Abstract

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 the polynucleotide sequences, which enhance or confer resistance to the plant pathogen Colletotrichum, and processes of making the 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 the gene into other corn lines that do not carry the gene, in order to make them resistant to Colletotrichum and resistant to stalk rot.
