Expressions of ECE-CYC2 clade genes relating to abortion of both dorsal and ventral stamens in Opithandra(Gesneriaceae)

Abstract

These results suggest that ECE-CYC2 clade TCP genes are not only functionally conserved in the dorsal stamen repression, but also involved in arresting ventral stamens, a genetic mechanism underlying the establishment of zygomorphy with abortion of both the dorsal and ventral stamens evolved in angiosperms, especially within Lamiales s.l.
