Abstract

Phytoplasmas are plant-pathogenic bacteria that cause numerous diseases. This study shows a strong positive selection on the phytoplasma antigenic membrane protein (Amp). The ratio of nonsynonymous to synonymous substitutions was >1 with all the methods we tested. The clear positive selections imply an important biological role for Amp in host-bacterium interactions.
