Rapid genetic diversification and high fitness penalties associated with pathogenicity evolution in a plant virus.

Molecular biology and evolution - 1 Apr 2011

Abstract excerpt

Under the gene-for-gene model of host-pathogen coevolution, recognition of pathogen avirulence factors by host resistance factors triggers host defenses and limits infection. Theory predicts that the evolution of higher levels of pathogenicity will be associated with fitness penalties and that the cost of higher pathogenicity must be much smaller than that of not infecting the host. The analysis of pathogenicity...
