Definitions
- D2j This invention pertains to hybrids of. and cuhivars derived from the rice cultivar designated 'CL151.'
- Rice is an ancient agricultural crop, and remains one of the world's principal food crops. There are two cultivated species of rice: Oryza saliva /,. , the Asian rice, and O. glaberrima St ⁇ iui, the African rice. Oryza sativa L. constitutes virtually all of the world's cultivated rice and is the species grown in the United States. Three major rice producing regions exist in the United States: the Mississippi Delta (Arkansas, Mississippi, northeast Louisiana, southeast Missouri), the Gulf Coast (southwest Louisiana, southeast Texas); and the Central Valley of California. See generally United States Patent No. 6,91 1,589. [0004] Rice is a semiaquatic crop that benefits from flooded soil conditions during part or all of the growing season.
- rice is typically grown on flooded soil to optimize grain yields.
- Heavy clay soils or silt loam soils with hard pan layers about 30 cm below "the surface are typical rice-producing soils, because they reduce water loss from soil percolation.
- Rice production in the United States can be broadly categorized as either dry- seeded or water-seeded. In the dry-seeded system, rice is sown into a well-prepared seed bed with a grain drill or by broadcasting the seed and incorporating it with a disk or harrow. Moisture for seed germination comes from irrigation or rainfall. Another method of dry- seeding is to broadcast the seed by airplane into a flooded field, and then to promptly drain the water from the field.
- One method of water-seeding is to soak rice seed for 12 to 36 hours to initiate germination, and then to broadcast the seed by airplane into a flooded field.
- the seedlings emerge through a shallow flood, or the water may be drained from the field for a short period of time to enhance seedling establishment.
- a shallow flood is then maintained until the rice approaches maturity.
- the fields are drained when the crop is mature, and the rice is harvested. 2 to 3 weeks later with large combines.
- Plant breeding begins with the analysis and definition of problems and weaknesses of the current germplasm, the establishment of program goals, and the definition of specific breeding objectives.
- the next step is selection (or generation) of germplasm that possess the traits to meet the program goals.
- the goal is often to combine in a single variety an improved combination of desirable traits from two or more ancestral germplasm lines.
- These traits may include such things as higher seed yield, resistance to disease or insects, better stems and roots, tolerance to low temperatures, and better agronomic characteristics or grain quality.
- breeding and selection methods depends on the mode of plant reproduction, the heritability of the trait(s) being improved, and the type of seed that is used commercially (e.g., Fj hybrid, versus pure line or inbred cultivars). For highly heritable traits, a choice of superior individual plants evaluated at a single location may sometimes be effective, while for traits with low or more complex heritability, selection is often based on mean values obtained from replicated evaluations of families of related plants. Selection methods include pedigree selection, modified pedigree selection, mass selection, recurrent selection, and combinations of these methods. f ⁇ Ollj The complexity of inheritance influences the choice of breeding method.
- a particularly difficult task is the identification of individual plants that are, indeed, genetically superior.
- a plant's phenotype results from a complex interaction of genetics and environment.
- One method for identifying a genetically superior plant is to observe its performance relative to other experimental plants and to a widely grown standard culfivar raised in an identical environment. Repeated observations from multiple locations can help provide a better estimate of its genetic worth.
- the goal of rice breeding is to develop new, unique, and superior rice c ⁇ ltivars and hybrids.
- the breeder initially selects and crosses two or more parental lines, followed by self pollination and selection, producing many new genetic combinations.
- the breeder can generate billions of different genetic combinations via crossing, selling, and mutation breeding.
- the traditional breeder has no direct control at the molecular level. Therefore, two traditional breeders working independently of one another will never develop the same line, or even very similar lines, with the same traits.
- Hybrid seed is typically produced by manual crosses between selected male-fertile parents or by using genetic male sterility systems. These hybrids are typically selected for single gene traits that unambiguously indicate that a plant is indeed an Fi hybrid that has inherited traits from both presumptive parents, particularly the male parent (since rice normally self- fertilizes). Such traits might include, for example, a semi dwarf plant type, pubescence, awns, or apiculus color. Additional data on parental lines, as well as the phenotype of the hybrid, influence the breeder's decision whether to continue with a particular hybrid cross or an analogous cross, using related parental lines.
- Pedigree breeding and recurrent selection breeding methods are sometimes used to develop cultivars from breeding populations. These breeding methods combine desirable traits from two or more cultivars or other germplasm sources into breeding pools from which cultivars are developed by selling and selection of desired phenotypes. The new cultivars are evaluated to determine commercial potential.
- Pedigree breeding is often used to improve self-pollinating crops. Two parents possessing favorable, complementary traits are crossed to produce F-. plants. An F 2 population is produced by selling one or more Fis. Selection of the superior individual plants may begin in the F 2 (or later) generation. Then, beginning in the F 3 (or other subsequent) generation, individual plants are selected. Replicated testing of panicle rows from the selected plants can begin in the F4 (or other subsequent) generation, both to fix the desired traits and to improve the effectiveness of selection for traits that have low heritability. At an advanced stage of inbreeding (e.g., F 6 or F 7 ), the best lines or mixtures of phcnotypically- similar lines are tested for potential release as new cultivars.
- F 6 or F 7 the best lines or mixtures of phcnotypically- similar lines are tested for potential release as new cultivars.
- Mass and recurrent selection methods can also be used to improve populations of either self- or cross-pollinating crops.
- a genetically variable population of heterozygous individuals is either identified or created by intercrossing several different parents. The best offspring plants are selected based on individual superiority, outstanding progeny, or excellent combining ability. The selected plants are intercrossed to produce a new population in which further cycles of selection are continued.
- Backcross breeding is often used to transfer genes for a simply inherited, highly heritable trait into a desirable homozygous cultivar or inbred line, which is the recurrent parent.
- the source of the trait to be transferred is called the donor parent.
- the resulting plant should ideally have the attributes of the recurrent parent (e.g., cultivar) and the desired new trait transferred from the donor parent.
- individuals possessing the desired donor phenotype e.g., disease resistance, insect resistance, herbicide tolerance
- backcrosscd to the recurrent parent.
- the single-seed descent procedure in the strict sense refers to planting a segregating population, harvesting a sample of one seed per plant, and using the one-seed sample to plant the next generation.
- the plants from which lines are derived will each trace to different F?. individuals.
- the number of plants in a population declines each generation due to failure of some seeds to germinate or some plants to produce at least one seed. As a result, not all of the F 2 plants originally sampled in the population will be represented by a progeny when generation advance is completed.
- a multiple-seed procedure the breeder harvests one or more seeds from each plant in a population and threshes them together to form a bulk. Part of the bulk is used to plant the next generation and part is put in reserve.
- the procedure has been referred to as modified single-seed descent or the pod-bulk technique.
- the multiple-seed procedure has been used to save labor at harvest, ft is considerably faster to thresh panicles by machine than to remove one seed from each by hand as in the single-seed procedure.
- the multiple- seed procedure also makes it possible to plant the same number of seeds from a population for each generation of inbreeding. Enough seeds are harvested to compensate for plants that did not germinate or produce seed.
- Proper testing should detect any major faults and establish the level of superiority or improvement over current cultivars. In addition to showing superior performance, there must be a demand for a new cultivar or hybrid that is compatible with industry standards or that creates a new market. The introduction of a new cultivar or hybrid may incur additional costs to the seed producer, the grower, processor and consumer for such things as special advertising and marketing, altered seed and commercial production practices, and new product utilization. The testing preceding release of a new cultivar or hybrid should take into consideration research and development costs as well as technical superiority of the final cultivar or hybrid.
- hybrids of, and cuitivars derived from, the herbicide- resistant, long-grain rice cuJtivar designated 'CL 151 a herbicide-tolerant eultivar that has superior lodging, processing, and grain yield characteristics.
- This invention also pertains to methods for producing a hybrid or new variety by crossing the rice variety 'CL151' with another rice line, one or more times.
- any such methods using the rice variety 'CL151' are aspects of this invention, including backcrossing, hybrid production, crosses to populations, and other breeding methods involving 'CL 151.
- Hybrid plants produced using the rice variety 'CL151' as a parent are also within the scope of this invention.
- either parent can, through routine manipulation of cytoplasmic or other factors through techniques known in the art. be produced in a male -sterile form.
- this invention allows for single-gene converted plants of 'CLl 51.
- the single transferred gene may be a dominant or recessive allele.
- the single transferred gene confers a trait such as resistance to insects, one or more bacterial, fungal or viral diseases, male fertility or sterility, enhanced nutritional quality, enhanced processing qualities, or an additional source of herbicide resistance.
- the single gene may be a naturally occurring rice gene or a transgene introduced through genetic engineering techniques known in the art. The single gene also may be introduced through traditional backcrossing techniques or genetic transformation techniques known in the art.
- this invention provides r ⁇ generable cells for use in tissue culture of rice plant 'CL151 .
- the tissue culture may allow for regeneration of plants having physiological and morphological characteristics of rice plant 'CL151' and of regenerating plants having substantially the same genotype as rice plant 'CI.151.
- Tissue culture techniques for rice arc known in the art.
- the rcgenerablc cells in tissue culture may be derived from sources such as embryos, protoplasts, meristematic cells, callus, pollen, leaves, anthers, root tips, flowers, seeds, panicles, or stems.
- the invention provides rice plants regenerated from such tissue cultures. Th e following definitions apply throughout the specification and claims, unless context clearly indicates otherwise:
- Grain yield is measured in pounds per acre, at 12.0% moisture.
- Grain yield depends on a number of factors, including the number of panicles per unit area, the number of fertile florets per panicle, and grain weight per floret.
- Lodging Percent Lodging is a subjectively measured rating, and is the percentage of plant stems leaning or fallen completely to the ground before harvest.
- G Gram Length
- 1000 Grain Wi The weight of 1000 rice grains, measured in grams.
- Hardvest Moisture The percentage moisture in the grain when harvested.
- Plant Height Plant height in centimeters, measured from soil surface to the tip of the extended panicle at harvest
- amylose Percent The percentage of the endosperm starch of milled rice that is amylose. The apparent amylose percent is an important grain characteristic that affects cooking behavior. Standard long grains contain 20 to 23 percent amylose. Rexmont-type long grains contain 24 to 25 percent amylose. Short and medium grains contain 13 to 19 percent amylose. Waxy rice contains zero percent amylose. Amylose values, like most characteristics of rice, depend on the environment. "Apparent” refers to the procedure for determining amylose, which may also involve measuring some long chain amylop ⁇ ctin molecules that bind to some of the amylose molecules. These amylopectin molecules actually act similar to amylose in determining the relative hard or soft cooking characteristics.
- Alkali Spreading Value An index that measures the extent of disintegration of the milled rice kernel when in contact with dilute alkali solution. An indicator of geiatinization temperature. Standard long grains have a 3 to 5 Alkali Spreading Value (intermediate geiatinization temperature).
- Peak Viscosity The maximum viscosity attained during heating when a standardized, instrument-specific protocol is applied to a defined rice flour-water slurry.
- Trough Viscosity The minimum viscosity after the peak, normally occurring when the sample starts to cool.
- Setback 1 is the final viscosity minus the trough viscosity.
- Setback 2 is the final viscosity minus the peak viscosity.
- Viscosity As measured by a Rapid Visco Analyzer, is a new but widely used laboratory instrument to examine paste viscosity or thickening ability of milled rice during the cooking process.
- Allele is any of one or more alternate forms of the same gene. In a diploid cell or organism, the two alleles of a given gene occupy corresponding loci on a pair of homologous chromosomes.
- Backcrossing is a process in which a breeder repeatedly crosses hybrid progeny back to one of the parents, for example, crossing a first generation hybrid Fi with one of the parental genotypes of the Fi hybrid, and then crossing a second generation hybrid F> with the same parental genotype, and so forth.
- Quantitative Trait Loci Quantitative Trait Loci (QTL).” Quantitative trait loci (QTL) refer to genetic loci that to some degree control numerically measurable traits, generally traits that are continuously distributed.
- Regeneration refers to the development of a plant from tissue culture.
- Single Gene Converted (Conversion). Single gene converted (conversion) includes plants developed by backcrossing wherein essentially all of the desired morphological and physiological characteristics of a parental variety are recovered, while retaining a single gene transferred into the variety via crossing and backcrossing. The term can also refer to the introduction of a single gene through genetic engineering techniques known in the art,

- transgenic ⁇ s are herein referred to collectively as "transgen ⁇ s.”
- transgenic plants Over the last 15 to 20 years, several methods for producing transgenic plants have been developed, and the present invention, in particular embodiments, also relates to transformed versions of 'CLl 5 L' [0089] An expression vector is constructed that will function in plant cells.
- Such a vector comprises a DNA coding sequence under the control of or operativeiy iinked to a regulatory element (e.g., a promoter).
- the expression vector may contain one or more such operably linked coding sequence/regulatory element combinations.
- the vector(s) may be in the form of a plasmid, and can be used alone or in combination with other plasmids to provide transformed rice plants.
- Expression vectors commonly include at least one genetic "marker,” operably linked to a regulatory element (e.g.. a promoter) that allows transformed cells containing the marker to be either recovered by negative selection, i.e., inhibiting growth of cells that do not contain the selectable marker gene, or by positive selection, i.e., screening for the product encoded by the genetic marker.
- a regulatory element e.g.. a promoter
- Many commonly used selectable marker genes for plant transformation are known in the art, and include, for example, genes that code for enzymes that raetabolJcally detoxify a selective chemical inhibitor such as an antibiotic or a herbicide, or genes that encode an altered target that is insensitive to such an inhibitor. Positive selection methods are also known in the art.
- a commonly used selectable marker gene for plant transformation is that for neomycin phosphotransferase TT (nptll), isolated from transposon Tn5, whose expression confers resistance to kanamycin. See Fraley et aL, Proc. Nail. Acad. Sd. U.S.A., 80:4803 (1983).
- Another commonly used selectable marker gene is the hygromycin phosphotransferase gene, which confers resistance to the antibiotic hygromycin. See Vanden Elzen et aL, Plant MoL Biol., 5:299 (1985).
- Additional selectable marker genes of bacterial origin that confer resistance to one or more antibiotics include gentamycin acetyl transferase, streptomycin phosphotransferase, aminoglycoside-3'-adenyl transferase, and the bleomycin resistance determinant. Hayford el aL, Plant Physiol., 86: 1216 (1988), Jones el aL, MoL Gen. Genet., 210:86 (1987), Svab et aL, Plant MoL Biol., 14: 197 (1990); Plant MoI. Biol., 7: 171 (1986).
- selectable marker genes confer resistance to herbicides such as glyphosate, glufosinatc, or broxynil. Comai et aL, Nature, 317:741-744 (1985); Gordon-Kamm et aL, Plant Cell, 2:603-618 (1990); and Stalker s aL, Science, 242:419-423 (1988).
- Selectable marker genes for plant transformation of non-bacterial origin include, for example, mouse dihydrofolate reductase, plant 5-enolpyruvylshikimate-3- phosphate synthase, and plant acetolactate synthase.
- Eichholtz et aL Somatic Cell MoL Genet. 13:67 ( 1987); Shah et aL, Science, 233:478 (1986); and Charest et aL, Plant Cell Rep., 8:643 (1990).
- marker genes for plant transformation employs screening of presumptively transformed plant cells, rather than selection for resistance to a toxic substance such as an antibiotic. These marker genes are particularly useful to quantify or visualize the spatial pattern of expression of a gene in specific tissues, and arc frequently referred to as reporter genes because they may be fused to the target gene or regulatory sequence. Commonly used reporter genes include glucuronidase (GUS), galaclosidase, luciferase, chloramphenicol, and acctyJtransfcrase. Sec Jefferson, R. A,, Plant MoL Biol.
- GFP Green Fluorescent Protein
- Genes included in expression vectors are driven by a nucleotide sequence comprising a regulatory element, for example, a promoter.
- a regulatory element for example, a promoter.
- Many suitable promoters are known in the art, as are other regulatory elements that may be used either alone or in combination with promoters.
- promoter refers to a region of DNA upstream from the transcription initiation site, a region that is involved in recognition and binding of RNA polymerase and other proteins to initiate transcription.
- a "plant promoter” is a promoter capable of initiating transcription in plant cells. Examples of promoters under developmental control include promoters that preferentially initiate transcription in certain tissues, such as leaves, roots, seeds, fibers, xylem vessels, tracheitis, or sclerenchyma.
- tissue-preferred Promoters that initiate transcription only in certain tissue are referred to as "tissue-specific.”
- a "cell type” specific promoter primarily drives expression in certain cell types in one or more organs, for example, vascular cells in roots or leaves.
- An “inducible” promoter is a promoter that is under environmental control. Examples of environmental conditions that may induce transcription by inducible promoters include anaerobic conditions or the presence of light. Tissue- specific, tissue -preferred, cell type specific, and inducible promoters are examples of “non-constitutive” promoters.
- a “constitutive” promoter is a promoter that is generally active under most environmental conditions.
- an inducible promoter is operably linked to a gene for expression in rice.
- the inducible promoter is operably linked to a nucleotide sequence encoding a signal sequence that is operably linked to a gene for expression in rice. With an inducible promoter the rate of transcription increases in response to an inducing agent.
- Any suitable inducible promoter may be used in the present invention. See
- a preferred inducible promoter is one that responds to an inducing agent to which plants do not normally respond, for example, the inducible promoter from a steroid hormone gene, the transcriptional activity of which is induced by a glucocorticosteroid hormone. See Schena et al, Proc. Nat L Acad Set., U.S.A. 88:0421 (1991 ).
- a constitutive promoter is operably linked to a gene for expression in rice, or the constitutive promoter is operabiy linked to a nucleotide sequence encoding a signal sequence that is operably linked to a gene for expression in rice.
- Constitutive promoters may also be used in the instant invention. Examples include promoters from plant viruses such as the 35S promoter from cauliflower mosaic virus, Odell et ai, Nature, 313:810-812 (1985), and the promoters from the rice actin gene, McElroy el al.. Plant Cell, 2: 163-171 (1990); ubiquitin, Christensen et ai, Plant MoI. Biol., 12:619-632 (1989) and Christensen et ai, Plant MoI. Biol. 18:675-689 (1992); pEMU, Last et al, Theor.

- Brassica napus ALS3 structural gene (or a nucleotide sequence similar to said Xbal/Ncol fragment), may be used as a constitutive promoter. See PCX Application VVO 96/30530. The promoter from a rice ALS (AHAS) gene may also be used. See the sequences disclosed in PCT Application WO 01 /85970; and U.S. Patent Mo. 6,943,280.
- a tissue-specific promoter is operably linked to a gene for expression in rice.
- tissue-specific promoter is operably linked to a nucleotide sequence encoding a signal sequence that is operably linked to a gene for expression in rice.

Gen, Genetics, 244: 161-168 (1993): or a microspor ⁇ -pref ⁇ rred promoter such as that from apg, Tw ell et ai, Sex. Plant Reproci, 6:217-224 (1993).
- Transport of protein or peptide molecules produced by lransgenes to a subcellular compartment such as a chioroplast, vacuole, peroxisome, glyoxysornc, ceil wall, or mitochondrion, or for secretion into an apoplast is accomplished by opera bly linking a nucleotide sequence encoding a signal sequence to the 5' or 3' end of a gene encoding the protein or peptide of interest.
- Targeting sequences at the 5' or 3' end of the structural gene may determine, during protein synthesis and processing, where the encoded protein is u 1 ti mately compartmen ta lized.
- Agronomically significant genes that may be transformed into rice plants in accordance with the present invention include, for example, the following:
