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.

Subject: NC_005125:2366778 Gloeobacter violaceus PCC 7421, complete genome

Lineage: Gloeobacter violaceus; Gloeobacter; ; Gloeobacterales; Cyanobacteria; Bacteria

General Information: This organism was isolated from a calcereous (chalky) rock in Switzerland. Photosynthetic bacterium. This organism is an obligate photoautotroph that lacks thylakoid membranes and probably has its photosynthetic machinery in the cytoplasmic membrane with various components exposed to the periplasm whereas in other cyanobacteria the components are situated in the thylakoid membrane and are exposed to the cytoplasm. This unusual arrangement may be due to the lack of various fatty acids that are found in the thylakoid membrane in other cyanobacteria. It has been predicted that this organism was one of the earliest to diverge from the cyanobacterial line.
