The Photosynthetic Electron Transport Chain of Chlamydomonas reinhardi
Previous studies (l-3) have described the application of mutant strains of Chlamydomonas reinhardi to an investigation of the enzymatic pathway of triphosphopyridine nucleotide reduction during photosynthesis. Two of these mutants, m-116 and ac-1.41, appear to be genetically blocked in the light-dependent Oz-evolving step of photosynthesis. The validity of this conclusion rests on the following...
متن کاملMetabolic control of urea catabolism in Chlamydomonas reinhardi and Chlorella pyrenoidosa.
In the unicellular green alga Chlamydomonas reinhardi (strain y-1), synthesis of the enzymes required for urea hydrolysis is under substrate induction control by urea and under end product repression control by ammonia. Hydrolysis of urea if effected by the sequential action of the discrete enzymes urea carboxylase and allophanate lyase, collectively called urea amidolyase. The carboxylase conv...
متن کاملNutritional 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 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 ...
