Background Dickeya dadantii (formerly Erwinia chrysanthemi) is an opportunistic plant pathogen that causes soft-rot, wilt, and blight diseases on a wide range of plant species. This bacterial pathogen produces a large battery of pectinases for disassembly of the plant cell wall. D. dadantii catabolizes glucose by a fermentative pathway and reduce nitrates to nitrites. Pectinolytic enzymes produce indole and grow at 36 degrees Celsius. It catabolizes (+)-L-arabinose, myo-inositol, (+)-D-malate, malonate, D-mannose, mucate, saccharate and mesotartrate, but does not catabolize (+)-D-trehalose, methyl a-glucoside, (+)-D-arabitol or sorbitol. It is isolated from soft rot and wilt of a various range of plants, such as maize, pineapple, banana, rice, tobacco, tomato, Brachiaria ruziziensis and Chrysanthemum morifolium, as well as from water. D. dadantii possesses two O-serogroups O:1 and O:6.Strain 3937 is a wild-type strain isolated from Saintpaulia ionantha plants in the early 1980s. It is a widely used model system for studying the molecular basis and regulation of soft-rot pathogenesis. Interestingly sequencing has identified four genes encoding homologs of insecticidal toxins, at least one of which has been shown to be involved in virulence in the pea aphid Acyrthosiphon pisum (adapted from PMID 16517643).
