Marine diatoms are important primary producers that thrive in diverse and dynamic environments. Through the processes of carbon fixation and photosynthesis, diatoms play a major role in the flux of atomspheric carbon dioxide in oceans [3]. The nuclear genome of T. pseudonana is 34.5 million bp, accounting for a predicted total of 11,242 protein-encoding genes and encodes 24 pairs of chromosomes, totaling 34.5 Mb. Thalassiosira pseudonana (thaps) is a relatively large diatom that resides all over in the world’s oceans. T. pseudonana diatoms display a unique combination of metabolic processes including genes for nitrogen fixation, the urea cycle, carbon fixation, iron uptake, and photosynthesis [3]. Vol. 4 October 2004. The mechanism by which carbon dioxide is transferred to Rubisco during the first step of carbon fixation remains unknown, but the decarboxylating enzymes necessary for the delivery of carbon dioxide to Rubisco are found in the cytoplasm [3]. Not present in any other eukaryotic photoautotrophs, T. pseudonana contains all enzymes necessary for a complete urea cycle. Both glycolysis and gluconeogenesis, are completely localized to the cytoplasm [3]. The influence of this higher variability on the antenna complex organization is still under debate. In diatoms like the model organism Thalassiosira pseudonana, the number of expressed Lhc genes is higher than in organisms of the green lineage (Teramoto et al., 2001), with 11 Lhcf, 14 Lhcr, and five Lhcx gene products (Armbrust et al., 2004).

Thalassiosira pseudonana (thaps) is a relatively large diatom that resides all over in the world’s oceans. Summary Diatoms are widespread in aquatic ecosystems where they may be limited by the supply of inorganic carbon. The optimal temperature for the growth and photosynthesis of T. pseudonana is 25 °C (Claquin et al., 2008), temperature below this can lead to decrease in cellular enzymatic reaction, and lower the efficiency of stress-associated responses and metal detoxification process to protect the algal cell against Cu toxicity. 2.Nelson, DM, Treguer, P, Brezinski MA, Leynaert, A, Queginer, B. Rate of net photosynthesis at pH 7 of Thalassiosira pseudonana grown at 20 000 ppm CO 2 (closed circles) and then switched to 50 ppm CO 2 for 6 h (open circles) or 12 h (triangles).The experimental data were fitted to a slightly modified Michaelis–Menten equation that took into account the compensation point for dissolved inorganic carbon (DIC); parameters are given in Table 1. Analysis of the genome of T. pseudonana reveals that diatoms absorb red and blue light, but not green light [3]. 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. Chlorophyll a per cell decreased under elevated CO 2 and the rates of photosynthesis and respiration decreased significantly under higher levels of CO 2.
