Query: NC_014171:723155 Bacillus thuringiensis BMB171 chromosome, complete genome
Lineage: Bacillus thuringiensis; Bacillus; Bacillaceae; Bacillales; Firmicutes; Bacteria
General Information: This organism, also known as BT, is famous for the production of an insecticidal toxin. The bacterium was initially discovered as a pathogen of various insects and was first used as an insecticidal agent in the early part of this century. This organism, like many other Bacilli, is found in the soil, where it leads a saprophytic existence, but becomes an opportunistic pathogen of insects when ingested.
Subject: NC_012917:569856 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.
