WebIn the vasculature of leaves, CONSTANS protein is produced only in long days where it acts to promote the expression of FLOWERING LOCUS T (FT). FT protein is then translocated to the meristem where it acts to promote floral induction. Thus a detailed molecular framework for the regulation of flowering time has now been established in Arabidopsis. WebThe phytohormone, GA, also participates in flowering time regulation in long days by regulating FT. •. Multiple external and internal factors are integrated into FT transcriptional regulation in leaves. Plants monitor …
