Trehalose 6-phosphate (tre6p) has a dual function as a signal and homeostatic regulator of sucrose levels in plants. In source leaves, tre6p regulates the production of sucrose to balance supply with demand for sucrose from growing sink organs. As a signal of sucrose availability, tre6p influences developmental decisions that will affect future demand for sucrose, such as flowering.
