A calcium-dependent ergosterol mutant of Saccharomyces cerevisiae.

abstract：:The influence of the DNA repair gene PSO3 on photoactivated psoralen-induced meiotic recombination, gene conversion, reverse mutation, and on survival, was assayed in diploid strains of Saccharomyces cerevisiae homozygous for the wild-type or the pso3-1 mutant allele. Sporulation was normal in the pso3-1 diploid. Wild...
