摘　要：

成花诱导是高等植物由营养生长向生殖生长过渡的重要环节。成花诱导过程由内因和外因两个因素决定。近年来, 在对拟南芥、水稻等有花模式植物成花机制的研究中, 已发现植物成花主要受春化、温敏、光周期、赤霉素、自主、成花抑制和年龄7条途径控制。文章简要综述这7条途径相关研究的最新进展, 以期为今后从分子和生理水平调控植物成花诱导提供基础。

Abstract:

Floral induction represents a crucial transition from the vegetative stage to the reproductive stage in higher plants. This process is determined by both environmental and endogenous factors. The regulating mechanisms of flowering pathways have been studied extensively in Arabidopsis thaliana, Oryza sativa and several flowering plants. Seven pathways, vernalization pathway, thermosensory pathway, photoperiod pathway, gibberellin (GA) pathway, autonomous pathway, repression pathway and aging pathway were involved in flowering control. This review summarizes recent progresses in controlled flowering time, and provides a foundation for molecular and physiological research on floral control.
