摘要:

高等植物由营养生长向生殖生长转换的过程称为开花诱导。开花诱导过程由遗传和外界环境两个因素决定, 受错综复杂的网络信号传导途径调控。近年来, 在双子叶模式植物拟南芥中, 开花诱导研究取得了很大进展, 探明了控制开花诱导的4条主要途径(光周期途径、春化途径、自主途径和GA途径)及调控机制。研究也表明, 开花基因在拟南芥、水稻以及其他高等植物之间具有很高的保守性。文章对相关研究的最新进展作一综述, 并指出了目前研究中存在的问题及相应的研究对策。

Abstract:

In higher plant, flowering transition represents a crucial transition from the vegetative stage to the reproductive stage in life cycle. This process is controlled by both endogenous and environmental factors. In Arabidopsis thaliana, four pathways, photoperiod pathway, vernalization pathway, autonomous pathway, and GA pathway were involved in flowering control. These flowering transition pathways are shown to be highly conserved in Arabidopsis and other higher plants including rice (Oryza sativa L.). This review summarizes recent progresses on flowering time control.
