Objective
The regulation of plant flowering time is a highly adaptive trait. Plants must integrate a multitude of environmental and internal signals in order to flower at the right time of the year. One of the most important factors regulating flowering time is the length of the day, where some plants, like Arabidopsis, respond to a lengthening of the day in order to flower in the spring. Since the 1930s it has been clear that the day-length regulation of flowering time is controlled by a substance moving from the leaf to the shoot apex where the initiation of flower primordia takes place. This substance was called florigen. However, during the last couple of years several important breakthroughs have occurred for our understanding of the day-length regulation of flowering time which has now lead to the identification of a possible identity of florigen as the mRNA produced by the gene FLOWERING LOCUS T (FT). Using a system allowing heat-shock inducible expression of FT in a single Arabidopsis leaf, we could show that the FT mRNA moves from the leaf to the shoot apex where it induces downstream targets.
We could also show that FT induces other targets in the leaf, including an autoregulation of its own transcription, and that ultimately the endogenous FT gene is also induced in the shoot apex. Together, these data showed that the FT mRNA fulfilled all the criteria associated with the classical florigen molecule, although, at the time we could not exclude that also the FT protein moves. This finding has lead to a completely new view of the mechanism regulating flowering time, and prompts a whole new set of experiments in order to further characterize the activity of FT and the possible regulation of the FT mRNA transport.
