Thalassiosira pseudonana is a marine diatom, a unicellular photosynthetic alga. A hallmark of diatoms is their intricately patterned silicified cell wall. In contrast to higher plants, diatoms acquired their plastids via secondary endosymbiosis, the merging of a eukaryotic host cell with a eukaryotic unicellular photosynthetic alga. The genome, including the mitochondrial and plastid genomes, was published in 2004. The nuclear genome comprises 34 Mb and about 11,000 predicted protein-coding genes. The plastid genome comprises about 0.13 Mb and 144 predicted protein-coding genes. The mitochondrial genome comprises about 0.04 Mb and 40 predicted protein-coding genes.
