拟南芥开花时间调控的分子基础

Molecular Basis of Flowering Time Regulation in Arabidopsis

在合适的时间开花对大多数植物的生存和成功繁衍极为重要。开花时间受错综复杂的环境因素和植物自身的遗传因子影响,由开花调控因子所构成的光周期、春化、温度、赤霉素、自主以及年龄等至少6条既相互独立又相互联系的遗传途径调控。该文综述了有关拟南芥(Arabidopsis thaliana)开花时间调控的分子机制的最新研究进展,并对今后的研究进行了展望。

Flowering time is crucial for most plants to successfully survive and reproduce. Both environmental and ge- netic factors can regulate flowering time. The flowering regulators consist of at least 6 closely interlinked but divergent genetic regulation pathways, including photoperiod, vernalization, ambient temperature, gibberellic acid and autonomous pathways. This review summarizes the research progress in the molecular basis of flowering time regulation in Arabidop- sis and prospects for future study.
