Nutritional Control of Sexuality in Chlamydomonas Reinhardi
1. Cells of Chlamydomonas reinhardi grown in the light or dark on standard medium require an additional exposure to light in the absence of a nitrogen source, in order to become sexually active. As the culture ages, the light requirement decreases. 2. This light requirement is a function of nitrogen depletion, as shown by the observation that cells from cultures grown to maturity on a low nitro...

متن کاملFatty acid synthetase from Chlamydomonas reinhardi.
Cell-free extracts of the unicellular green alga, Chlnmydomonas reinhardi, catalyze the incorporation of acetyl-CoA and malonyl-CoA into long chain fatty acids. The fatty acid synthetase is dependent on added acyl carrier protein for activity, regardless if the cells are grown in the light or in the dark. The major products formed from acetyl-CoA and malonyl-CoA by cells in the light period of ...
متن کاملRecombinants between clock mutants of Chlamydomonas reinhardi.
Mutants affecting the period length of the biological clock in Chlamydomonas reinhardi have been isolated and a start has been made on analyzing the genetics of this system. In four mutants, the long period characteristic seems to be controlled by single genes at separate loci. Crosses between single mutants, as well as crosses involving three or four mutant genes, yielded progeny with periods ...
متن کاملMarker rescue from bleomycin-treated Chlamydomonas reinhardi.
A new method has been developed for gene transfer in eukaryotic cells. Chlamydomonas reinhardi, a unicellular eukaryotic alga, was treated with a lethal dose of bleomycin, an agent that induces chromosome breakage. Bleomycin-treated cells were mated with untreated cells, and the mixture was plated onto selective agar medium. The progeny that arose contained the genetic markers from the untreate...
