Lineage: Mesorhizobium ciceri; Mesorhizobium; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Country: Italy; Environment: Host, Rhizosphere, Root nodule, Soil; Isolation: 5 km before Bottida, Sardinia; Temp: Mesophile. Mesorhizobium species are fast-growing rhizobia. Strains generally form nitrogen-fixing nodules on the roots of a restricted range of leguminous plants. Mesorhizobium ciceri nodulates chickpeas.
Subject: NC_012917:3684840 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.
