The central region of the valve face is often bounded by an irregular siliceous ring and may or may not exhibit central fultoportulae. Growth can be limited by changes in concentrations of vitamin B-12, silicon, selenium, zinc, nitrogen, phosphorus, or other vitamins (Guillard et al. Thalassiosira pseudonana was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing. Synchronized growth of T. pseudonana cultures was carried out as previously described (25, 33). CLASS: Coscinodiscophyceae ORDER: Thalassiosirales FAMILY: Thalassiosiraceae GENUS: Thalassiosira Thalassiosiraare a genus of centric diatom and primarily grow in marine waters.

Brieﬂy, exponential-phase cultures of T. pseudonana were harvested by centrifugation and washed with silicon-free ASW(T). Realized: Thalassiosira pseudonana was found to be useful for mariculture because it has a high fatty-acid composition (Volkman et al. II. * HUCs are not listed for areas where the observation(s) cannot be approximated to a HUC (e.g. Kiss, K.T. 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. Harris, A.S.D., L.K. It has revealed novel pathways for silica biosynthesis, which involve uptake of monosilicic acid from the marine environment, intracellular transport to a specialized vesicle, and specialized enzymes and peptides driving silica synthesis . The marine centric diatom 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, the genus Thalassiosira is cosmopolitan throughout the world's oceans, and the genome is relatively small at 34 mega base pairs. This clone was originally collected in 1958 from Moriches Bay (Long Island, New York) and has been maintained continuously in culture.  An engineered form of the diatom has been considered as a potential drug delivery vehicle for cancer treatment with chemotherapy drugs that are poorly soluble in water.. 154: 48â57. This dormant state could give T. pseudonana a competitive advantage over native species, but this has not been specifically researched. Measurements of the spectral ab- sorption and beam attenuation coefficients, cell concentra- tion, and cell size distribution in suspension were used to Effect of CO2 supply and demand on zinc uptake and growth limitation in a coastal diatom.
