Study IDST000239
Study TitleSexual antagonism in exuded non-volatile metabolites in C. purpureus
Study Typemale - female
Study SummaryThe experimental approach seeks to test for sexual dimorphism in exuded non-volatile metabolites in C. purpureus. The proposed research is creative and original both in its inter-disciplinary approach and its use of a biochemically tractable phenotype to develop a much-needed link between natural selection for sexual dimorphism and the molecular targets of that selection pressure.

Project Title:Sexual antagonism in exuded non-volatile metabolites in C. purpureus
Project Summary:To study the mechanisms responsible for the evolution of sexual dimorphism by identifying sex differences in metabolite production. The PIs recently demonstrated that female mosses produce large numbers of volatile organic compounds (VOCs) that specifically attract microarthropods, and that the presence of these insects increases fertilization rates (ie, a previously unknown fertilization syndrome). Male mosses produce many fewer VOCs, suggesting that VOC production may be costly. Collectively, these results suggest that alleles controlling VOC production may experience ongoing sexual antagonism. Here the PIs propose to generate pilot data to rigorously establish a link between dimorphisms in metabolite profile and its underlying genetic bases in the moss Ceratodon purpureus and related species.
