Floral organ determination is best explained by the ABCDE model postulated by genetic studies of Arabidopsis thaliana. Sepals are determined by A and E class genes; petals are determined by A, B, and E; stamens by B, C, and E; and carpels by C and E class genes. A, B, C, and E class gene lineages are known having duplicated several times during the evolution of angiosperms. One of the noted major duplication events occurred in the origin of the early angiosperms, leading to the formation of subgroups of B/C/D/E class. Another one occurred near the basal eudicots and gave rise to further subgroups in A/B/C/D/E class genes among core eudicots. The phylogenetic position of the family Buxaceae is located right where the second major duplication of ABCDE genes might have occurred, which is supported by multiple gene (nuclear 18S rDNA, chloroplast rbcL and atpB) phylogenetic analyses.
目前经由模式植物阿伯芥的研究,建花部器官决定基因的调控,即花萼由A、E 群基因共同决定,花瓣由A、B、E 群基因,雄蕊由B、C、E 群基因,而心皮由C 和E 群基因决定。A、B、C、E 四群基因在被子植物的演化过程中发生过次的复制事件,其中比较重要的一次发生在早期被子植物演化出之时,形成B/C/D/E 群基因的次系群;另一次复制事件则发生在真双子植物基群附近,形成仅於核心真双子植物的A/B/C/D/E 群基因之次系群。
