This is one of 2 genomes of unicellular thermophilic Synechococcus isolated and sequenced from the hot spring cyanobacterial mat in Octopus Spring in Yellowstone National Park, USA. The temperature of the mat typically varies between 50 and 70 degrees Celsius. Synechococcus inhabits the 1 mm-thick upper green layer of the mat, embedded in a matrix of exopolymer and a filamentous Chloroflexus/Roseiflexus-type phototrophic bacteria. The cyanobacteria are photosynthetic and respire during the day, and fix N2 at night. Cyanobacteria that fix N2 have so far been know to do so in specialized cells called heterocysts, to protect the very oxygen-sensitive nitrogenase from O2. These are the first organisms identified that can juggle both metabolic tasks within a single cell at high temperatures. For additional information on this organism see; Allewalt J.P., et al., (2006) Appl. Environ. Microbiol. 72:544-550 (PMID 16391090) and Steunou A.-S. et al., (2006) Proc. Natl. Acad. Sci. U.S.A. 103:2398-2403 (PMID 16467157).
