| 摘 要： | 综合介绍了高等植物花发育的特点、开花诱导途径、花/花序分生组织形成、花器官发育的分子生物学研究。高等植物的开花诱导有四个促进开花的途径:光周期途径、春化途径、自主途径和赤霉素途径。这些途径通过某些整合基因共同调控植物的开花转换,如FT、LFY、SOC1和FLC等。在花/花序分生组织形成过程中,LFY、AP1等基因发挥着重要作用,它们是花/花序分生组织特异基因。花器官的发育由A、B、C、D、E等五类基因控制,它们调控着花萼、花瓣、雄蕊、心皮的发育。

| Abstract: | This thesis mostly presents the characteristics of flower development and the research on molecule biology of flowering induction way,the formation of flower / inflorescence meristem,floral organ development in higher plant.There are four flowering induction pathways of promoting flowering,which include photoperiodic pathway,vernalization pathway,autonomous pathway and GA pathway.These pathways jointly regulate flowering transition with some integrated genes,such as FT,LFY,SOC1,FLC and so on.Some genes play very important roles in the formation of flower / inflorescence meristem,such as LFY,AP1,etc,which are flower / inflorescence meristem specific genes.The development of floral organs is controlled by A,B,C,D and E genes.These genes regulate the development of sepal,petal,stamen and carpel. |
