What commonalities do the introns in an araphid pennate diatom of the genus Psammoneis have with the two previously annotated diatom species, Thalassiosira pseudonana and Phaeodactylum tricornutum?

Diatoms are an understudied group of algae and are responsible for a significant amount of Earth’s primary productivity. A great way to study the diversity of different diatom species is through genomics and bioinformatics.
