Thalassiosiraceae is a family of diatoms in the order Thalassiosirales. The family of Thalassiosiraceae have the unique quality of having a flat valve face. These diatoms are common in brackish, nearshore, and open-ocean habitats, with approximately the same number of freshwater and marine species.
Unlike Naviculaceae who are symmetrical in shape, some Thalassiosiraceae are tangentially undulate.[citation needed]
Thalassiosiraceae are centric diatoms with fultoportulae (central tube passing through the valve and two or more satellite pores).[2] These structures can often be mistaken for areolae present in many diatom families that can be found in different forms such as those in Navicula or Gomphoneis known as lineolate and punctate areolae.[3]
Model organisms
The species Thalassiosira pseudonana was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing.[4]T.pseudonana was selected for this study because it is a model for diatom physiology studies, belongs to a genus widely distributed throughout the world's oceans, and has a relatively small genome at 34 mega base pairs.
