A Mechanism For Sex Determination In Dioecious Cultivated Spinach, Nicholas West
Wayne State University Dissertations
While unisexual flowers have evolved repeatedly throughout angiosperm families, the actual identity of sex determining genes has been elusive, and their regulation within populations remains largely undefined. Additionally, sex liability is often observed in unisexual plants and has been correlated to external and internal cues, suggesting that the genes responsible for unisexual morphology are not necessarily segregating but rather differentially regulated. Understanding these processes will be of significant theoretical and agronomical importance.
Cultivated spinach is a dioecious species in which an individual will bear alternative sexual organs. Previous work has identified spinach B class floral organ identity genes, SpAP3 and …
