Formation and Secretion of Sex-Attractants from Motile Gametes of Marine Algae by Settling.

在龙眼丝虹吸和大柱孢雌配子的分泌物中未检测到龙眼丝虹吸性成熟菌体中的双蝶烯A、C′和D′。Dictyopterene B [(-)-hormosirene]的分泌速率为2.8 × 10^<-20> mol. cell^<-1>。s ^<-1>作为性信息素，来自于丝胞花科、金丝莲和金丝莲的雌性配子。在索达科植物的雌配子中，检测出了双蝶蝶烯B和D′。结果表明，Scytosiphonace ae和Chordariaceae的雌配子分泌物中dictyopterene B的绝对构型为（1R, 2R），分别为66-94%。

Dictyoptelene A, C' and D' in sexually matured thalli of Suytosiphon lomentaria were not detected in the secretion of the female gametes of S. lomentaria and Colpomenia bullosa. Dictyopterene B [(-)-hormosirene] was secreted in a rate of 2.8 x 10^<-20> mol. cell^<-1>. sec^<-1> as a sex pheromone from the settled female gametes of Scytosiphonaceae, S. lomentaria and C. bullosa. With female gametes of Chordariaceae, Analipus japonicus, dictyopterene B and D' were detected. The absolute configuration of dictyopterene B in the secretions from the female gametes of the Scytosiphonace ae and the Chordariaceae were determined to be (1R, 2R) with 66-94% e. e., respectively.
