Protein and RNA synthesizing activities increased markedly during the mating process and decreased during the maturation stage of zygotes in heterothallic strains of Closterium peracerosum-strigosum-littoale, KAS-4-29 (mating-type minus) and KAS -4-30 (mating-type plus) and a homothallic Closterium acerosum. Different proteins were synthesized at the different stages of the mating process, suggesting that a sequential expression and repression of mating genes occur for the mating-specific protein synthesis during the sexual reproduction.
