Positive selection in AvrP4 avirulence gene homologues across the genus Melampsora

Van der Merwe, Marlien; Kinnear, Mark; Barrett, Luke; Dodds, Peter N; Ericson, Lars; Thrall, P; Burdon, Jeremy J.


Pathogen genes involved in interactions with their plant hosts are expected to evolve under positive Darwinian selection or balancing selection. In this study a single copy avirulence gene, AvrP4, in the plant pathogen Melampsora lini, was used to investigate the evolution of such a gene across species. Partial translation elongation factor 1-alpha sequences were obtained to establish phylogenetic relationships among the Melampsora species. We amplified AvrP4 homologues from species pathogenic...[Show more]
