| Research Abstract |
Florigen was proposed about 70 years ago that produced in the leaves and moves up to shoot apex to induce flowering. In 2007 the molecular nature of florigen was revealed to be a family of FT/Hd3a protein. Hd3a protein itself does not possess any biochemically defined functional motifs thus Hd3a should interact with functional effectors to exert its function. Here, we found TCP transcription factors interact with Hd3a, and functional analysis of these proteins revealed their contribution to flowering.
