| Research Abstract |
The Closterium peracerosum-strigosum-littorale (C. psl.) complex is a unicellular charophycean alga and their sex pheromones, responsible for the progress of the sexual reproduction, are well characterized. The C. psl. complex is known to be composed of several reproductively isolated mating groups of heterothallic strains. In this study, we assessed the phylogenetic relationships among reproductively isolated mating groups of the C. psl. complex and sex pheromones. Cross-reactivities of sex pheromones among the groups are also analyzed. The existing degree of reproductive isolation can be explained by differences in molecular structures and physiological activities of sex pheromones of these heterothallic mating groups.
