| 摘 要： | 高等植物成花是当今发育生物学研究的热点和难点.高等植物的成花诱导过程由自身遗传因子和外界环境因素两方面决定.在已知的成花途径中,光周期途径是研究得较为清楚的一条途径.目前高等植物光周期成花分子机理的研究主要针对拟南芥进行.光周期调控中CONSTANS(CO)是关键基因,它进行光信号和生物钟信号整合,节律性地表达激活FLOWERING LOCUS T(FT)表达,诱导植物开花.在不同的光周期反应的植物中,基因调控成花作用的机理并不完全相同.现就光周期成花的研究进展作简要综述.

| Abstract: | Flowering is currently a hot spot and difficult points of research topic.Photoperiodic control of flowering in plant decides by genetic factor and environment.Studies on photoperiodic control of flowering in plant have been clear-cut in long day plant Arabidopsis.Many research results demonstrated that CONSTANS gene plays a very important role in photoperiodic control,which received the light signal and circadian clock signal to activate FLOWERING LOCUS T(FT) and other genes inducing the flowering.Photoperi... |
