biostudies-literatureUnknown9(12)Henning PMDistyly is a reproductive system, characterized by the presence of two floral morphs, which promotes outcrossing via physical and biochemical means. In distylous Turnera, the mating type of the S-morph is determined by two genes: YUC6 (male) and BAHD (female). Despite the importance of these S-genes, it is likely that additional genes are involved in the distylous syndrome. Here, we use comparative mass spectrometry analysis to identify differentially expressed proteins in a series of self-compatible mutants and wildtype distylous members of Turnera. Our analysis identified a member of the Glutathione S-transferase family that overwhelmingly correlated with L-morph male mating type.
