Genes Involved in Light Control of Sexual Differentiation in Chlamydomonas reinhardtii

Gamete formation requires the sequential action of two extrinsic cues, nitrogen deprivation and blue light. The mutants described here are specifically altered in the light-dependent step. Mutations lrg1, lrg3, and lrg4 overcome this light dependence while mutation lrg2 results in a delayed execution of the light-mediated step. The four mutations are linked. The recessive nature of the lrg1, lrg3, and lrg4 mutations implies that they encode elements of negative control in this light response pathway. Analyses of diploids suggest an interaction between the gene products of the mutated loci with a central role for lrg4. The lrg4 mutation is unique also because it overcomes the light dependence of Chlamydomonas zygote germination when present in homozygous form. These data indicate that there are common components in the signal chains that control gametogenesis and zygote germination.
