DAP-seq EIN3

In angiosperms, sex determination results in the formation of separate male and female flowers on either the same (monoecy) or different individuals (dioecy). Andromonoecy, where plants carry both male and perfect bisexual flowers, has evolved independently numerous times and is found in ~ 4,000 species in 33 angiosperm families. Several species in the Cucurbitaceae, including cucumber (Cucumis sativus) and melon (Cucumis melo), have bisexual floral primordia but often have flowers limited to a single sex. Sex determination occurs by the selective arrest of either the male stamen or female carpel during development.
