The morphological diversity of floral organs can largely be attributed to functional divergence in the MADS-box gene family. Nonetheless, research based on the ABCDE model has yet to conclusively determine whether the AGAMOUS-LIKE 6 (AGL6) subgroup has a direct influence on floral organ development. In the current study, the ABCDE model was used to quantify the contributions of ABCDE and AGL6 genes in the emergence of floral organs.

Background: MADS-box transcription factors function as homo- or heterodimers and regulate many aspects of plant development; moreover, MADS-box genes have undergone extensive duplication and divergence. For example, the morphological diversity of floral organs is closely related to the functional divergence of the MADS-box gene family. B-class genes (such as Arabidopsis thaliana APETALA3 [AP3] and PISTILLATA [PI]) belong to a subgroup of MADS-box genes.

Bryophytes and seedless vascular plants have MADS-box genes but do not have ABCDE or AGAMOUS-LIKE6 (AGL6) genes. ABCDE and AGL6 genes belong to the subgroup of MADS-box genes.
