Abstract: The transition from vegetative to reproductive growth is controlled by day length in many plant species. Day length is perceived in leaves and induces florigen, which moves through the phloem to the shoot apex. At the shoot apical meristem (SAM), florigen causes changes in gene expression and promotes flowering. FT protein plays a key role in the transition. This paper provided an overview of the structural and biochemical features of florigen according to recent studies.

Key words: florigen, photoperiod, FT protein, florigen activation complex
