title: Three new yellow loci in Chlamydomonas reinhardtii.
abstract: Three phenotypically 'yellow', mendelian mutants of Chlamydomonas reinhardtii have been isolated and tested for allelism with the yellow mutant y-1 a1 and with each other. The three mutants represent three new yellow loci, two of which are located on linkage group I. Like y-1a, the mutants accumulate protochlorophyllide when grown under dim light, but have a wildtype phenotype when grown in the light. We conclude that the control of light-independent protochlorophyllide reduction is more complex than has been thought previously.
