植物成花转变过程中的分子机理研究

The Molecular Mechanism of Flowering Transition of Plants

植物由营养状态转入生殖状态是发育过程中的重要一步,其转变过程受遗传固子及环境的双重控制,光周期与温度是影响开花诱导的主要环境固子,而植物的同源异型基因参与植物器官内细胞排列方式形成的调拉过程,是拉制花分生组织特异性、花序分生组织特异性和花器官特异性的基础。

The transition between vegetative growth and reproductive growth is a very im- portant step in plant' s development. Both genetic factors and environmental ones control the transition. Photoperiodism and temperature are the main environmental factors that in- fluence floral induction. The homeotic gene not only plays a role in the tegulation of cell ar- rangement in plant' s organ, but also is the base of the floral meristem identity, inflores- cence meristem identity and floral organ identity.
