摘要： The control of flowering time is critical for plant survival, climatic change, and potential yield. Flowering time is a vital agriculture trait studied under both natural and artificial selection. It is controlled by both genetic and environmental cues. Photoperiod (day length) is a key flowering regulating factor due to its relatively high concern in the same geography, while other factors change year over year. Photoperiodic flowering time is controlled by a complex genetic network which is regulated by florigen. Hd3a/FT is florigen in rice which regulates flowering time in rice. Recent molecular genomic advancement revealed how to identify the molecular nature of florigen, its function, expression, and how to diversify its regulatory pathway. In this review paper, we summarize the recent understanding of flowering time regulation mainly focused on rice florigen (Hd3a), its molecular function, expression and diversified photoperiodic regulatory pathways under short days (SD) and long day (LD) conditions.
