Abstract excerpt
In plants, large numbers of R genes, which segregate as loci with alternative alleles conferring different levels of disease resistance to pathogens, have been maintained over a long period of evolution. The reason why hosts harbor susceptible alleles in view of their null contribution to resistance is unclear. In rice, a single copy gene, Pi-ta, segregates for 2 expressed clades of alleles, 1 resistant and the...
