n1_4mer:GRV/n1_4mer:RV = (Global Relative Variance of OU patterns) / (Local Relative Variance of OU patterns)

n0_4mer:D = Distance between local and global OU patterns

n0_4mer:PS = Distance between 2 strands of same DNA molecule

Selected loci indicated by large D, increased GRV associated with decreased RV and moderate increase in PS

NC_007604: Synechococcus elongatus PCC 7942, complete genome

NCBI: NC_007604

Host Lineage: Synechococcus elongatus; Synechococcus; Synechococcaceae; Chroococcales; Cyanobacteria; Bacteria

General Information: This strain is a freshwater organism and is extensively studied due to its circadian clock which controls the expression of upwards of 800 genes during a 24 hour period. These unicellular cyanobacteria are also known as blue green algae and along with Prochlorococcus are responsible for a large part of the carbon fixation that occurs in marine environments. Synechococcus have a broader distribution in the ocean and are less abundant in oligotrophic (low nutrient) regions. These organism utilize photosystem I and II to capture light energy. They are highly adapted to marine environments and some strains have evolved unique motility systems in order to propel themselves towards areas that contain nitrogenous compounds. An obligate photoautotroph, it has been studied extensively by an international research community with respect to acquisition of organic carbon, transport and regulation of nitrogen compounds, adaptation to nutrient stresses, and reponse to light intensity.
