[Blakeslea trispora mutants with a disrupted sexual process].
Three groups of Blakeslea trispora (+) and (-) mutants were obtained and their phenotypical characteristics were studied as well as biochemical changes in the course of mating and the ability to synthesize carotenoids when the sexual process of these mutants was disordered. The first group of mutants synthesized carotenoids at the control level, the second group produced them below the control level, and the third group accumulated less than 1% of carotenoids as compared to the control. The difference in the yields of carotenoids among the three groups of mutants in the mated culture is attributed to the presence (or absence) of the ability to synthesize trisporic acids in them.
