title: Positive selection acting on a surface membrane protein of the plant-pathogenic phytoplasmas.
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.
