Query: NC_011729:812594 Cyanothece sp. PCC 7424 chromosome, complete genome
Lineage: Cyanothece; Cyanothece; ; Chroococcales; Cyanobacteria; Bacteria
General Information: This strain was isolated from a rice field in Senegal. The genome shows that these cells have the ability to store the products of both photosynthesis (glycogen) and nitrogen fixation (cyanophycin) as intracellular inclusion bodies. Unlike some other Cyanothece strains, Cyanothece 7424 appears to be an obligate autotroph.
Subject: NC_008817:1443983 Prochlorococcus marinus str. MIT 9515, complete genome
Lineage: Prochlorococcus marinus; Prochlorococcus; Prochlorococcaceae; Prochlorales; Cyanobacteria; Bacteria
General Information: This strain was collected from the surface waters of the Equatorial Pacific. Marine cyanobacterium. This non-motile bacterium is a free-living marine organism that is one of the most abundant, as well as the smallest, on earth, and contributes heavily to carbon cycling in the marine environment. This cyanobacterium grows in areas of nitrogen and phosphorus limitation and is unique in that it utilizes divinyl chlorophyll a/b proteins as light-harvesting systems instead of phycobiliproteins. These pigments allow harvesting of light energy from blue wavelengths at low light intensity.
