摘要/Abstract

摘要： 植物从营养生长到生殖生长的成花转变是其适应外界环境确保自身繁衍的关键环节,主要受内部调控和外部环境因素的影响,其中光周期是影响植物开花的一个重要因素,目前对其调控开花的分子机制研究也较为深入。本文结合近几年最新研究成果,总结了拟南芥、水稻、高粱和谷子4种植物光周期调控开花的分子机制,在此基础上还介绍了在植物光周期途径中扮演重要角色的一类含有CCT结构域的基因家族,对其不同成员在各个作物中的功能进行了概述,以期为进一步研究CCT基因家族的功能和开展光周期调控开花相关性状的分子育种提供理论基础。

Abstract: Flowering transformation from vegetative growth to reproductive growth is the key link for plants to adapt to the external environments and ensure their reproduction, which is mainly influenced by internal regulation and external environmental factors. Photoperiod is an important factor that affects plant flowering, and the researches on molecular mechanism of photoperiod-regulation flowering were relatively in-depth. In this paper, the molecular mechanism underlying photoperiod-regulation flowering in Arabidopsis, rice, sorghum and foxtail millet was summarized combined with the latest research achievements in recent years. Furthermore, a gene family containing CCT motif that played a key role in photoperiod-regulation flowering pathway was introduced, and the functions of different members of this family in each crop were generalized, to provide theoretical reference for further study on the function of CCT motif-containing gene family and molecular breeding of traits related to photoperiod-regulated flowering.

Key words: photoperiod, flowering, molecular mechanism, CCT gene family
