| 摘 要： | 开花是指植物从营养生长转变到生殖生长的生理过程, 是植物个体发育和后代繁衍的中心环节, 既受遗传基础决定,同时又受到温度和光周期等多种环境因素的调控。在拟南芥中, 已经分离了大量的与开花相关的基因, 从遗传学上已初步形成了一个开花调控的网络。组蛋白甲基化是植物发育过程的重要调节方式, 近年来关于其参与开花调控的研究有了重要进展。本文综述了具有代表性的组蛋白H3赖氨酸甲基化修饰参与调控植物开花发育的机制, 提出该研究领域的发展方向和前景。

| Abstract: | Flowering represents a major physiological developmental transition from vegetative to reproductive development in the plant life cycle. It is the central cue in plant development and is determined by the control of both intrinsic genetics and environmental factors such as low temperature and photoperiod. Many genes related to flowering have been isolated in Arabidopsis, and a genetic network of the flowering process has been mapped. Histone methylation plays an important role in the regulation of plant development. Great progress has been achieved with histone modification in regulating flowering. This paper reviews the epigenetic research into histone lysine methylation in plant flowering. We also review new directions and expectations in this research field. |
