This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen Colletotrichum, which causes anthracnose stalk rot, leaf blight and top dieback in corn and other cereals. It further relates to plants and seeds of plants carrying chimeric genes comprising said polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making said plants and seeds. The invention further presents sequences that can be used as molecular markers that in turn can be used to identify the region of interest in corn lines resulting from new crosses and to quickly and efficiently introgress the gene from corn lines carrying said gene into other corn lines that do not carry said gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.

The present invention provides methods of marker assisted selection for high oleic/low linolenic traits in canola and in other oil seed crop species, as well as isolated nucleic acids for use as molecular markers in such methods. In particular, molecular markers and Brassica nucleic acid corresponding to fad2 and fad3 gene mutations are disclosed. The markers of the present invention are highly useful for the direct selection of desirable fad2 and fad3 alleles during marker-assisted trait introgression and breeding. In a one aspect of the embodiment, two single nucleotide polymorphism (SNP) markers are provided which correspond to the alleles. Thus, the present invention advantageously permits one of skill in the art to breed for the molecular markers described herein, or derivatives thereof, rather than breeding for a high oleic/low linolenic phenotype.
