摘　　要：开花是植物从营养生长向生殖生长的转变过程。开花相关基因的表达是实现这一转变的基础,环境因子以及细胞自身的生长状况对这些基因的表达起着调控作用。目前利用模式植物拟南芥、水稻和观赏植物矮牵牛和金鱼草等植物,已了解到光周期信号被植物成熟叶片接受和感知并产生开花信号物质,这种开花物质经过叶片到茎尖的长距离运输,最终引起茎顶端开花起始。对国内外光周期途径植物成花分子机制的研究进展进行综述,旨在为进一步深入研究光周期调控观赏植物成花分子机制提供参考。Flowering is the transition from vegetative growth to reproductive growth in plants.Flowering-related gene expression is the basis for achieving this transition.Environment factors and the growth conditions of plant cells on the expression of these genes play regulatory roles.Now,it has been known that photoperiod stimulation signal was received and apperceived by mature leaves of plants and there are produced flowering signal substances in the mature leaves of plants,and that this kinds of flowering signal substances transports from leaves to the top of stems,and ultimately causes flowering using model plants Arabidopsis,rice and ornamental plants petunia and Antirrhinum.This article reviewed the study progress in the molecular mechanisms of controlling flowering of plants,in order to provide references for further in-depth studies of photoperiodic flowering molecular mechanism of ornamental plants.
