Query: NC_009482:822716 Synechococcus sp. RCC307 chromosome, complete genome

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

General Information: Marine Synechococcus and Prochlorococcus are the most abundant photosynthetic organisms on earth and between them account for about half of the world's photosynthesis. RCC307 is an oceanic Synechococcus strain which presents great phylogenetic interest because trees obtained using its 16S RNA gene seem to indicate that it is rooted at the base of the radiation of marine cyanobacteria. This strain was isolated from seawater taken at a depth of 15 meters from the Mediterranean Sea.

Subject: NC_008048:389645 Sphingopyxis alaskensis RB2256, complete genome

Lineage: Sphingopyxis alaskensis; Sphingopyxis; Sphingomonadaceae; Sphingomonadales; Proteobacteria; Bacteria

General Information: Isolated from Resurrection Bay in the Gulf of Alaska. It is a model oligotrophic organism and forms a very small cell size. his genus was created from the Sphingomonas genus on the basis of phylogenetic, phenotypic, and chemotaxonomic characteristics. Sphingopyxis alaskensis is one of the most numerically abundant microbes found in oligotrophic marine waters and is an important contributor of biomass.
