中文摘要：

经典的ABC模型成功地解释了模式植物拟南芥和金鱼草因同源异型基因突变而引起的植物花器官的变异。随后,大量花器官特征基因和新突变体的研究不断完善和发展了ABC模型。该文综述了近年来花器官发育分子模型及花器官同源基因的调控机理等方面的最新研究成果,并对未来的研究方向进行了展望,以期为深入了解花发育的分子机理和遗传机制奠定基础。

英文摘要：

The classical ABC model successfully illustrated the molecular mechamsm o＊ tlorai oevetopment in model species,such as Arabidopsis and Antirrhinum. Then,the ABC model was expanded based on new homeotic genes and mutants of floral organ found in other angiosperms. In this review, the different molecular models of floral organ development and the molecular regulation of homeotic genes are summarized and the prospects in this filed are discussed. This study is helpful for understanding the molecular mechanism and genetic basis of the floral development.
