FLOWERLOCUS T（FT）是开花的保守启动子，其作用于各种调控途径的下游，包括通过CONSTANS（CO）介导光周期诱导的途径，并且在子叶和叶的脉管系统中表达。一个bZIP转录因子，FD，优先表达在茎尖是FT促进开花所需的。FD和FT通过蛋白质相互作用是相互依赖的伙伴，并在茎尖处起作用，以促进花转变，并通过转录激活花分生组织身份基因APETALA1（AP 1）来启动花发育。FT可能代表开花期的一种长距离信号。
FLOWERING LOCUS T (FT) is a conserved promoter of flowering that acts downstream of various regulatory pathways, including one that mediates photoperiodic induction through CONSTANS (CO), and is expressed in the vasculature of cotyledons and leaves. A bZIP transcription factor, FD, preferentially expressed in the shoot apex is required for FT to promote flowering. FD and FT are interdependent partners through protein interaction and act at the shoot apex to promote floral transition and to initiate floral development through transcriptional activation of a floral meristem identity gene, APETALA1 (AP1). FT may represent a long-distance signal in flowering.
