Query: NC_010694:63654 Erwinia tasmaniensis, complete genome
Lineage: Erwinia tasmaniensis; Erwinia; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Erwinia tasmaniensis Et1/99 (DSM 17950) was isolated from apple flowers in Tasmania, Australia. Erwinia tasmaniensis has been isolated from apple and pear flowers and bark. This organism is not pathogenic to plants and appears to be a common epiphyte, colonizing plant surfaces.
Subject: NC_012917:4646491 Pectobacterium carotovorum subsp. carotovorum PC1, complete genome
Lineage: Pectobacterium carotovorum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria
General Information: Temp: Mesophile; Habitat: Host. Pectobacterium carotovorum causes soft-rot diseases of various plant hosts through degradation of the plant cell walls. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Pectobacterium colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr - avirulence) through a type III secretion system (Hrp - hypersensitive response and pathogenicity). Avr proteins control host-bacterium interactions, including host range. Expression of the plant cell-wall-degrading enzymes is controlled through a quorum-sensing mechanism that quantifies the number of Pectobacterium bacteria through measurement of the concentration of small molecules (acyl homoserine lactones) produced by Pectobacterium.
