Schematic view of the flowering pathway in tropical and sub-tropical trees (adapted from Wilkie et al., 2008). Environmental stimuli promote the stabilization of the CO transcription factor, which upregulates FT protein. The FT protein is synthesized mainly in leaf tissue and transported by the phloem to the shoot apical meristem (SAM). In the SAM, FT induces flowering and TFL1 represses genes activated by FT. Downstream of FT, SOC1 up-regulates floral meristem identity genes AP1 and LFY. FT may also act independently of SOC1 by inducing AP1 and LFY gene expression. Up-regulation is represented by arrows and down-regulation or inhibition is represented by ‘an inverted T’.
