Plant genes that confer resistance to strains of Magnaporthe grisea having AVR CO39 cultivar specificity gene

摘要

Plant pathogen resistance gene (s) present in rice cultivar CO39 and other plant species is disclosed. The locus is referred to as Pi-CO39(t) and confers resistance to strains of the plant pathogen, Magnaporthe grisea (causal agent of rice blast and other plant diseases), having a corresponding AVR1 CO39 avirulence gene. Also disclosed are methods of using the resistance gene and its encoded products for improving resistance of plants to this pathogen.
