Query: NC_008781:1426285 Polaromonas naphthalenivorans CJ2, complete genome
Lineage: Polaromonas naphthalenivorans; Polaromonas; Comamonadaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Naphthalene-degrading bacterium. Polaromonas naphthalenivorans was isolated from naphthalene-contaminated, freshwater sediment. This organism is capable of aerobic degradation of naphthalene at temperatures of less than 20 degrees C. Naphthalene is a polycyclic aromatic hydrocarbon (PAH). PAHs can be toxic and/or carcinogenic, therefore PAH contamination is of considerable concern.
Subject: NC_004547:1174650 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.
