Chinese Abstract

花的發育分為開花決定、花的發端和花器官的發育三個階段。植物開花由多條途徑誘導,包括光週期和光質誘導、春化作用、白主途徑、赤黴素誘導、碳水化合物誘導等;植物體本身也存在著開花抑制途徑。各種開花誘導途徑能激活花分生組織特性基因,使莖端分生組織轉變為花分生組織。花器官的發育由器官特性基因決定,這些基因的精確表達需要花分生組織特性基因的激活和多個正、負調節因子的調控;另有一類基因控制著花發育的對稱性。花發育機理的研究具有重要的理論意義和廣泛的應用前景。

English Abstract

Flower development can be distinguished by three phases: flowering determination, flower evocation, and floral organ development. Several pathways regulate the switch from vegetative to reproductive development, including photoperiod, light quality, vernalization, autonomous pathway, gibberellin, and carbohydrates induction, while repression pathways also exist in plants. Distinct inductive pathways can activate the expression of flower meristem identity genes, thus cause the transition from shoot apical meristem to flower meristem. Floral organ development is controlled by floral organ identity genes, whose exact expression was activated by flower meristem identity genes and controlled by various positive and negative regulators. In addition, there is a kind of genes that determine the symmetry of flower. Research on the mechanism of flower development can contribute to the basic theory research as well as later application.
