Synechococcus is a unicellular cyanobacterium that is very wide spread in the marine environment. Its size varies between 0.8 and 1.5 µm. The photosynthetic coccoid cells are preferentially found in surface well lit waters where this bacterium can be very abundant (generally from 1,000 to 200,000 of cells by milliliter). Many freshwater genera of Synechococcus have also been described. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...

The genome ofSynechococcus elongatus strain PCC7002 has a size of 2,7 Mpb, that of the oceanic strain WH8102 is 2.4 Mbp. In biology the genome of an organism is the whole hereditary information of an organism that is encoded in the DNA (or, for some viruses, RNA). ...

Marine unicellular cyanobacteria of the Synechococcus group occupy an important position at the base of the marine food web: they are abundant in the world's oceans and as a result are major primary producers on a global scale and one of the most numerous genomes on earth.
Furthermore, a third of the open ocean isolates of Synechococcus possess a unique type of swimming motility not seen in any other type of microorganism: they propel themselves through seawater at speeds of up to 25 µm/sec in the absence of any demonstrable external organelle.
However, three proteins predicted to be involved in Fe scavenging have been identified, based on similarity, in the genome of Synechococcus WH8102: an Fe binding protein (45% identity to IdiA from freshwater Synechococcus PCC6301), inner membrane channel protein (35% identity to HitB from Haemophilus influenza), and an ATPase (42% identity with SfuC from Serratia marcescens).
