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。

Stamens connivent around gynoecium; filaments free, short; anthers 2-celled, with a distinct membranous connective appendage, lower two with a patent gland at base.

在雌蕊群周围靠合的雄蕊;花丝离生,短;花药2室,具一离生膜质药隔附属物,下部2具一开展的腺体在基部。

Flowers bisexual or bisexual and male; stamens more than 2 × as many as petals; gynoecium 2- to many loculed; ovules 2 to many per locule; fruit with stalked or rarely sessile pulp vesicles; leaves odd-pinnately 3(or 5)-foliolate, digitately 3-foliolate

Five floral organ identity genes of Mussaenda pubescens were cloned and their expression patterns among different organs were detected by RT-PCR. The AP1 homologue, MupAP1, is expressed in enlarged and small sepals, petals and stamens, carpels and fruits; the SEP3 homologue, MupSEP is strongly expressed in all floral organs and weak in leaves as well. Two of the B class gene, AP3 homologue MupDEF and TM6 homologue MupTM6, were detected expressed in all floral organs, however, the other B class gene, MupGLO, homologous to PI, were detected expressed in small sepals, petals and stamens, carpels and fruits, but not in enlarged sepals.
