELISA
5.1 Protein extraction
Cotton tissue for analysis was harvested and frozen at -70°C. Frozen tissue was ground to a fine powder and weighed into a labelled polypropylene tube. Extraction buffer (10OmM Tris, 10OmM Sodium Borate, 5mM MgCl, 0.05% Tween 20, 0.2% Sodium Ascorbate, Water, pH 7.8, ImM AEBSF, O.OOlmM Leupeptin) was added to the sample in a ratio of 2:1 (volume extraction buffer : sample fresh weight) for frozen tissue or 30:1 (volume extraction buffer : sample dry weight) for lyophilised tissue. The sample was vortexed and homogenised using a Brinkman PT 10/35 Polytron equipped with a PTA IOTS foam- reducing generator, until the mixture became liquefied. Extracts were centrifuged at 10,000 x g for 15 minutes. The protein extract supernatant was stored at 2-8°C.
5.2 ELISA protocol The ELISA procedure used standard techniques as follows. A 96- well plate was soaked in ethanol for 2 hours, and air-dried. The plate was coated with 50ul goat anti-Cry IAb antibody per well and incubated overnight at 2-8°C. After washing three times with IX ELISA wash solution (10OmM Tris, 0.5% Tween-20, 75mM NaCl, pH8.5), the plate was dried briefly by tapping upside down on a paper towel. 150ul blocking solution (1OmM NaPO4, 14OmM NaCl, 1% BSA, 0.02% Sodium Azide, titrated to pH7.4 with NaH2PO4 and Na2HPO4) was added to each well followed by incubation at room temperature for 45 minutes. The plate was washed 3 times as described above.
Cry IAb standards and protein extract samples were applied to appropriate wells of the plate in triplicate, 50ul total volume per well. The plate was incubated at 2-8°C for 1 hour 30 minutes, followed by room temperature for a further 30 minutes. The plate was washed three times with ELISA wash solution, and then incubated at 35-39°C for 1 hour with 50ul rabbit anti-Cryl Ab antibody per well. The plate was washed three times with ELISA wash solution, and incubated at room temperature for 30 minutes with 50ul donkey anti-rabbit antibody conjugated with alkaline phosphatase per well. Following a further three washes with ELISA wash solution, 50ul phosphatase substrate solution was added per well and the plate incubated for 30 minutes at room temperature. The reaction was stopped by addition, of 50ul 3M NaOH per well. The absorbance of the solution in each well was measured at ^ _
405nm using a Ceres 900C multiwell plate reader and the results analysed using KC3 Curve fitting software (Bio-Tek Instruments Inc.)- The concentration of Cry IAb in the samples was calculated by reference to the Cry IAb protein standards.
Example 6: CE44-69D detection via DipStick
6.1 Protein extraction
A piece of leaf tissue approximately 0.2 cm2 was placed in a tube containing extraction buffer. A plastic stirrer was used to extract protein from the tissue, by cutting into and macerating the tissue.
6.2 Dipstick test
A test strip was placed into the tube and incubated for 5 to 10 minutes for the result to develop. The test strip comprised a first band at which anti-Cry IAb antibody was bound, and a second band at which a control antibody was bound. After incubation, a double red line in the result window of the test strip indicated that Cry IAb was present. The lower line indicated the presence of Cry IAb protein while the upper line was a control indicating that the assay was working correctly.
Example 7: Insecticidal efficacy of CE44-69D 7.1 Field trial I - design
Field trials were set up at 6 locations in the US to test the insect resistance of CE44-69D. At each location, duplicate trials were planted in a randomized complete block design, each comprising 4 replicates. Each trial consisted of a plot comprising 4 x 40 ft rows, planted at 3 plants per foot.
At each location, one trial was artificially infested with Heliothis virescens (tobacco budworm) larvae, and the other with Helicoverpa zea (cotton bollworm) larvae when the plants were actively squaring. The trials were subsequently assessed for percentage damage to bolls and squares. The artificial infestations were carried out by spraying eggs in a solution of xanthan gum onto the plants so that the neonate larvae hatched directly onto the plants. Infestations were designed to give approximately 3 eggs per plant.
7.2 Field trial I- results . _
The data presented in the table below are the mean of all assessments taken during the trials: multiple square damage and boll damage ratings have been averaged together to give a mean fruiting body damage rating, and data from all 6 locations has been averaged together.
% damaged fruiting bodies (average of squares and bolls, over 6 trial locations)
Heliothis virescens Helicoverpa zea
Coker312 28.31 39.35
CE44-69D 0.82 2.62
The data clearly show that CE44-69D has excellent resistance to both Heliothis virescens and Helicoverpa zea when compared to the non- transgenic control designated Coker312.
7.3 Field trial II - design
CE44-69D plants were artificially infested with tobacco budworm (Heliothis virescens) eggs, which were obtained from the Southern Insect Management Laboratory in Stoneville, MS 24 to 36 hours prior to artificial infestation. Eggs were mixed into a xanthan gum solution and sprayed onto the terminal area of the cotton plants utilizing a conventional CO2 backpack sprayer. Eggs were sprayed through a flat fan 8006 nozzle at approximately 10 psi. The trial was carried out at 2 locations, Syngenta's Southern Regional Technical Centre at Leland, MS and Vero Beach Research Centre at Vero Beach, FL. At both locations, unreplicated, solid blocks of approximately 2240 plants of CE44-69D, as well as smaller blocks of approximately 224 plants of non-transgenic Coker 312 were utilized for the infestation. If populations of natural enemies were deemed to be sufficiently high to interfere with infestation, the study area was over sprayed with acephate (Orthene®) at 0.5 Ib ai/A 24 to 48 hours before scheduled infestation. The non-transgenic Coker 312 cotton block was used to estimate the infestation technique effectiveness and to determine field fitness of the tobacco budworm strain utilized in these studies. At each location, four artificial infestations were made to CE44-69D and Coker 312 cotton with one quarter of the available plants being infested each time. The infestations were carried out between mid-squaring and early bloom. Egg hatch rate was estimated by collecting several leaves containing eggs from Coker 312 plants and placing them into Petri dishes. Eggs on the - -
collected leaves were counted and two to three days later, successful larval eclosion was assessed. Assessments were carried out 7 days after infestation. One half of all infested plants were assessed at the Leland, MS location, whereas three quarters of all infested plants were assessed at the Vero Beach, FL location. In each case, the assessment involved a thorough whole plant search for surviving larvae. Square damage ratings were also taken from the Leland trial. Where surviving larvae were found on CE44-69D plants, the fruiting structures containing the larva were tagged. Four to 7 days later, these fruiting structures, plus all adjacent structures were thoroughly assessed again to evaluate whether the larvae were still surviving. Similar later assessments were not carried out on the Coker 312 plots because by this stage many of the larvae that had been on these plants had begun to search for pupation sites in the soil.
7.4 Field trial II - results
The table below is a summary of the data collected.
Figure imgf000036_0001
* Estimated based on the number of eggs applied and the observed hatch rate ND = not determined
The larvae surviving on CE44-69D plants 7 days after infestation at both locations were very small, ranging from the first to third instar. The fruiting structures that contained live larvae 7 days after infestation were tagged and assessed again 4 to 7 days later. At the second assessment, no live larvae could be recovered in the tagged, or surrounding fruiting structures. Furthermore, all the tagged fruiting structures remained on the plants and were - —
developing normally. This strongly suggests that the few small larvae that were still alive on CE44-69D plants 7 post after infestation did not survive to the second assessment.
The levels of square damage observed on CE44-69D plants were extremely low in comparison to the non-transgenic Coker 312 control, confirming that the tobacco budworm larvae were vigorous and capable of establishing a robust infestation.
The data from this artificial infestation trial show that CE44-69D has excellent resistance to tobacco budworm when compared to the non-transgenic control designated Coker 312.
