Query: NC_004129:5481629 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_010475:420978 Synechococcus sp. PCC 7002, complete genome
Lineage: Synechococcus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria
General Information: The cyanobacterium Synechococcus sp. PCC 7002 (formerly known as Agmenellum quadruplicatum strain PR-6) was originally isolated in 1961 by Chase Van Baalen from an onshore, marine mud flat sample derived from fish pens on Maguyes Island, La Parguera, Puerto Rico. The organism grows in brackish (euryhaline/marine) water and is unicellular but tends to form short filaments of two to four cells during exponential growth at the temperature optimum of 38 degrees C. The strain is extremely tolerant of high light intensities and has been grown at light intensities equivalent to two suns. This unique combination of physiological and genetic properties have long made this strain an important model system to studies of the oxygenic photosynthetic apparatus, the regulation of carbon and nitrogen metabolism, and other aspects of cyanobacterial physiology and metabolism.
