Methods for making plants resistant to fungal pathogens
This invention relates to polynucleotide sequences encoding genes 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 genes from corn lines carrying said genes into other corn lines that do not carry said genes, in order to make them resistant to Colletotrichum and resistant to stalk rot.
1. A modified plant comprising a first heterologous polynucleotide encoding a Rcg1 polypeptide having at least 90% sequence identity to SEQ ID NO: 3 and a second heterologous polynucleotide encoding a Rcg1b polypeptide having at least 90% sequence identity to SEQ ID NO: 246, and wherein the modified plant has enahanced resistance to Colletotrichum.
2. The modified plant of claim 1 , wherein the first heterologous polynucleotide comprises SEQ ID NO: 2.
3. The modified plant of claim 1 , wherein the second heterologous polynucleotide comprises SEQ ID NO: 245.
4. The modified plant of claim 1 , wherein the modified plant is a maize plant.
