Mitosis in the pennate diatom Surirella ovalis
Mitosis in Surirella is described; this organism displays a number of unusual features including an unorthodox method of chromosome attachment to the spindle, and the differentiation of an extranuclear central spindle from a large spherical organelle named the microtubule center (MC). The MC, present during interphase, breaks down at late prophase as the central spindle is formed. Later, the sp...
متن کاملAntifouling activity of macroalgal extracts on Fragilaria pinnata (Bacillariophyceae): a comparison with Diuron.
The tributyltin-based products and organic biocides which are incorporated into antifouling paints have had a negative impact on the marine environment, and the ban on tributyltin-based antifouling products has urged the industry to find substitutes to prevent the development of fouling on ship hulls. Natural antifouling agents could be isolated from marine resources, providing an alternative o...
متن کاملThe metabolism of organic acids by a marine pennate diatom.
Cocconeis diminuta, a marine benthic diatom, metabolizes acetate and lactate-(14)C. In the light, the major product was lipid, whereas in the dark, CO(2) was the major product. Analysis of proteins synthesized in the presence of acetate or lactate showed that radioactivity was incorporated predominantly into the glutamate family of amino acids and those amino acids related directly to the subst...
متن کاملComparative genomics of the pennate diatom Phaeodactylum tricornutum.
Diatoms are one of the most important constituents of phytoplankton communities in aquatic environments, but in spite of this, only recently have large-scale diatom-sequencing projects been undertaken. With the genome of the centric species Thalassiosira pseudonana available since mid-2004, accumulating sequence information for a pennate model species appears a natural subsequent aim. We have g...
متن کاملThe Diatom Staurosirella pinnata for Photoactive Material Production
A native isolate of the colonial benthic diatom Staurosirella pinnata was cultivated for biosilica production. The silicified cell walls (frustules) were used as a source of homogeneous and structurally predictable porous biosilica for dye trapping and random laser applications. This was coupled with the extraction of lipids from biomass showing potential to fabricate photoactive composite mate...
