| 摘 要： | 开花是芸薹属蔬菜作物非常重要的农艺性状，有4条途径调控开花：春化途径，光周期途径，赤霉素途径和自主途径。尽管这４条途径分别受不同的基因网络调节，但最终都汇集到相同的开花路径整合子。本文以模式植物拟南芥为借鉴，综述了芸薹属蔬菜花期调控中春化途径和自主途径关键基因FLC、光周期途径中关键基因CO和赤霉素途径的分子机制，及其在开花信号整合子中的核心调节作用，并对芸薹属蔬菜花期调控的深入研究进行了展望。

| Abstract: | Flowering is an important trait of Brassica vegetables,there are 4 pathways to control flowering:vernalization pathway,photoperiod pathway,gibberellin pathway and autonomous path-way.Although these 4 pathways have different gene regulatory networks,at last gather-together to the same integrator eventually.This paper refers to Arabidopsis thaliana L.to review the molecular mechanisms of key gene FLC in vernalization and autonomous pathways,CO in photoperiod pathway and gibberellin pathway in Brassica vegetables.It also analyzes the regulating functions of the key genes in flowering signal integrators and discusses about the prospects of future research works,according to the present research status. |
