Pectobacterium carotovorum (Jones 1901) Waldee 1945
causes important soft rot diseases on many plants (bacterial soft rot) and has a worldwide distribution. Crops affected are, among others, potatoes, carrots, as well as vegetables like onions, Brassica crops or tomatoes. P. carotovorum is the type species of the genus Pectobacterium. Members of this genus produce pectolytic enzymes which break down the structural substance pectin in the cell walls, leading to cell death and decay of the tissue. The bacterium is Gram-negative, rod-shaped and motile with a size of 1½-2 x 0.5-0.7 µm. Soft rot diseases develop fast, usually within 2-3 days after inoculation. The symptoms are water-soaked lesions and rapid maceration of the plant tissue. Effective bactericides are currently not available and control through resistant varieties is the common approach.
