摘要: 植物成花转变是高等植物发育过程中的一个非常重要的环节,是在遗传和环境两种因素共同作用和相互协调下完成的。经过对模式植物拟南芥和其他有花植物成花途径的多年研究,现已探明6条开花诱导途径控制植物成花,包括自主促进途径、光周期途径、春化作用途径、赤霉素途径、碳水化合物诱导和成花抑制途径。本文就这6条植物成花途径的机制作简要概述,以期为今后从生理和分子水平调控植物成花奠定基础。

Abstract: In higher plants, flowering transition represents a crucial node from the vegetative stage to the reproductive stage in plant life cycle. This process is controlled by both genetic and environmental factors. The molecular regulating mechanisms of flowering pathways have been studied extensively in Arabidopsis thaliana and several other flowering plants. There are six pathways involved in flowering control, including autonomous pathway, vernalization pathway, photoperiod pathway, gibberellin pathway, carbohydrates induction, and repression pathway. This review summarizes recent progresses on regulating mechanism of flowering transition of anthophyta, and lays the foundation for future floral control of physiology and molecular biology research.
