Homodimerization of Ehd1 Is Required to Induce Flowering in Rice.

Plant physiology - 1 Apr 2016

Cho Lae-Hyeon, Yoon Jinmi, Pasriga Richa, An Gynheung

Abstract excerpt

In plants, flowering time is elaborately controlled by various environment factors. Ultimately, florigens such as FLOWERING LOCUS T (FT) or FT-like molecules induce flowering. In rice (Oryza sativa), Early heading date 1 (Ehd1) is a major inducer of florigen gene expression. Although Ehd1 is highly homologous to the type-B response regulator (RR) family in the cytokinin signaling pathway, its precise molecular...
