Description
Moritz Göbel's team traced in 2026 how a sugar signal called trehalose 6-phosphate, made in plant veins, steers root growth. The signal mirrors carbon status and helps decide growth, branching, and flowering, but its vein-level control of roots was unclear. By raising or lowering the signal only in veins, and by grafting shoots onto roots, the team separated shoot-driven effects from local root effects.
High vein signal shrank roots, cut root sugars and metabolites, and raised shoot-to-root metabolite ratios, while lowering it did the reverse, with shoot veins as the main driver. Root-made signal also tuned local root growth. Plant scientists get a two-level control story: veins balance carbon between shoot and root, shaping the whole root system.
