The entire genome, including the chloroplast, of the marine centric diatom Thalassiosira pseudonana is being sequenced at the Department of Energy's Joint Genome Institute. Thalassiosira pseudonana was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing because this species has served as a model for diatom physiology studies, and the nuclear genome is relatively small (34 Mbp).
