^: Pathogenesis by Pectobacterium carotovorum and the other soft rot bacteria results mostly from the synthesis and secretion of a plethora of exoproteins including plant cell wall-degrading enzymes and type III effectors. A mini-Tn5 transposon mutant of P. carotovorum (KD200) was isolated that is highly increased in activity and transcript levels of extracellular cell wall-degradative enzymes, pectate lyase, polygalacturonase, cellulase and protease. Accordingly, the mutant was more virulent as it macerated more host tissue than its parent. KD200 mutant harbours a Tn5 insertion directly upstream of nssAEcc71, a putative sodium/sulphate symporter gene and member of a family of divalent anion sodium symporters (DASS). The findings reported here suggest that DASS proteins may be involved in soft rot pathogenesis. aref1
