ECE-CYC1 Transcription Factor CmCYC1a May Interact with CmCYC2 in Regulating Flower Symmetry and Stamen Development in <i>Chrysanthemum morifolium</i>.

ABSTRACT:

Background

The attractive inflorescence of Chrysanthemum morifolium, its capitulum, is always composed of ray (female, zygomorphy) and disc (bisexual, actinomorphy) florets, but the formation mechanism remains elusive. The gene diversification pattern of the ECE (CYC/TB1) clade has been speculated to correlate with the capitulum. Within the three subclades of ECE, the involvement of CYC2 in defining floret identity and regulating flower symmetry has been demonstrated in many species of Asteraceae, including C. morifolium. Differential expression of the other two subclade genes, CYC1 and CYC3, in different florets has been reported in other Asteraceae groups, yet their functions in flower development have not been investigated.
