FLOWERING LOCUS T encodes a flowering regulator in Arabidopsis thaliana. The FT protein can move between tissues and contributes to the long-distance connection between light-dependent regulation in leaves and reproductive development at the shoot.
Experiments combining tissue-specific expression and grafting supplied evidence for movement of FT protein, separating production of a signal from the site at which development changes. Its roles also extend beyond one flowering response: maternal temperature history in fruits can affect progeny dormancy through this regulatory system.[ref]
