【 摘 要 】

When plus and minus mating type gametes of Chlamydomonas eugametos were mixed, a rapid transient increase in the amount of cAMP was observed with a maximum at 20 s after the start of the sexual agglutination reaction. The transient increase only occurred within the cells and was also exhibited when cell suspensions of single mating type were presented with isolated flagella of the other mating type. Cyclic AMP-dependent protein kinase and cyclic AMP-phosphodiesterase activities were found in cell homogenates. Since the rise in cAMP concentration preceded all known morphological and physiological changes in the cells that prepare them for fusion, it might be a primary response, induced by sexual agglutination.
