Erwinia carotovora ssp. carotovora (Ecc) is a Gram-negative enterobacterium that causes soft rot in potato and other plants. The main virulence factors, secreted extracellular enzymes, degrade the plant cell wall, leading to plant tissue maceration. Extracellular enzymes, cellulases, proteases and pectinolytic enzymes are subject to complex regulatory networks including quorum sensing, two-comp...
