Estimating the term…
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.
A process of identifying a corn plant that displays newly conferred or enhanced resistance to Colletotrichum infection, the process comprising detecting in the corn plant alleles of at least two markers, wherein at least one of said markers is on or within the chromosomal interval below UMC2041 and above the Rcg1 gene, and at least one of said markers is on or within the chromosomal interval below the Rcg1 gene and above UMC2200.
A process of identifying a corn plant that displays enhanced resistance to i Colletotrichum infection, the process comprising detecting in the corn plant the presence or absence of at least one marker at the Rcg1 locus, and selecting the corn plant in which the at least one marker is present.
