Query: NC_004129:926479 Pseudomonas fluorescens Pf-5, complete genome
Lineage: Pseudomonas protegens Pf-5; Pseudomonas; Pseudomonadaceae; Pseudomonadales; Proteobacteria; Bacteria
General Information: This strain can suppress the diseases caused by Rhizoctonia solani and Pythium ultimum which affect cotton plants. The production of a number of antibiotics (pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol) as well as the production of siderophores (which may affect the ability of competing organisms to obtain environmental iron) by this strain can inhibit phytopathogen growth such as the above-mentioned fungi. The genome of this organism contains a number of genes, estimated at 5.7 % of the chromosome, that encode proteins that are involved in secondary metabolism. A large number of repeat elements (REP) are also found in the genome in greater numbers than in related Pseudomonas spp.
Subject: NC_012917:833721 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.
