Description

NEMATODE RESISTANT PLANTS AND SEEDS

This application is related to international publication number WO 99/60141, and is a divisional of Canadian patent application SN 2,323,312.
FIELD OF THE INVENTION
The present invention relates to isolated DNA sequences involved in nematode resistance inplants.The invention also relates to~methods for improving the genetic traits for nematode resistance in plants b~~ utilizing such isolated DNA
sequences.
BACKGROUND
Plants are continually attacked by a diverse range of phytopathogenic organisms. These organisms cause substantial losses to crops each year.
Traditional approaches for control of plant diseases have been the use of chemical treatment arid the construction of interspecific hybrids between resistant crops and their wild-type relatives as sources of resistant germplasm. However, environmental and economic concerns make chemical pesticides undesirable, while the traditional interspecific breeding is inefEcient and often cannot eliminate the undesired traits of the wild species. Thus, the discovery of pest and pathogen-resistant genes provides a new approach to control plant disease.
Several genes responsible for disease resistance have been identified and ' isolated from plants. See Staskawicz et al. (1995) Science 268:661-667.
Recently, 2 o the sugar beet Hsl°'°'~ gene that confers resistance to the beet cyst nematode was cloned. See Cai et al: (1997) Science 275:832-834; and Moffat (1997) Science 275:77: Transformation of plants or plant tissues with the resistance genes can confer disease resistance to susceptible strains. See, for example, PCT
Publication W093/19181; and Cai et al. (1997) Science 275:832-834.
2 5 Nematode infection is prevalent in many crops. For example, soybean cyst nematode (Heterodera glycines) is a widespread pest that causes substantial damage 62451-860 (D) to soybeans every year. Such damage is the result of the stunting of the soybean plant caused by the cyst nematode.
The stunted plants have smaller root systems, show symptoms of mineral deficiencies in their leaves, and wilt easily.
The soybean cyst nematode is believed to be responsible for yield losses in soybeans that are estimated to be in excess of $500 million per year.
Nematicides such as Aldicarb and its breakdown products are known to be highly toxic to mammals. As a result, government restrictions have been imposed on the use of these chemicals. Thus, there is a great need for the isolation of genes that can provide an effective method of controlling nematodes without causing health and environmental problems.
SUMMARY OF THE INVENTION
This invention relates to DNA sequences isolated from soybean and maize. The sequences alone, or in combination with other sequences, confer nematode resistance in a plant. The sequences are useful in methods for the protection of plants from nematodes. Additionally, allelic variants of the resistance gene from a susceptible plant are included. In another aspect of the present invention, expression cassettes and transformation vectors comprising the isolated nucleotide sequences are disclosed. The transformation vectors can be used to transform plants and express the nematode resistance genes in the transformed cells. Plants susceptible to nematode infection can be targeted to confer nematode resistance. The transformed cells as well as the regenerated transgenic plants containing and expressing the isolated DNA and protein sequences are also disclosed.

DETAILED DESCRIPTION OF THE INVENTION
Compositions and methods for the control of nematodes in susceptible plants are provided. The compositions comprise isolated proteins and DNA sequences encoding such proteins involved in nematode resistance. Such isolated 'DNA
sequences can be transferred into plants to confer or improve nematode resistance in the transformed plants. Sequences of the invention have been isolated from maize and soybean. By "involved in nematode resistance" is intended that the proteins or sequences, either alone or in combination with other proteins or sequences, confer nematode resistance in a plant. In this manner, resistance to nematodes can be enhanced or improved in the transformed plant as at least one of the sequences required for nematode resistance is provided.
DNA sequences isolated from the genomes of maize and soybean are disclosed. The nucleotide sequences and amino acid sequences from two maize isolates are set forth in SEQ ID NOs: 1-2 and 3-4, and the corresponding sequences from two soybean isolates are set forth in SEQ ID NOs: 5-6 and 7-8. The nucleotide sequences in accordance with this invention are involved in nematode resistance in 1 S plants and may confer, alone or in combination with other sequences, nematode resistance in plants. Also discussed are DNA sequences isolated from a susceptible genotype of soybean. The nucleotide and amino acid sequences for this isolate are set forth in SEQ ID NOs: 9-10. Nucleotide sequences of the invention also include the maize and soybean nematode resistance gene sequences as contained in plasmids deposited with American Type Culture Collection (ATCC) and assigned Accession Numbers 209366, 209365, 209614, 209363, and 209364.
Using the sequence information set forth in the SEQ ID NOs or the sequences as contained in ATTC deposits assigned Accession Numbers 209366, 209365, 209614, 209363, and 209364, other plant DNA sequences comprising the nucleotide sequences disclosed above can be isolated based on sequence homology at either the amino acid or nucleotide sequence level. Any suitable molecular cloning method can be used including, but not limited to, PCR'amplification and DNA
hybridization. In the same manner, synthetic nucleotide sequences can be designed based on the amino acid sequences of the invention. Methods to design and make such synthetic sequences are available in the art.
In a hybridization method, the hybridization probes may be genomic DNA
fragments, cDNA fragments, RNA fragments, or other oligonucleotides, and may be labeled with a detectable group such as 3ZP, or any other detectable marker.
Probes for hybridization can be made by labeling synthetic oligonucleotides based on the sequence of the soybean and/or maize sequence. Degenerate primers designed on the basis of conserved nucleotide or amino acid sequences in the maize and soybean sequences can additionally be used. Preparation of probes for hybridization is generally know in the art and is disclosed in Sambrook et al. ( 1989) Molecular Cloning: A Laboratory Manual (2d ed.. Cold Spring Harbor Laboratory Press.
Plainview, New Yorkj.~ The labeled probes can be used to screen cDNA or genomic libraries made from nematode resistant plants.
Methods for construction of such cDNA and genomic libraries are generally known in the art and are disclosed in Sambrook et al. (1989).Molecular Cloninh: A
Laboratort:
Manual (2d ed.. Cold Spring Harbor Laboratory Press. Plainviev-. New York).
In a PCR method. the DNA or amino acid sequence encoded by the soybean or maize sequences of the invention can be aligned with each other. Nucleotide 1 S primers can be designed based on any conserved short stretches of amino acid sequences or nucleotide sequences. Pairs of primers can be used in PCR
reactions for amplification of DNA sequences from cDNA or genomic DNA extracted from plants of interest. In addition. a single specific primer with a sequence corresponding to one of the nucleotide sequences disclosed herein can be paired with a primer having a sequence of the DNA vector in the cDNA or genomic libraries for PCR
amplification of the sequences ~' or 3' to the nucleotide sequences disclosed herein.
Similarly.
nested primers may be used instead of a single specific primer for the purposes of the invention. Methods for designing PCR primers and PCR cloning are generally known in the art and are disclosed in Sambrook et al. (1989) Molecular Cloning: A
Laboratory Manual (2d ed.. Cold Spring Harbor Laboratory Press, Plainview, New York).
The sequences of the invention comprise coding sequences from other plants that may be isolated according to well-known techniques based on their sequence homology to the maize or soybean coding sequences set forth herein. In these techniques, all or part of the known coding sequence is used as a probe that selectively hybridizes to other possible nematode resistance coding sequences present in a population of cloned genomic DNA fragments or cDNA fragments (i. e., genomic or cDNA libraries) from a chosen organism. To achieve specific hybridization under a variety of conditions, such probes include sequences that are unique and are preferably at least about 10 nucleotides in length. and most preferably at least about 20 nucleotides in length. Such probes may be used to amplify corresponding coding S sequences from a chosen organism by PCR. This technique may be used to isolate other possible nematode resistance coding sequences from a desired organism or as a diagnostic assay to determine the presence of the nematode resistance coding sequence m an organism.
Such techniques include hybridization screening of plated DNA libraries (either plaques or colonies; see, e.g., Innis et al.. eds. (1990) PCR
Protocols: A Guide to Methods and Applications (Academic Press. New York)).
The isolated DNA sequences further comprise DNA sequences isolated from other plants by hybridization with partial sequences obtained from maize and soybean. Conditions that will permit other DNA sequences to hybridize to the DNA
1 S sequences disclosed herein can be determined in accordance with techniques generally known in the art. For example, hybridization of such sequences may be carried out under conditions of reduced stringency. medium stringency. or high stringency conditions (e.g., conditions represented by a wash stringency of 3~-40°ro Formamide with Sx Denhardt's solution. 0.~% SDS. and lx SSPE at 37°C;
conditions represented by a wash stringency of 40-45% Forniamide with Sx Denhardt's solution.
0.5% SDS. and lx SSPE at 42°C; and conditions represented by a wash stringenc~~ of ~0% Formamide with Sx Denhardt's solution, 0.~% SDS, and lx SSPE at 42°C.
respectively. See Sambrook et al. (1989) Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Plainview, New York). In general.
sequences that confer nematode resistance and hybridize to the DNA sequences disclosed herein will be at least 70-75% homologous, 80-85% homologous. and even 90-95% homologous or more.
The following terms are used to describe the sequence relationships bet«~een two or more nucleic acids or polynucleotides: (a) "reference sequence", (b) "comparison window", (c) "sequence identity". (d) "percentage of sequence identiy", and (e) "substantial identity".
(a) As used herein, "reference sequence" is a defined sequence used as a basis for sequence comparison. A reference sequence may be a subset of or the entire specified sequence; for example, as a segment of a full-length cDNA
or gene sequence, or the complete cDNA or gene sequence.
(b) As used herein, "comparison window" makes reference to a contiguous and specified segment of a polynucleotide sequence, wherein the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. Generally, the comparison window is at least 20 contiguous nucleotides in length, and optionally can be 30, 40, 50, 100, or more contiguous nucleotides in length. Those of skill in the art understand that to avoid a high similarity to a reference sequence due to inclusion of gaps in the polynucleotide sequence a gap penalty is typically introduced and is subtracted from the number of matches.
Methods of alignment of sequences for comparison are well-known in the art.
I S Optimal alignment of sequences for comparison may be conducted by the local homology algorithm of Smith and Waterman ( 1981 ) Adv. Appl. Math. 2:482; b~~
the homology alignment algorithm of Needleman and Wunsch ( 1970) J. Mol. Biol.
48:443; by the search for similarity method of Pearson and Lipman ( 1988) Proc. Natl.
Acad Sci. 85:2444; by computerized implementations of these algorithms.
including, but not limited to: CLUSTAL in the PC/Gene program by Intelligenetics (Mountain View, California). GAP. BESTFIT. BLAST, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group (GCG) (57~ Science Drive, Madison, Wisconsin); the CLUSTAL program is well described by Higgins and Sharp (1988) Gene 73:237-244; Higgins and Sharp (1989); CABIOS S:l~l-153:' Corpet et al. ( I 988) Nucleic Acids Res. 16:10881-90; Huang et al. ( 1992) Computer Applications in the Biosciences 8:155-65; and Person et al. ( 1994) Meth. of Mol. Biol.
24:307-331; preferred computer alignment methods also include the BLASTP.
BLASTN, and BLASTX algorithms. See Altschul et al. (1990) J. Mol. Biol. 21 ~:403-410. Alignment is also often performed by visual inspection and manual alignment.
(c) As used herein. "sequence identity" or "identity" in the context of two nucleic acid or polypeptide sequences includes reference to the residues in the two sequences that are the same when aligned for maximum correspondence over a v~0 99/60141 PCT/US98/27450 specified comparison window. When percentage of sequence identity is used in reference to proteins, it is recognized that residue positions that are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (e.g., charge or hydrophobicity) and therefore do not substantially change the functional properties of the molecule. Where sequences differ in conservative substitutions, the percentage of sequence identity may be adjusted upward to correct for the conservative nature of the substitution. Sequences that differ by such conservative substitutions are said to have "sequence similarity" or "similarity." Means for making this adjustment are well-known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch. thereby increasing the percentage of sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and I . The scoring of conservative 1 S substitutions is calculated, e.g., as implemented in the program PC/GENE
(Intelligenetics, Mountain View, California).
(d) As used herein, "percentage of sequence identity" means the value determined by comparing two optimally aligned sequences over a comparison windov~~, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions or deletions (i. e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison and multiplying the result by 100 to yield the percentage of sequence identity.
(e)(i) The term "substantial identity" of polynucleotide sequences means that a polynucleotide comprises a sequence that has at least 70%
sequence identity, preferably at least 80%, more preferably at least 90% and most preferably at least 95%, compared to a reference sequence using one of the alignment programs described using standard parameters. One of skill in the art will recognize that these values can be appropriately adjusted to determine corresponding identity of proteins _g_ encoded by two nucleotide sequences by taking into account codon degeneracy amino acid similarity, reading frame positioning, and the like. Substantial identity of amino acid sequences for these purposes normally means sequence identity of at least 60%, more preferably at least 70%, 80%, 90%, and most preferably at least 95%.
Another indication that nucleotide sequences are substantially identical is if two molecules hybridize to each other under stringent conditions. Generally, stringent temperature conditions are selected to be about 5°C to about 2°C lower than the melting point (Tm) for the specific sequence at a defined ionic strength and pH.
The denaturation or melting of DNA occurs over a narrow temperature range and represents the disruption of the double helix into its complementary single strands.
The process usually is characterized by the temperature of the midpoint of transition, T~,. which is sometimes described as the melting temperature. Formulas are available in the art for the determination of melting temperatures. Typically. stringent wash conditions are those in which the salt concentration is about 0.02 molar at pH
7 and I S the temperature is at 50, 55, or 60°C. However, nucleic acids that do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides that they encode are substantially identical. This may occur, for example, when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. One indication that two nucleic acid sequences are substantially identical is that the poIypeptide that the first nucleic acid encodes is immunologically cross reactive with the polypeptide encoded by the second nucleic acid.
(e)(ii) The terms "substantial identity" in the context of a peptide indicates that a peptide comprises a sequence with at least 70% sequence identity to a reference sequence, preferably 80%, more preferably 85%, most preferably at least 90°io or 95% sequence identity to the reference sequence over a specified comparison windov<-. Preferably, optimal alignment is conducted using the homology alignment algorithm of Needleman and Wunsch ( 1970) J. Mol. Biol. 48:443. An indication that two peptide sequences are substantially identical is that one peptide is immunologically reactive with antibodies raised against the second peptide.
Thus, a peptide is substantially identical to a second peptide, for example, where the two peptides differ only by a conservative substitution. Polypeptides that are . ,'s "substantially similar" share sequences as noted above except that residue positions that are not identical may differ by conservative amino acid changes.
The present invention also encompasses the proteins and peptides encoded by the nucleotide sequences of this invention. It is recognized that the proteins of the invention may be oligomeric and will vary in molecular weight. component peptides, activity, and in other characteristics. The proteins of the invention can be used to protect plants against nematodes. Such methods are described in more detail below.
Fragments and variants of the disclosed nucleotide sequences and proteins encoded thereby are also encompassed by the present invention. By "fragment"
is intended a portion of the nucleotide sequence or a portion of the amino acid sequence and hence protein encoded thereby. Fragments of a nucleotide sequence may encode protein fragments that retain the biological activity of the native protein and hence confer resistance to nematodes. Alternatively. fragments of a nucleotide sequence that are useful as hybridization probes generally do not encode fragment proteins retaining biological activity. Thus, fragments of a nucleotide sequence may range from at least about 20 nucleotides, about 50 nucleotides, about 100 nucleotides. and up to the entire nucleotide sequence encoding the proteins of the invention.
By "variants" is intended substantially similar sequences. For nucleotide sequences, conservative variants include those sequences that, because of the degeneracy of the genetic code, encode the amino acid sequence of one of the proteins conferring resistance to nematodes. Generally. nucleotide sequence variants of the invention will have at least 70%, generally, 80%, preferably up to 90%
sequence identity to its respective native nucleotide sequence.
By "variant" protein is intended a protein derived from the native protein by deletion (so-called truncation) or addition of one or more amino acids to the N-terminal and/or C-terminal end of the native protein; deletion or addition of one or more amino acids at one or more sites~in the native protein; or substitution of one or more amino acids at one or more sites in the native protein. Such variants may result from. for example, genetic polymorphism or from human manipulation. Methods for such manipulations are generally known in the art.
Thus, the proteins of the invention may be altered in various ways including amino acid substitutions, deletions, truncations, and insertions. Methods for such 62451-860(S) manipulations are generally known in the art. For example, amino acid sequence variants of the proteins can be prepared by mutations in the DNA. Methods for mutagenesis and nucleotide sequence alterations are well known in the art.
See_ for example, Kunkel (1985) Proc. Natl. Acad. Sci. USA 82:488-49?; Kunkel et al.
(1987) Methods in Enrymol. 154:367-382; U.S. Patent No. 4.873,192; Walker and Gaastra, eds. (1983) Techniques in Molecular Biology (MacMillan Publishing Company. New York) and the references cited therein. Thus, the genes and nucleotide sequences of the invention include both the naturally occurring sequences as well as mutant forms.
Likewise, the proteins of the invention encompass both naturally occurring proteins as _ w~el1 as variations, fragments, and modified forms thereof. Such variants will;
continue to possess the desired activity of conferring resistance to nematodes.
Obviously. the mutations.that will be made in the DNA encoding the variant must not place the sequence out of reading frame and preferably will not create sequences deleterious to expression of the gene.product. See, EP Patent Application Publication No.75,444.
The nematode resistance genes of the invention can be optimized for enhanced expression in plants of interest. See, for example, EPA0359472; EPA0385962:
W091/16432; Perlak et al. (1991) Prnc. Natl. Acad. Sci. USA 88:3324-3328: and Murray et al. (1989) Nucleic Acids Res. 17:477-498. In this manner, the genes can be synthesized utilizing.plant-preferred colons. See, for example, Murray et al.
(1989) . Nucleic Acids Res. 17:477-498. In this manner, synthetic genes can also be made based on the distribution of colons a particular host uses for a particular amino acid. Thus, the nucleotide sequences can be optimized for expression in any plant. It is recognized that ali or any part of the gene sequence may be optimized or synthetic. That is, synthetic or partially optimized sequences may also be used.
The present invention also relates to a recombinant DNA transformation construct comprising the isolated DNA sequences involved in nematode resistance in plants. The recombinant DNA transformation construct can be introduced into plant cells, prbtoplasts, calli, tissues, or whole plants to confer nematode-resistance properties in plants.
The sequences of the invention can be constructed in expression cassettes for 62451-860 (S) expression in a plant. Such expression cassettes will comprise a transcriptional initiation region linked to the gene encoding the gene of interest. Such an expression cassette is provided with a plurality of restriction sites for insertion of the gene of interest behind the regulatory control of a designated promoter. The expression cassette may additionally contain selectable marker genes suitable for the particular host organism.
The transcriptional initiation region, the promoter, may be native or analogous or foreign or heterologous to the host. Additionally, the promoter may be the natural sequence or alternatively a synthetic sequence. By foreign is intended that the transcriptional initiation region is not found in the wild-type host into which the transcriptional initiation region is introduced. As used herein a chimeric gene comprises a coding sequence operably linked to a transcription initiation region which is heterologous to the coding sequence. While any promoter or promoter element capable of driving expression of a coding sequence can be utilized. of particular interest for expression in plants are root promoters (Bevan et al. (1993) in Gene Conservation and Exploitation: Proceedings of the 20th Stadler Genetics Symposium, ed. Gustafson et al. (Plenum Press, New York) pp. 109-129; Brears et al.

The ttanscriptional cassette will include in the 5'-to-3' direction of transcription, transcriptional and translational initiation regions, a DNA
sequence of interest, and transcriptional and translational termination regions functional in plants.
The termination region may be native with the transcriptional initiation region, may be native with the DNA sequence of interest, or may be derived from another source.

For the expression of the proteins encoded by the isolated DNA sequences of the present invention. a promoter capable of facilitating gene transcription in plant cells must be operable linked to the nematode resistance gene sequence. A
variety of suitable promoters are generally known in the art. Both constitutive promoter and tissue-specific promoters can be used. A constitutive promoter is a promoter that can initiate RNA transcription in any tissue or cell in a plant, while tissue-specific promoters can do so only in specific tissues. Suitable promoters are known in the art WO 99/60141 PCT/US98t2745~b and include 35S and I 9S promoter of CaMV. Agrobacterium NOS (nopaline symthase) gene promoter, and the Agrobacterium mannopine synthase gene promoter.
For tissue specific expression, the isolated DNA sequences of the invention conferring nematode resistance can be operably linked to tissue specific promoters.
In addition, a marker gene for identifying and selecting transformed cells.
tissues, or plants may be included in the transformation construct. By marker gene is intended to be either reporter genes or selectable marker genes.
Reporter genes are generally known in the an. The reporter gene used should be exogenous and not expressed endogenously. Ideally the reporter gene will exhibit low- background activity and should not interfere with plant biochemical and physiological activities. The products expressed by the.reporter gene should be stable and readily detectable. It is important that the reporter gene expression should be able to be assayed by a non-destructive., quantitative, sensitive, easy to perform and inexpensive method.
Examples of suitable reporter genes known in the art can be found in, for example, Jefferson et al. (1991 ) in Plant Molecular- Biology Manual, ed.

It is further recognized that the components of the transformation construct may be modified to increase expression. For example, truncated sequences, nucleotide substitutions or other modifications may be employed. See, for example, Perlak et al. (1991 ) Proc. Natl. Acad Sci. USA 88:3324-3328; Murray et al. ( 1989) Arcleic Acids Res. 17:477-498; and W091/16432.
In preparing the transformation construct, the various DNA fragments may be manipulated, so as to provide for the DNA sequences in the proper orientation and, as appropriate in the proper reading frame. Toward this end, adapters or linkers may be employed to join the DNA fragments or other manipulations may be involved to provide for convenient restriction sites, removal of superfluous DNA, removal of restriction sites. or the like. For this purpose, in vitro mutagenesis, primer repair.
restriction. annealing, resection, ligation. PCR, or the like may be employed.
where insertions, deletions. or substitutions, e.g., transitions and transversions, may be involved.
The present invention also relates to the introduction of the transformation constructs into plant protoplasts, calli, tissues, or organ explants and the regeneration of transformed plants expressing the nematode resistance gene. The compositions of the present invention can be used to transform any plant. In this manner, genetically modified plants, plant cells, plant tissue, seed, and the like can be obtained.
Transformation protocols may vary depending on the type of plant or plant cell. i. e., monocot or dicot. targeted for transformation. Suitable methods of transforming plant cells include microinjection (Crossway et al. (1986) Biotechniques 7:320-334).

Plant tissues suitable for transformation include but are not limited to leaf tissues, root tissues, shoots, meristems. and protoplasts. For soybean it is often preferred to utilize explants of cotyledons.
For example, the Agrobacterium tumefaciens strain A208 is known to be highly virulent on soybean and to give rise to a higher rate of transformation. See Byme et al. (1987) Plant Cell Tissue and Organ Culture 8:3-I5. The transformation of soybean protoplasts by co-culturing them with Agrobacterium tumefaciens or Agrobacterium rhizogenes has been known.
See Facciotti et al. (1985) Biotechnology (NeH~ y'ork) 3:241. Tissue explants may be inoculated with the bacterium for transformation. For example, U.S. Patent No.
5.569,834 issued to Hinchee et al. discloses a method for soybean transformation and regeneration by inoculating a cotyledon explant that is tom apart at the cotyledonary node.
Alternatively, plants can also be transformed successfully by the biolistic technique. which involves using high velocity microprojectiles carrying microparticles containing the transformation construct to propel the microparticles into a plant cell, protoplast, or tissue. The high velocity microprojectile penetrates the outer cell surface without destroying the cell and injects the microparticles into the cells. The transformation construct in the microparticles is thereafter released and incorporated into the cell genome. This technique is also known as particle bombardment and is disclosed in U.S. Patent Nos. 4,945.050, 5,036,006, and x.100,792, which are hereby incorporated by reference. The key advantage of this technique is that it works on virtually any plant tissue. An example of successful transformation of soybean using this particle bombardment technique is demonstrated in McCabe et al. (1988) Biotechnology 6:923-926.
In yet another method of transformation, protoplasts are transfected directly with expression vector DNA that contains the nematode-resistance gene by electroporation or DNA-protoplast co-precipitation in accordance with procedures generally known in the art. See Christou et al. (1987) Proc. Natl. Acad. Sci.
USA
84:3962-3966; Lin et al. (1987) Plant Physiol. 84:856-861.
Once the transformation construct containing the isolated DNA sequences of this invention has been delivered, protoplasts, cells, or tissues expressing the protein encoded by the isolated nematode resistance gene are selected. Selection can be based on the selectable marker that is incorporated in the transformation construct or by culturing the protoplasts, cells, or tissues in media containing one of the antibiotics or herbicides. Alternatively, nematode-resistance may be directly selected by inoculating nematodes into the transformed protoplasts, cells, or tissues.
Both methods of selection are generally known in the art.
A further aspect of the present invention relates to the regeneration of transgenic plants that express nematode resistance genes of the invention. The cells that have been transformed and selected for expression of the sequence of this invention may be grown into plants in accordance with conventional ways. See.
for example, McCormick et al. (1986) Plant Cell Reports 5:81-84. These plants may then be grown. and either pollinated with the same transformed strain or different strains, the resulting hybrid having the desired genetic traits necessary for nematode-resistance.
For example. in soybean, transgenic soybean regeneration has been successful 62451-860(S) from tissues such as nodal axillary buds transformed with elec~roporation-mediated gene transfer technique (Chowrira et al. (1996) Mol. Biotechnol. 5:85-96);
somatic embryos transformed using microprojectile bombardment (Stewart et al. (1996) Plafzt Physiol. 112:121-129); and cotyledon explants that are tom apart at the cotyledonary node and are uansformed by Agrobacterium inoculation (LJ.S. Patent No.
5,569.834 issued to Hinchee et al.). Other methods for regenerating soybean plants are disclosed in U.S. Patent No. 4,684,612 issued to Hemphill et al., and U.S.
Patent No.
4,992.375 issued to Wright.
The sequences of the invention are generally introduced into plants wherein the plant in its native state does not contain the DNA sequences. However. it is recognized that in some plants the gene may occur but does not confer resistance because of aberrant expression, a mutation in the sequence, a nonfunctional protein.
and the like. It will be beneficial to transform such plants with the sequences of the invention.
Using cells and tissues of the present invention that are resistant to nematodes helps to obviate the problem of nematode infection of the host cells and tissues in the culture. In addition, the cells and tissues according to the present invention can also be valuable in the elucidation of the mechanism underlying the plant resistance to pathogens. Such plants include maize, oats, wheat. rice, barley. sorghum, alfalfa.
tobacco, cotton. sugar beet, sunflower, carrot, canola, tomato, potato, oilseed rape.
cabbage, pepper. lettuce, brassicas. tobacco, and soybean.
It is recognized that resistance to nematodes may be multigenic and quantitative in certain plants. Thus, the sequences disclosed herein may be useful alone or in combination with other sequences. Breeding programs have produced mane genotypes that have varying numbers of the genes responsible for nematode resistance.
Thus, the isolated DNA sequences of the invention are preferably used to transform plants expressing one or more other nematode resistance genes. Such plants may be naturally occurring, produced by breeding programs, or produced b~~
transformation with other nematode resistance genes. The result of the transformation with the isolated nematode resistance gene of this invention improves the plants capacity for nematode resistance.

Cotransformation may be conducted to introduce the DNA sequences of this invention into plants together with one or more other nematode resistance genes. In the transformation construct, the other known nematode resistance genes may be contained on the same plasmid as the DNA sequence of this invention or may be contained on a separate plasmid or DNA molecule. The methods for making transformation constructs having the other known nematode resistance gene with or without a DNA sequence isolated in this invention are similar to the methods described above and should be apparent to a person skilled in the art.
Several methods of cotransformation of plants have been developed.
Cotransformation is easily accomplished by DNA mediated processes, such as the co-precipitation method, biolistic method. and electroporation. Each of these methods is adequately suited for the introduction of the DNA sequences of this invention and other nematode resistance genes, on the same or separate plasmids, into the plant cells. Alternatively, Agrobacterium tumefaciens-mediated cotransformation techniques can be employed. Examples of such techniques can be found in, for example, Depicker et al. (1985) Mol. Gen. Genet. 201:477-484; McKnight et al.
(1987) Plant Mol. Biol. 8:439-445; De Block et al. (1991) Theor. Appl. Genet.
8?:257-263; de Framond et al. (1986) Mol. Gerz Genet. 202:125-131; and Komari et al. ( 1996) The Plant Journal 10: I 65-174. In an alternative method, multiple transgenes may be brought together by breeding of separately transformed parent plants.
The following examples are offered by way of illustration and not by wav of limitation.

EXAMPLES
Example 1: Incorporation of DNA Sequences Conferring Nematode Resistance into Expression Vectors Genomic DNA sequences spanning the full length coding regions of gene fragments conferring nematode-resistance to maize and soybean were isolated and cloned. These sequences are set forth in SEQ ID NOs: 1 and 3 (maize) and 5 and (soybean). Plasmids containing these sequences have been deposited with American Type Culture Collection (ATCC) on October 1 S, 1997, and on February 4, 1998 and are assigned Accession Numbers 209366, 209365, 209614, 209363, and 209364.
Gene fragments are cloned into a plasmid vector, such as that shown in Figure 6, in the sense orientation so that they are under the transcriptional control of a constitutive promoter. The transformation construct is then available for introduction into soybean cells by bombardment methods as described in Example 2.
Example 2: Transformation of Soybean Cells and Regeneration of Transgenic Plants Having Improved Nematode Resistance Initiation and Maicitenance of EmbryoQenic Suspension Cultures Embryogenic suspension cultures of soybean (Glycine max Merrill) are initiated and maintained in a 10A40N medium supplemented with 5 mM asparagine as described previously (Finer and Nagasowa (1988) Plant Cell Tissue Org.
Culi.
15:125-136). For subculture, two clumps of embryogenic tissue, 4 mm in diameter, are transferred to 35 ml of 10A40N medium in a 125-ml delong flask. High quality embryogenic material is selectively subcultured monthly at this low inoculum density.
Preparation of DNA and Tungsten Pellets Plasmid DNA from Example 1 is precipitated onto 1.1 ~tm (average diameter) tungsten pellets using a CaCl2 precipitation procedure (Finer and McMullen (1990) Plant Cell Rep. 8:586-589). The pellet mixture containing the precipitated DNA
is gently resuspended after precipitation, and 2 ~1 is removed for bombardment.
errneTr~rr~ cmr~r~r .v WO 99/60141 PCT/US98l27456 Preparation of Plant Tissue for Bombardment Approximately 1 g of embryogenic suspension culture tissue (taken 3 weeks after subculture) is transferred to a 3.5-cm-diameter petri dish. The tissue is centered in the dish, the excess liquid is removed with a pipette, and a sterile 500 pm pore size nylon screen (Tetko Inc., Elmsford, New York) is placed over the embryonic tissue.
Open petri dishes are placed in a laminar-flow hood for 10 to 15 minutes to evaporate residual liquid medium from the tissue. The 3.5-cm-diameter petri dish is placed in the center of a 9-cm-diameter petri dish immediately before bombardment.
Bombardments are performed using a DuPont Biolistics Particle Delivery System (model BPG). Each sample of embryogenic soybean tissue is bombarded once.
Selection for Transgenic Clones Bombarded tissues are resuspended in the 1 OA40N maintenance medium.
One to two weeks after bombardment the clumps of embryogenic tissue are resuspended in fresh 10A40N medium containing a selection agent, such as kanomycin or hygromycin. The selection agent is filter-sterilized before addition to liquid media. The medium containing a selection agent is replaced with fresh antibiotic-containing medium weekly for 3 additional weeks.
Six to eight weeks after the initial bombardment, brown clumps of tissue that contain yellow-green lobes of embryogenic tissue are removed and separately subcultured in 10A40N medium containing selection agent. After 3 to 4 months of maintenance in this medium, proliferating embryogenic tissues are maintained by standard subculture in 10A40N without added antibiotic. Embryogenic tissues are periodically removed from I OA40N medium containing selection agent and 10A40N
for embryo development and Southern hybridization analyses.
Embrvo Development and Germination For embryo development. clumps of kanamycin-resistant embryogenic tissues are placed at 23°C on the embryo development medium, which contains MS
salts (Murashige and Skoog (1962) Physiol. Plant 15:474-497), B5 vitamins (Gamborg et al. (1968) Exp. Cell. Res. 50:151-158). 6% maltose, and 0.2% gelrite (pH 5.7).
One WO 99/60141 PCT/US98I2745b month after plating, the developing embryos are cultured as individual embryos, 25 per 9-cm-diameter petri dish in fresh embryo development medium. After an additional 4 weeks, the mature embryos are placed in dry petri dishes for 2 to 3 days.
After the desiccation treatment, the embryos are transferred to a medium containing MS salts, BS vitamins, 3% sucrose, and 0.2% Gelrite (pH 5.7). After root and shoot elongation, plantlets are transferred to pots containing a 1:1:1 mixture of vermiculite, topsoil. and peat, and maintained under high humidity. Plantlets are gradually exposed to ambient humidity over a 2-week period and placed in the greenhouse.
where they are grown to maturity and monitored for expression of the nematode resistance gene.
DNA Extraction and~Southern Hybridization Analysis DNA is extracted from embryogenic tissue and leaves using the CTAB
procedure (Saghai-Maroof et al. (1984) Proc. Natl. Acad. Sci. USA 81:8014-8018).
Digested DNAs are electrophoresed on a 0.8% agarose gel. The DNA in the gels is 1 ~ treated with 0.2 N HCI, twice for 1 ~ minutes, followed with 0.5 M
NaOH/0.1 M 1.~
M NaCI, twice for 30 minutes, and finally 1 M NHaCzH302/0.1 M NaOH, for 40 minutes. The DNA is transferred (Vollrath et al. ( 1988) Proc. Natl. Acad.
Sci. USA
8:6027-6031 ) to nylon membranes (Zetaprobe-BioRad, Richmond, California) overnight by capillary transfer using l M NH4C~H30z/0.1 M NaOH. The membranes are baked at 80°C for 2 hours under vacuum and then prehybridized for 4 to 6 hours at 6~°C in SO mM Tris pH 8.0, Sx standard saline citrate (SSC). 2x Denhardt's. 10 mM
Na~EDTA, 0.2% sodium dodecyl sulfate (SDS). and 62.~ ~tg/ml salmon sperm DNA.
