Secreted effector that suppresses callose deposition, a hallmark of pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI) and renders host plants more susceptible to bacterial infection (PubMed:22072967, PubMed:23734779). Reduces host plant responsiveness to salicylic acid (SA) in haustoriated cells into which host-translocated effectors are delivered (PubMed:25329884). Highly expressed during infection. The RxLR-dEER motif is required for the delivery of the effector to the host cell cytoplasm but does not bind phosphatidylinositol monophosphates. Belongs to the RxLR effector family.
