中文摘要：
十字花科作物开花主要受低温春化途径、光周期途径、自主途径和赤霉素途径的信号因子调节,但这些开花信号因子均汇集到开花整合子路径,最终调控开花时间。MADS家族在该发育途径中起着至关重要的作用,最近发现AGL18是一个与开花整合子关系密切的MADS家族成员。综述了拟南芥和芥菜等十字花科作物AGL18在开花途径中的作用及其开花调控分子机制,并展望AGL18开花转变调控的研究方向,为十字花科蔬菜的成花转变及产品器官发育等分子调控提供借鉴。
英文摘要：
Flowering time of cruciferous crops is regulated by floral signals of several pathways,such as vernalization pathway,photoperiod pathway,autonomous pathway and gibberellins pathway,which finally integrate into flowering integration pathway to mediate the flowering time delicately.MADS-box factors play a vital role in flowering-time control.Recent studies have revealed that AGL18 is one of MADS family members involved in floral regulation of flowering integration factors.We summarize the biological functions and molecular mechanisms of crucifer AGL18 in flowering pathways in this paper and discuss the future research interests of AGL18 in regulating floral transition.This work provides valuable information for in-depth studies on molecular regulation of the floral transition and edible organ development in cruciferous vegetables.
