Diploids of Clock Mutants of CHLAMYDOMONAS REINHARDI.
Diploids constructed from three clock mutants of Chlamydomonas have been analyzed. In the haploid state, these mutations all lengthen the clock period, and they are at separate genetic loci. One is recessive, one dominant, and one is probably incompletely dominant to their respective wild-type alleles.
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 کاملMutants of the biological clock in Chlamydomonas reinhardi.
A genetic analysis of the biological clock in Chlamydomonas reinhardi has been initiated. Of six wild-type strains tested (3 mt(+) and 3 mt(-)), five had periods close to 24 hr whereas one had a 21-hr period. Mutants with altered clock period have been isolated. The periods of 3 of these variant strains are temperature compensated. Genetic crosses involving a long-period mutant suggest that a s...
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...
