Ostreococcus lucimarinus

Taxonomy: Eukaryota; Viridiplantae; Chlorophyta; Prasinophyceae; Mamiellales; Ostreococcus

Introduction

Three different ecotypes or potential species have been defined for Ostreococcus, based on their adaptation to light intensity. O. lucimarinus is adapted to high light intensities and corresponds to surface-isolated strains. The second (RCC141) has been defined as low-light and includes strains from deeper in the water column. The third (O. tauri) corresponds to strains isolated from a coastal lagoon and can be considered light-polyvalent. We are involved in genome annotation of all three ecotypes and in the comparative analysis of Ostreococcus sp that will help to understand niche differentiation in unicellular eukaryotes and evolution of genome size in eukaryotes.
