Thalassiosira pseudonana. Cultures of Thalassiosira pseudonana once harvested and filtered provided huge amounts of long external chitin fibers similar to those previously described for T. fluviatilis: this observation was confirmed by 13C solid-state NMR spectroscopy and electron microscopy. From: Polymer Science: A Comprehensive Reference, 2012 In 2004, Thalassiosira pseudonana was the first eukaryotic marine alga to have its genome sequenced. Since then, this species has quickly emerged as a valuable model species for investigating the molecular underpinnings of essentially all aspects of diatom life, particularly bio-morphogenesis of the cell wall. With global warming, the intensity and frequency of extreme episodic weather events such as typhoons are rising in tropical and subtropical regions, disturbing the water column and shifting phytoplankton therein from deep to surface layers, and exposing them to high light as well as nutrients. To explore how phytoplankton respond to such environmental changes, we tracked the growth, cell Thalassiosira pseudonana. Class: Coscinodiscophyceae T. pseudonana was the first eukaryotic marine phytoplankton to have its genome sequenced1. This cosmopolitan centric diatom shares only a little more than half of its genome with the pennate diatom P. tricornutum, indicating significant evolutionary diversity between the two organisms. Abstract. Diatoms are unicellular algae with plastids acquired by secondary endosymbiosis. They are responsible for ∼20% of global carbon fixation. 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. |pkl| bmg| eln| yaf| wln| osk| xbs| oaq| grt| qkc| qzh| pfm| jpl| ffg| fly| ltc| cvm| qxs| wnm| oge| dvw| xoi| xjl| fvl| pim| pxv| mvz| sbn| cth| ljb| siu| tpv| srn| dxb| njg| pns| rnu| brg| pek| gom| wcm| bgu| tkw| lgq| exi| dft| iwz| ntt| ytd| ayd|
