The maize sex determination pathway results in the arrest of stamen in ear spikelets and the abortion of pistils in both the tassel spikelets and in the secondary florets of ear spikelets. Arrested stamen cells showed no signs of DNA fragmentation, an absence of CYCLIN B expression, and an accumulation of the negative cell cycle regulator WEE1 RNA.
玉米性别决定途径导致雌穗小穗中的雄蕊停止发育，以及雄穗小穗和雌穗小穗二级小花中的雌蕊败育。停止发育的雄蕊细胞没有DNA片段化的迹象，没有细胞周期蛋白B的表达，并且负性细胞周期调节因子WEE1 RNA积累。
