In flowering plants, DNA–FD–14-3-3 recruits FT to the florigen activation complex both through DNA–FT interactions and by reducing liquid phase condensation of FD protein, which promotes dimerization, leading to FT recruitment.

Reproductive and vegetative development are, together with longevity, crucial processes related to crop yield. In grasses like barley, the shoot apical mer

The maintenance of invariant developmental phenotypes across disparate environments is termed canalization, but few examples of canalization mechanism…

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, 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

Takagi and Lee et al. show that florigen-producing cells express unique transcripts not found in other phloem cells by analyzing transcripts translated into proteins. One such transcript encodes FLP1,...
