摘要:

开花是植物从营养生长到生殖生长的一个重要转折点。花启动的时机对生殖生长的成功至关重要。开花时间受内在因子和环境因子的共同调节。通过对拟南芥的分子遗传学研究,确定至少存在4条调控开花时间的信号途径,即光周期途径、春化途径、自主途径和赤霉素途径。本文以拟南芥 (Arabidopsis thaliana) 为主要研究对象简要综述了近年来在开花时间调控领域的研究进展。

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.
