Thalassiosira is a genus of centric diatoms, comprising over 100 marine and freshwater species. It is a diverse group of photosynthetic eukaryotes that make up a vital part of marine and freshwater ecosystems, in which they are key primary producers and essential for carbon cycling [1]
Thalassiosira is a diverse genus, however one species within the genus, T. pseudonana, has gained particular significance as the first marine phytoplankton to have its genome sequenced. T. pseudonana has since become a key model organism for studying diatom physiology. The T. pseudonana genome revealed novel genes for intracellular trafficking and metabolism in diatoms.[2] This species was again used to develop methods for genetic manipulation of diatoms [3] and for the study of silica biomineralization.[4]
