Embodiments of the disclosure are directed to compositions and methods for enhancing disease resistance in plants. One aspect of embodiments of the disclosure relates to a nucleic acid construct comprising a nucleic acid molecule comprising a Pseudomonas tomato race 1 (Ptr1) polynucleotide, a 5 heterologous DNA promoter sequence, and a 3 terminator sequence, wherein the nucleic acid molecule, the DNA promoter sequence, and the terminator sequence are operatively coupled to permit transcription of the nucleic acid molecule. Methods of imparting disease resistance to a plant and methods of identifying a candidate plant suitable for breeding that displays enhanced disease resistance are also disclosed. Embodiments of the disclosure also include plant cells, plants, and plant seeds including a heterologous Pseudomonas tomato race 1 (Ptr1) polynucleotide.

The present invention relates to clubroot resistance in Brassica. More specifically, the invention relates to the CRT clubroot resistance gene, as well as to methods to create clubroot resistant Brassica plants.

The present invention relates to a cucumber plant (Cucumis sativus L.) that is resistant to Pseudomonas syringae pv. lachrymans, a pathogen that causes angular leaf spot disease in cucumber. The invention further relates to markers linked to the resistance and the use of markers to identify resistant plants. The invention also relates to seed and progeny of such plants and to propagation material derived from such plants and for obtaining such plants. Furthermore, the invention relates to methods for producing, identifying and selecting Pseudomonas resistant cucumber plants, and for producing hybrid plant seed. The invention further relates to the use of a gene and/or QTLs and sequences thereof to identify/select Pseudomonas resistant cucumber plants.

The present invention is in the field of plant breeding and disease resistance. More specifically, the invention includes a method for breeding corn plants containing one or more markers that are associated with resistance to bacteria. The invention further includes germplasm and the use of germplasm containing at least one marker associated with resistance to Bacterial Stalk Rot (BSR) infection for introgression into elite germplasm in a breeding program, thus producing novel BSR resistant germplasm.

The present disclosure provides Brassica oleracea plants exhibiting broad spectrum resistance to Xanthomonas campestris pv. campestris. Such plants may comprise novel introgressed genomic regions associated with disease resistance from Brassica oleracea var. capitata. In certain aspects, compositions, including novel polymorphic markers and methods for producing, breeding, identifying, and selecting plants or germplasm with a disease resistance phenotype are provided.

The present invention relates to clubroot resistance in Brassica. More specifically, the invention relates to the CRT clubroot resistance gene, as well as to methods to create clubroot resistant Brassica plants.

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.

The avirulent strain A257 of the bacterial rice pathogen Burkholderia glumae is an effective priming material to reduce or suppress major diseases in rice and other plants. Protection includes that against bacterial panicle blight, sheath blight, and narrow brown leaf spot. A mutant derivative of A257, A257qsmR, significantly reduces the risk that the priming agent might potentially revert to wild-type pathogenicity.
