Research Abstract

An effector gene, VdAve1, was found in the DNA fragment TomR1 that includes sequence specific to race 1 of Verticillium dahliae that is pathogenic on tomato. VdAve1 appeared to be not only an avirulent factor of tomato resistance gene Ve, but also a virulent factor on tomato. However, VdAve1 was not a decisive factor of basic pathogenicity on tomato.
