A Photorespiratory Mutant of Chlamydomonas reinhardtii.
A mutant strain of Chlamydomonas reinhardtii, designated 18-7F, has been isolated and characterized. 18-7F requires a high CO(2) concentration for photoautrophic growth in spite of the apparent induction of a functional CO(2) concentrating mechanism in air-adapted cells. In 2% O(2) the photosynthetic characteristics of 18-7F and wild type are similar. In 21% O(2), photosynthetic O(2) evolution ...
متن کاملMutant strains of Chlamydomonas reinhardtii that move backwards only
Mutations at three independent loci in Chlamydomonas reinhardtii result in a striking alteration of cell motility. Mutant cells representing the three mbo loci move backwards only, propelled by a symmetrical "flagellar" type of bending pattern. The characteristic asymmetric "ciliary" type of flagellar bend pattern responsible for forward movement that predominates in wild-type cells is seldom s...
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 کاملEstimate of the spontaneous mutation rate in Chlamydomonas reinhardtii.
The nature of spontaneous mutations, including their rate, distribution across the genome, and fitness consequences, is of central importance to biology. However, the low rate of mutation has made it difficult to study spontaneous mutagenesis, and few studies have directly addressed these questions. Here, we present a direct estimate of the mutation rate and a description of the properties of n...
متن کاملChlamydomonas 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...
