Secreted effector that increases susceptibility to infection in both monocotyledonous and dicotyledonous plants (PubMed:23441578, PubMed:30856238). Non-catalytic homolog of fungal RNases that binds host RNA and inhibits the degradation of host ribosomal RNA induced by ribosome-inactivating proteins (RIPs), preventing host cell death, an inviable interaction and demise of the fungus (PubMed:30856238). Interacts in planta with the pathogenesis-related protein PR10.
