Abstract

The transition from vegetative to reproductive growth is the major developmental switch in plant life cycle. The timing of flower initiation is critical for a successful reproduction. Flowering is regulated by endogenous and environmental signals. Molecular genetic studies on Arabidopsis thaliana revealed four major flowering pathways: the photoperiod, the vernalization, the autonomous, and the gibberellin pathways. This paper reviews some research progresses in control of flowering time in Arabidopsis.

摘要

从营养生长到生殖生长的转变是植物生命周期中主要的发育转变。开花起始的时间对于成功繁殖至关重要。开花受内源信号和环境信号的调控。对拟南芥的分子遗传学研究揭示了四条主要的开花途径：光周期途径、春化途径、自主途径和赤霉素途径。本文综述了拟南芥开花时间控制方面的一些研究进展。
