We report the 34 million–base pair draft nuclear genome of the marine diatom Thalassiosira pseudonana and its 129 thousand–base pair plastid and 44 thousand–base pair mitochondrial genomes. Marine Environmental Research 79: 142–151. and Thalassiosira pseudonana rates of respiration decreased more than those of photosynthesis in high‐temperature evolved lineages resulting in a 1.52‐fold and a 5.5‐fold increase in the P/R ratio relative to the short‐term response to high temperature (Fig. 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 … In the model diatom Thalassiosira weissflogii, we explored the effects of varying pCO2 and pH, independently and in concert, on photosynthesis and respiration by incubating samples in water enriched in H2 18O. 2008; 53 : 494–505. Photosynthetic and transcriptional responses of the marine diatom Thalassiosira pseudonana to the combined effect of temperature stress and copper exposure.
Phytoplankton, which includes diatoms, are a huge part of marine food chains, the carbon cycle, and the recycling of oxygen. Description.

Acclimation to elevated carbon dioxide and ultraviolet radiation in the diatom Thalassiosira pseudonana: Effects on growth, photosynthesis, and spectral sensitivity of photoinhibition. Thalassiosira pseudonana, a centric diatom, is widely distributed throughout world's oceans (Armbrust et al., 2004).
The diatom Thalassiosira pseudonana PEPC2 C4-like photosynthesis gene (figure 9) has a slightly lower fractal dimension of 2.00 as compared to Phaeodactylum tricornutum (Figure 3). -2 -1 Proc. In Thalassiosira pseudonana CCMP 1335, our data indicates that the pool of [PSII diss] is small relative to the other pools, although Wu et al. Article PubMed Google Scholar

It was the first chosen eukaryotic marine phytoplankton species for whole genome sequencing (Armbrust et al).

Cells are usually elliptical in valve view. 5c; Table S9). [72] [73] Despite relatively recent evolutionary divergence (90 million years), the extent of molecular divergence between centrics and pennates indicates rapid evolutionary rates within the … The response of marine phytoplankton to the ongoing increase in atmospheric pCO2 reflects the consequences of both increased CO2 concentration and decreased pH in surface seawater.

However, for Synechococcus sp. We report the 34 million–base pair draft nuclear genome of the marine diatom Thalassiosira pseudonana and its 129 thousand–base pair plastid and 44 thousand–base pair mitochondrial … Yang, G. & K. Gao, 2012. They are responsible for ∼20% of global carbon fixation.

Opposite setae of adjacent cells touch near their origin.. Chaetoceros is primarily a marine genus, but there are also accounts of species within inland waters of the United States. Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. T. pseudonana genes show an average of ~1.52 introns per gene as opposed to 0.79 in P. tricornutum, suggesting recent widespread intron gain in the centric diatom.



Similar (1,3)-β-glucan structures were found in the marine diatoms Coscinodiscus nobilis (Percival et al., 1980), Craspedostauros australis, Cylindrotheca fusiformis and Thalassiosira pseudonana (Chiovitti et al., 2004). The genus Chaetoceros were first described by Ehrenberg in 1844.

Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. About the Thalassiosira pseudonana genome Thalassiosira pseudonanais a centric diatom that belongs to the diverse algal group, likely arose from a common secondary endosymbiotic event, involving at least five different genomes. of SPIE Vol. Cells are more or less rectangular in girdle view.

In this work, we show that in the centric diatom Thalassiosira pseudonana the availability of photosynthetic electron acceptors decreases during the two first hours of dark anoxic acclimation and reaches a steady state (up to 48h).

Physiological responses of the marine diatom Thalassiosira pseudonana to increased pCO 2 and seawater acidity.

The mechanisms of carbon concentration in marine diatoms are controversial. Thalassiosira pseudonana (thaps) is a relatively large diatom that resides all over in the world’s oceans.

found evidence that [PSII diss] could be a significant pool in Thalassiosira pseudonana CCMP 1014. Thalassiosira pseudonana is a species of marine centric diatoms.It was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing. They are responsible for ∼20% of global carbon fixation. Limnology and Oceanography .
