The identity of floral organs in Arabidopsis thaliana is determined by homeotic genes, which are expressed in specific regions of the developing flower. The initial activation of homeotic genes is accomplished at least in part by the products of two earlier acting genes with overlapping functions. These are the floral meristem-identity genes LEAFY and APETALA1. The requirements of LEAFY and APETALA1 activity vary for different homeotic genes.
拟南芥花器官的身份由同源异型基因决定，这些基因在发育中的花的特定区域表达。同源异型基因的最初激活至少部分是由具有重叠功能的两个早期作用基因的产物完成的。这些是花分生组织-身份基因 LEAFY 和 APETALA1。不同的同源异型基因对 LEAFY 和 APETALA1 活性的要求不同。
