Abstract

Flower development is a crucial trait of higher-plant and is controlled by the action of central genetic regulator, FLOWERING LOCUS T (FT); one of the most crucial promoters of the floral transition that encodes the phloem-mobile florigen protein which is an essential plants flowering signal. FT has a conserved PHOSPHATIDYL-ETHANOLAMINE BINDING PROTEIN (PEBP) domain, but its biochemical properties remain uncharacterized. FT transcriptional regulation is the most competent route to control the flowering period in plants. The expression level of FT can be modified by various TFs of different families such as; MYB, MADS-box, NF-Y, SPL etc which can bind to the promoter region of FT. In temperate grasses microRNA (miRNA) and alternative splicing (AS) can cause modulation in FT expression. Determination of the endogenous levels of FTs in plant is a challenging task because it is difficult to raise antibodies which can be used for the mentioned purpose due to more amino acid resemblance of FT homologs. The facts and findings reviewed in this study incorporate the information and progress regarding the role of FT in controlling flower induction. In this review article, we have summarized the general introduction of FT and discussed its molecular mechanism in regulating flower development in plants.
