高等植物抽穗开花调控的分子网络

Molecular Network of Heading and Flowering Regulation in Higher Plants

抽穗开花是高等植物从营养生长向生殖生长转变的过程,该过程受到众多基因的调控,这些基因又相互作用形成了一个复杂的调控网络。综述了近年来模式植物拟南芥和水稻抽穗开花调控分子机制的研究进展,重点介绍了植物抽穗开花调控的光周期途径、赤霉素途径、自主途径和春化途径,比较了这些途径在拟南芥和水稻中的异同。最后,结合作者对谷子抽穗开花调控分子机制的研究,探讨了未来的研究方向。

Heading and flowering is the transition stage from vegetative to reproductive growth in higher plants, which is regulated by multiple genes. These genes interact with each other and form a complex control network. This paper reviewed the molecular mechanism of heading and flowering regulation in the model plant Arabidopsis thaliana and rice in recent years, mainly focused on the photoperiod pathway, gibberellin pathway, autonomous pathway and vernalization pathway. The similarities and differences in these pathways between Arabidopsis and rice were also compared. Finally, the future research perspectives were discussed based on our research on the heading and flowering regulation in foxtail millet.
