Avoidance of host recognition by alterations in the repetitive and C-terminal regions of AvrXa7, a type III effector of Xanthomonas oryzae pv. oryzae

, : Avoidance of host recognition by alterations in the repetitive and C-terminal regions of AvrXa7, a type III effector of Xanthomonas oryzae pv. oryzae. Molecular Plant-Microbe Interactions 18(2): 142-149

avrXa7 is a member of the avrBs3/pthA gene family. The gene is a critical type III effector in several strains of X. oryzae pv. oryzae (virulence activity), and in the presence of the Xa7 host gene for resistance, controls the elicitation of resistance in rice (avirulence activity). The ability of strains containing avrXa7 to adapt to the presence of Xa7 in the host population is dependent, in part, on the genetic plasticity of avrXa7.
