Plant growth and development, particularly the induction of flowering, are tightly controlled by key regulators in response to endogenous and environmental cues. The FLOWERING LOCUS T (FT)/TERMINAL FLOWER 1 (TFL1) family of phosphatidylethanolamine-binding protein (PEBP) genes is central to plant development, especially the regulation of flowering time and plant architecture. FT, the long-sought florigen, promotes flowering and TFL1 represses flowering. The balance between FT and TFL1 modulates plant architecture by switching the meristem from indeterminate to determinate growth, or vice versa. Recent studies in a broad range of plant species demonstrated that, in addition to their roles in flowering time and plant architecture, FT/TFL1 family genes participate in diverse aspects of plant development, such as bamboo seed germination and potato tuber formation. In this review, we briefly summarize the evolution of the FT/TFL1 family and highlight recent findings on their conserved and divergent functions in different species.
