Companion cells with high florigen production express other small proteins and reveal a nitrogen-sensitive FT repressor
A distinct subset of leaf companion cells expresses high levels of the florigen gene, and the same cells also produce other possible mobile floral regulators and small proteins.

Florigen in Arabidopsis forms the activation complex at the SAM via multifaceted assembly, with 14-3-3 proteins linking FT and FD to trigger flowering. PMID:41225013, Nature 2025, @Nature https://doi.org/10.1038/s41586-025-09704-6 #Medsky #Pharmsky #RNA #ASHG #ESHG 🧪
Florigen activation complex forms via multifaceted assembly in Arabidopsis | Nature
Florigen, encoded by FT genes, is synthesized in leaves and transported to the shoot apical meristem (SAM) to induce flower development1–3. At the SAM, 14-3-3 proteins are proposed to act as receptors for FT protein and to mediate the indirect interaction between FT and the basic leucine zipper (bZIP) transcription factor FD to form the florigen activation complex (FAC) that activates transcription of flowering genes4–6. Here we demonstrate a different mechanism of FAC assembly, diverse functions for the 14-3-3 proteins within the complex, and an unexpected spatiotemporal distribution of the FAC. We show that FT is not recruited by 14-3-3 alone, but that it interacts with the DNA–FD–14-3-3 complex through two interfaces, one of which binds DNA via the unstructured C terminus of FT. We also find that interaction of 14-3-3 proteins with the C terminus of phosphorylated FD reduces liquid phase condensation of the intrinsically disordered FD protein, allowing it to bind DNA, and that the 1

Unfortunately, however, Chailakhyan did not live to see his theory of a mobile, leaf-derived flowering factor being proven correct in 2007, with 4 simultaneous publications (2 each in @science.org & @currentbiology.bsky.social) showing the FLOWERING LOCUS T (FT) protein to be the mobile factor.
