Ostreococcus is a genus of unicellular coccoid or spherically shaped green alga belonging to the class Mamiellophyceae. It includes prominent members of the global picoplankton community, which plays a central role in the oceanic carbon cycle. Ostreococcus is one of the smallest known eukaryotic organisms, about 1 micron in size. It is a Prasinophyte and thus part of the "green" chloroplast lineage that includes land plants. It is found in diverse marine environments. O. lucimarinus is adapted to high light intensities. It is found in the upper, illuminated water column of the ocean. It is unicellular consisting of a single chloroplast and mitochondria. It lacks flagella. JGI has sequenced the genome of O. lucimarinus.
