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
