Pectobacterium (formerly Erwinia) carotovorum is a Gram-negative plant-specific pathogen, causing soft rot disease of various plant hosts and blackleg in potato by degradation of the plant cell wall. P. carotovorum cells colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr for avirulence) through a type III . Perombe-lon and Kelman (1980) referred the main causes of tuber bacterial soft rot to either unsuitable environmental con-ditions during growth or a bad storage state or to both. carotovorum (Syn.
