Secreted effector that impairs both plant effector-triggered immunity and pathogen-associated molecular patterns (PAMP)-triggered immunity (PTI) (PubMed:23594295). Suppresses plant cell death as a part of the plant defense responses (PubMed:23594295). Facilitates plant infection by altering the auxin content at the roots penetration points of the of the pathogen (PubMed:19807870, PubMed:23594295). Specifically expressed during the first hours of infection of the host plant (PubMed:19807870, PubMed:23594295). Expression is induced during the appressorium-mediated penetration of host roots and peaks during the penetration process (PubMed:23594295). Expression then declines during early biotrophy, and becomes barely detectable during the invasive growth of the oomycete along the stele, and later during the necrotrophic phase of the infection (PubMed:23594295). The RxLR-dEER motif acts to carry the protein into the host cell cytoplasm through binding to cell surface phosphatidylinositol-3-phosphate. Belongs to the RxLR effector family.
