摘要： 植物经历生殖生长与营养生长阶段来确保生命周期的顺利完成，适当的开花时机对生长转变至关重要，开花的机制在植物中高度保守，这一机制的核心在于环境和内源性信号对成花素基因FLOWERING LOCUS T (FT)的转录调控。FT蛋白属于一类保守的蛋白家族，是营养生长和生殖生长转变过程的重要遗传因子，在两个生长阶段中都发挥着重要作用，从不同物种的生殖生长和营养生长两个方面综述FT基因的功能、作用机制和调控网络，为理解植物通过整合多种信号产生对环境变化的适应性和精确性，也为围绕植物生殖调控育种目标进行分子遗传改良提供参考。

Abstract: Plants require reproductive growth and vegetative growth to ensure the success of life cycle. It is vital that this developmental process is precisely regulated. Flowering mechanism is highly conserved in plants, the crucial part of it is the transcriptional regulation by signals from both external and internal of the geneFLOWERING LOCUS T (FT), which is known as florigen. FT protein belongs to a highly conserved protein family. Meanwhile, it is also an important factor that both vegetative growth and reproductive growth need. This article introduced the research onFT’s function and mechanism in the two stages, as well as the role of related transcription factors and their regulation network, in an effort to better understand how plants adapt to environmental changes with precision. Additionally, it provided insights for molecular genetic improvements related to plant reproductive regulation in breeding goals.

Key words: florigen;FLOWERING LOCUS T, mechanism, reproductive growth, vegetative growth
