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 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 کاملDiatoms in cytologic specimens of aquatic animals--Part II, dermal, respiratory, and gastric samples.
Figure 1. Diatoms in cytologic samples of Florida manatees (Trichechus manatus latirostris) in A, C, D, F, G, J–L, bottlenose dolphins (Tursiops truncatus) in B, E, I, and a seahorse (Hippocampus erectus) in H. Wright–Giemsa stain.9100 objective (except F;920). (A) naviculoid benthic diatom; skin contamination of urine sediment; wet mount. (B) Nitzschia sp.; gastric fluid direct smear. (C) Navi...
متن کاملUltrastructure and Membrane Traffic During Cell Division in the Marine Pennate Diatom Phaeodactylum tricornutum
The marine pennate diatom Phaeodactylum tricornutum has become a model for diatom biology, due to its ease of culture and accessibility to reverse genetics approaches. While several features underlying the molecular mechanisms of cell division have been described, morphological analyses are less advanced than they are in other diatoms. We therefore examined cell ultrastructure changes prior to ...
