Effector proteins play an important role in the virulence of plant pathogens such as phytoplasma, which are the causative agents of hundreds of different plant diseases. The plant hosts comprise economically relevant crops such as apples ( Malus × domestica ), which can be infected by ‘ Candidatus Phytoplasma mali’ (P....

‘Candidatus Phytoplasma mali’ Genome Encodes a Protein that Functions as an E3 Ubiquitin Ligase and Could Inhibit Plant Basal Defense
