| 摘 要： | LEAFY(LFY)同源基因存在于所有的陆生植物中,在植物花发育早期表达,并在花发育过程中抑制茎端分生组织的营养生长,调控花分生组织和花器官的形成,使转LFY基因植株提前开花,LFY同源基因与其上下游基因共同调控花发育过程.LFY同源基因的蛋白质结构在不同物种间保守性很高,但它们的表达部位差异很大.该文总结了近年来国内外已经克隆到的LFY同源基因的表达、功能及其在果树、花卉、粮食作物上的应用,以期为植物花发育的深入研究提供参考. |

| Abstract: | LEAFY(LFY) homologous genes were found throughout terrestrial plants.They are the earliest flower meristem identity expressed genes.During the floral development,they could prohibit the vegetative growth of shoot apical meristem and are responsible for the regulation of floral meristem and floral organ development.Analyses of LFY transgenic plants indicated that it could make plants flower earlier.LFY homologous genes regulate the floral development with their upstream genes and downstream genes.A lot of st... |
