模式植物拟南芥开花时间分子调控研究进展

植物从营养生长到生殖生长的转变是开花发育的关键，在合适的时间开花对植物的生长和繁衍极为重要，植物开花时间的调控对农业生产发展意义重大。植物开花是由遗传因子和环境因子协同调节的一个复杂过程。近年来，对不同植物开花调控的研究，特别是对模式植物拟南芥（Arabidopsis thaliana（L.） Heynh.）的开花调控研究取得了显著进展，已探明开花时间分子调控的6条主要途径分别是光周期途径、春化途径、自主途径、温度途径、赤霉素途径和年龄途径。各遗传调控途径既相互独立又相互联系，构成一个复杂的开花调控网络。本文综述了模式植物拟南芥开花时间调控分子机制相关研究的最新进展，并对未来的研究进行了展望。

Recent research progress on the molecular regulation of flowering time in Arabidopsis thaliana

The transformation of plants from vegetative to reproductive growth is the key to flowering and development.Flowering at the right time is important for plant growth and inheritance.Control of flowering time also plays a crucial role in the development of agricultural production.Plant flowering molecular regulation is a complex synergistic regulation of endogenous and exogenous factors.In recent years,research on flowering control of different plants,especially Arabidopsis thaliana(L.) Heynh.,has made remarkable progress.The mechanism of flowering control mainly involves six major pathways,including the photoperiodic,vernalization,autonomous,temperature,gibberellin,and age pathways.A variety of genetic control channels that are independent and interrelated form a complex flowering network.Here we focused on the latest research progress on the functions of newly identified genes underlying plant flowering.This paper could help to further understand the molecular mechanisms involved in the transition from vegetative to reproductive growth in plants.
