Abstract:

This invention relates to polynucleotide sequences encoding a gene that can confer resistance to the plant pathogen , 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 , 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 and resistant to stalk rot.
