Abstract: This disclosure concerns methods and compositions for identifying canola plants that have a blackleg resistant phenotype. Some embodiments concern molecular markers to identify, select, and/or construct blackleg resistant plants and germplasm, or to identify and counter-select plants that are susceptible or have low resistance to blackleg disease. Some embodiments concern molecular markers to identify, select, and/or construct blackleg resistant plants that carry the Rlm7 gene. This disclosure also concerns canola plants comprising a blackleg resistant phenotype that are generated by methods utilizing at least one marker described herein.

Abstract: The present invention is in the field of plant breeding and disease resistance. More specifically, the invention provides a method for breeding cotton plants containing one or more quantitative trait loci that are associated with resistance to Root Knot Nematode (RKN), a disease associated with Meloidogyne incognita. The invention further provides germplasm and the use of germplasm containing quantitative trait loci (QTL) conferring disease resistance for introgression into elite germplasm in a breeding program, thus producing novel elite germplasm comprising one or more RKN resistance QTL.

Abstract: Polynucleotides useful for improvement of plants are provided. In particular, polynucleotide sequences are provided from plant sources. Polypeptides encoded by the polynucleotide sequences are also provided. The disclosed polynucleotides and polypeptides find use in production of transgenic plants to produce plants having improved properties.

Abstract: Polymorphic cotton DNA loci useful for genotyping between at least two varieties of cotton. Sequences of the loci are useful for providing the basis for designing primers and probe oligonucleotides for detecting polymorphisms in cotton DNA. Polymorphisms are useful for genotyping applications in cotton. The polymorphic markers are useful to establish marker/trait associations, e.g. in linkage disequilibrium mapping and association studies, positional cloning and transgenic applications, marker-aided breeding and marker-assisted selection, hybrid prediction and identity by descent studies. The polymorphic markers are also useful in mapping libraries of DNA clones, e.g. for cotton QTLs and genes linked to polymorphisms.

Abstract: The cotton variety ST 5288B2F is disclosed. The invention relates to seeds, plants, plant cells, plant tissue, harvested products and cotton lint as well as to hybrid cotton plants and seeds obtained by repeatedly crossing plants of variety ST 5288B2F with other plants. The invention also relates to plants and varieties produced by the method of essential derivation from plants of ST 5288B2F and to plants of ST 5288B2F reproduced by vegetative methods, including but not limited to tissue culture of regenerable cells or tissue from ST 5288B2F.

Abstract: The present invention relates to methods for breeding cotton plants containing a recombination event such that quantitative trait loci (“QTL”) on chromosome 11 are present, associated with resistance to both root-knot nematode (“RKN”) and reniform nematode (“REN”) infection (“stacked nematode resistance”). The invention further provides germplasm and the use of germplasm containing such stacked nematode resistance as a source of nematode resistance alleles for introgression into elite germplasm in a breeding program, thus producing novel elite germplasm comprising the stacked nematode resistance trait.

Abstract: The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes methods for assaying a location to determine the amount of pest infestation, or assaying a plant for its ability to resist infection, and using this information to make agronomic treatment and/or breeding decisions. The invention also provides methods for breeding cotton plants containing one or more quantitative trait loci that are associated with resistance to reniform nematode infection. The invention further includes germplasm and the use of germplasm containing quantitative trait loci (QTL) conferring reniform resistance as a source of reniform resistant alleles for introgression into elite germplasm in a breeding program, thus producing novel elite germplasm comprising one or more reniform resistance loci.

Abstract: Expressed Sequence Tags (ESTs) isolated from cotton are disclosed. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The disclosed ESTs have utility in the development of new strategies for understanding critical plant developmental and metabolic pathways. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. Sequence homology analyses using the ESTs provided in the present invention, will result in more efficient gene screening for desirable agronomic traits. An expanding database of these select pieces of the plant genomics puzzle will quickly expand the knowledge necessary for subsequent functional validation, a key limitation in current plant biotechnology efforts.
