Chlamydomonas reinhardtii
A mutation at the PFlO locus of the unicellular green alga Chlamydomonas reinhardtii leads to abnormal cell motility. The asymmetric form of the ciliary beat stroke characteristic of wild-type flagella is modified by this mutation to a nearly symmetric beat. We report here that this abnormal motility is a conditional phenotype that depends on light intensity. In the absence of light or under lo...
متن کاملPhototaxis in Chlamydomonas Reinhardtii
Parameters which distinguish phototaxis from random motility in Chlamydomonas reinhardtii have been defined with quantitative assays. The phototactic responses in photosynthetic, mixotrophic, and heterotrophic cultures were highest during exponential growth and declined rapidly as the cultures entered stationary phase. In contrast, random motility was relatively constant throughout growth. Phot...
متن کاملSelenoprotein-Transgenic Chlamydomonas reinhardtii
Selenium (Se) deficiency is associated with the occurrence of many diseases. However, excessive Se supplementation, especially with inorganic Se, can result in toxicity. Selenoproteins are the major forms of Se in vivo to exert its biological function. Expression of those selenoproteins, especially with the application of a newly developed system, is thus very important for studying the me...
متن کاملChemoresponses of Chlamydomonas reinhardtii.
Cells of Chlamydomonas reinhardtii have been found to respond to chemicals in two ways: chemokinesis and chemotaxis. Several amino acids, fatty acids, and inorganic salts can stimulate these responses.
متن کاملCellular asymmetry in Chlamydomonas reinhardtii.
Although largely bilaterally symmetric, the two sides of the unicellular alga Chlamydomonas reinhardtii can be distinguished by the location of the single eyespot. When viewed from the anterior end, the eyespot is always closer to one flagellum than the other, and located at an angle of approximately 45 degrees clockwise of the flagellar plane. This location correlates with the position of one ...
