A fungal extracellular effector inactivates plant polygalacturonase-inhibiting protein
Abstract
Plants produce polygalacuturonase-inhibiting proteins (PGIPs) to counteract cell wall degradation by pathogenic microbes. Here the authors show that Sclerotinia sclerotiorum, a fungal pathogen that causes stem rot disease, secretes a PGIP-inactivating effector to diminish plant resistance.
