摘要: Sex determination in plants involves a variety of mechanisms. Here, we report the map-based cloning and characterization of the unisexual-flower-controlling gene M. M was identified as a previously characterized putative 1-aminocyclopropane-1-carboxylic acid synthase gene, while the mallele that mutated at a conserved site (Gly33Cys) lost activity in the original enzymatically active allele.
