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.

植物生长和发育，特别是开花的诱导，受到关键调节剂的严格控制，以响应内源性和环境因素。所述FLOWERING LOCUSŤ（FT）/ TERMINAL FLOWER 1（TFL1的磷脂酰乙醇胺结合蛋白（PEBP）基因）家族是中央的植物发育，特别是开花时间和植物结构的调节。FT，长期寻找的成花素，促进开花，而 TFL1 抑制开花。FT 和 TFL1 之间的平衡通过将分生组织从不确定的生长转换为确定的生长来调节植物结构，反之亦然。最近对广泛植物物种的研究表明，除了它们在开花时间和植物结构中的作用外，FT/TFL1家族基因参与植物发育的各个方面，如竹子种子萌发和马铃薯块茎形成。在这篇综述中，我们简要总结了FT/TFL1家族的进化，并重点介绍了它们在不同物种中的保守和不同功能的最新发现。
