Query: NC_004547:3207776 Erwinia carotovora subsp. atroseptica SCRI1043, complete genome

Lineage: Pectobacterium atrosepticum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain (ATCC BAA-672) is a virulent blackleg isolated from the stem of a potato plant. Causative agent for blackleg and soft rot disease in potatoes. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Both Pectobacterium chrysanthemia and Pectobacterium carotovora cause soft-rot diseases of various plant hosts through degradation of the plant cell walls. 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. Pectobacterium atrosepticum is an environmentally widespread organism that causes blackleg and soft rot disease in potatoes. This organism produces pectolytic enzymes that destroy plant tissue and allow the bacteria to spread.

Subject: NC_014974:404015 Thermus scotoductus SA-01 chromosome, complete genome

Lineage: Thermus scotoductus; Thermus; Thermaceae; Thermales; Deinococcus-Thermus; Bacteria

General Information: This is a thermophilic, facultatively mixotrophic sulfur-oxidizing bacterium. Thermus scotoductus SA-01 was isolated from fissure water in a South African gold mine. This organism is a thermophilic bacterium which was isolated from fissure water in the Witwatersrand Supergroup at a depth of 3.2 km below surface in a South African gold mine. It is a 2.9-billion-year-old formation of low permeability sandstone and shale with minor volcanic units and conglomerates. The ambient temperature of the rock is approximately 60°C. Samples were collected from a freshly mined rock surface and from a water-producing borehole that penetrated 121 m horizontally into the formation at a depth of 3,198 m. T. scotoductus SA-01 is a facultative anaerobe capable of coupling the oxidation of organic substrates to reduction of a wide range of electron acceptors, including nitrate, Fe(III), Mn(IV) or S(0) as terminal electron acceptors.
