摘要/Abstract

摘要： 开花是植物从营养生长转变为生殖生长的重要时期，而开花调控成为近年来植物分子生物学研究的热点。在目前已有的研究中，调控拟南芥开花的基因网络已经发展成一个包含串扰(Crosstalk)、反馈(Feedback)和冗余(Redundancy)的复杂网络，这个网络通过开花整合子来与其他发育过程紧密结合。以调节开花的遗传途径作为基础，重点讨论了顶端分生组织中的信号积累、花发育的时空调节、开花相关基因在拟南芥开花时间或花发育过程以外的其他过程中的功能，并对开花调控网络的深入研究进行了展望。

Abstract: Flowering is one of the most important phase changes during the vegetative to reproductive growth in the life cycle of higher plants. And in recent years, flowering regulation has become a hot research in plant molecular biology. In current study, the gene regulatory network controlling flowering in Arabidopsis thaliana has grown up to a intricate web of crosstalk, feedback, and redundancy, bound tightly with other developmental processes by “process integrators”. The paper only briefly contextualizes the genetic pathways involved in regulating flowering, and focuses on the integration of signals at the shoot apical meristem(SAM), the spatial-temporal regulation of flower development, and finally functions that floral-related genes have in processes other than flowering time or flower development in A. thaliana. Also we discuss about the prospects of future research works, according to the present research status．

Key words: Flowering gene regulatory networks, Flowering integrators, Integration of signals, Flower development, Spatial-temporal regulation
