摘　　要： 主要论述了花发育过程中花器官同源异形基因及其相关基因的调控机理。基因调控是一个复杂的 系统,花同源异形基因既受到上游基因的调控,同时又决定了下游基因的表达。对花发育基因调控的研究,不 仅可以从微观水平了解植物花发育的分子机制,同时对花卉等作物的遗传育种也具有重要的指导意义。 In this review, the genetic and moleculer mechanisms of floral organ development were expounded. The important roles of homeotic genes in the floral organ development were summarized. Because genetic regulation is a complicated system, the homeotic genes are regulated by upstream factors, and control the downstream genes. Therefore,the recent progresses in the molecular regulation of homeotic genes were also discussed.
