Biogeneration and Secretion of Sex Pheromones in Female Gametes of Marine Algae.

1. (1R（1 S，2S）-hormosirene和ectocarpene是首次从日本产褐藻C. bullosa，大疱草S. lomentaria，Scytosiphon sp.，和A. japonicus2.（北海道）分泌的性引诱剂为外碳烯，而分泌的性引诱剂为（1 R，2 R）-hormosirene。龙苔属（Yamaguchi）。这是发现同一属的雌配子分泌不同的引诱剂.种间配子的交叉反应。与Scytosiphon sp.或C. bullosa的（1 S，2S）-hormosirene的绝对构型，而C. bullosa和S. lomentaria. 4.雌配子体释放至沉降过程中性引诱剂的酶促产生。bullosa，大疱草S. lomentaria和A.在雌配子细胞中首次证实了这一点。雌配子定居后分泌性引诱剂吸引雄配子。

1.(1R,2R)-Hormosirene, (1S,2S)-hormosirene and ectocarpene were first identified from female gametes of Japanese marine brown algae: C. bullosa, S. lomentaria, Scytosiphon sp., and A. japonicus.2. Scytosiphon sp. (Hokkaido)secreted ectocarpene as the sex-attractant, whereas (1R,2R)-hormosirene for S. lomentaria (Yamaguchi). This is a discovery that female gametes in the same genus secrete different attractants.3. Inter-genus cross-reactions of the gametes of A. japonicus with Scytosiphon sp. or C. bullosa,reflects the absolute configuration of (1S,2S)-hormosirene of A.japonicus: the (1R,2R)-hormosirene from C. bullosa and S. lomentaria.4. Enzymatic productions of sex-attractants during release to settling of the female gametes of C. bullosa,S. lomentaria and A. japonicus were first proved in the female gamete cells. The female gametes secrete sex-attractants for the male gamete-attraction after the settling.
