WebNov 17, 2024 · Among the flowering-time genes, MtFTa1, out of the other five family members (MtFTa2 and 3, MtFTb1 and 2, and MtFTc), is the major regulator for floral transition in response to long day and vernalization, though how MtFTa1 functions in flowering regulation is not well understood in Medicago (Laurie et al., 2011; Jaudal et … 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.
WebJul 28, 2024 · The transition from the vegetative to the reproductive stage of growth is a critical event in the lifecycle of a plant and is required for the plant’s reproductive success.
