英文摘要	玉米是雌雄同株异花植物，成为研究植物性分化的重要模式植物。玉米雄花着生在顶生分枝的雄穗上，雌花着生在腋生的不分枝穗上。雌花和雄花发育前期，含有雌、雄蕊原基，表现为两性花发育特征，只是到后期雄花中雌蕊和雌花中雄蕊分别退化败育。雌蕊和雄蕊退化分别与雌性化功能基因和雄性化基因作用有关。最近发现玉米性器官发育还受2个C-功能基因调控。因而C-功能基因分别同雌性化基因和雄性化基因协同作用调控玉米性分化过程。; Maize develops male and female flowers in different locations on the plant.Male flowers develop at the tip of the shoot in the tassel, and female flowers express on the ears, which terminate short branches.The development of male flowers in tassels and female flowers in ears is the result of selective arrest and abortion of the inappropriate organ primordia within a bisexual floral meristem.Genetics analysis has shown that stamen abortion and pistil abortion are under the control of feminizing genes and masculinizing genes.Biochemical and genetic evidence suggests that sexual organ identities in maize are orchestrated by two closely related C function genes, ZAG 1and ZMM 2.The presence of two C function genes, feminizing genes and masculinizing genes in sex determination, raises the possibility that these gene products may also cooperate to regulate programs of sexual differentiation.We present a hypothetical model to account for such cooperative interactions.; 国际科学基金
