Retention of entire genomes in Plasmodiophora brassica represents a previously unrecognized mechanism of balancing selection.

Abstract excerpt

A novel mechanism of balancing selection, a type of natural selection, in root pathogen Plasmodiophora brassicae, is presented. Recent studies have demonstrated that Plasmodiophora brassicae retains entire genomes in its population over time. The proposed mechanism for this retention is suppression of host resistance during infection by a virulent genotype (pathotype). This suppression of resistance provides an...
