Thalassiosira is a genus of centric diatoms, comprising over 100 marine and freshwater species. It is a diverse group of photosynthetic eukaryotes that make up a vital part of marine and freshwater ecosystems, in which they are key primary producers and essential for carbon cycling. Thalassiosira is a diverse genus, however one species within the genus, T. pseudonana, has gained particular.

Thalassiosira pseudonana and the heterotrophic alphaproteobacterium Ruegeria pomeroyi form a chemical symbiosis in coculture. The bacteria provide vitamin B12 to the diatoms, which in exchange provide organic nutrients to the bacteria.Thalassiosira is a very large and complex genus, which, as presently construed, contains species with several divergent morphological trends. Although Thalassiosira has not been widely reported as a major component of truly freshwater systems, a number of the morphological types found in the genus are represented in the freshwater flora.The marine diatom Thalassiosira rotula was selected as the model organism for the in vitro studies with diatoms and bacteria. Chapter 3 focused on the development of a co-culture to study mutualistic interactions between the diatom T. rotula and bacteria as well as the generation of an axenic (bacteria-free) culture of the diatom T. rotula. The.
Why Sequence Thalassiosira rotula? Diatoms are responsible for significant amounts of marine primary production. In response to favorable light and nutrient conditions, diatoms rapidly divide and form large blooms. As blooms propagate, nutrients are depleted, growth ceases, and cells sink to the deep ocean. The sinking diatom blooms fuel the biological carbon pump and export carbon from the.
Common West Coast species: T. rotula, T. aestivalis, T. nordenskioldii, T. anguste-lineata. Order: Biddulphiales. Family: Thalassiosiraceae. Click on illustration to enlarge. Description: Well-studied marine genus with over 100 species. Discoid cells are in chains or are embedded in mucilage (i.e. T. subtilis). Chain-forming species are connected by a central organic thread. Numerous spine.
Detection and quantification of Thalassiosira rotula with double specific probe assay. A double specific probe assay was applied to detect and quantify Thalassiosira rotula, a common species of harmful algae bloom, in which a set of oligonucleotide probes targeting 18S rRNA was used.
To examine molecular subdivision in the marine diatom Thalassiosira rotula,variations in rDNA sequence, genome size, and growth rate were examined among isolates collected from the Atlantic and Pacific Ocean basins. Analyses of rDNA included T. gravidabecause morphological studies have argued that T. rotulaand T. gravidaare conspecific.
Here we analyse the transcriptome of the diatom Thalassiosira rotula, isolated from the Gulf of Naples in the Mediterranean Sea, comparing cultures grown in normal condition (CTR) versus cultures grown in conditions of stress such as silica depletion (STRESS). Our analysis shows that this diatom species has the potential to produce new metabolites, i.e. secologanin, polyketides and.

Thalassiosira rotula. Which species? Cell identification from their cytometric curves Purpose: Make the species recognition process automatic. Build a comparison measure between cytometric profiles robust to: - the intra-species variability, - the sensor sensibility. Emiliania huxleyi Phaeocystis globosa The automated classification difficulties: - Inter-species profile variability - Intra.
Fecundity, egg viability and fecal pellet production are reported for Acartia clausi females collected in the Bay of Naples, Italy, from April to October 1992 and fed either with a diatom (Thalassiosira rotula) or dinoflagellate (Prorocentrum minimum) diet, at food saturated conditions. The diatom diet significantly reduced both egg and fecal pellet production as well as hatching success.
