We previously demonstrated that alterations in sugar partitioning affect the expression of genes involved in hormone biosynthesis and responses, including BRANCHED1 (BRC1), resulting in enhanced shoot branching in transgenic Arabidopsis plants overexpressing cyanobacterial fructose-1,6-bisphosphatase-II in the cytosol (AcF). The exogenous treatment of wild-type Arabidopsis plants with sugars showed the same transcript characteristics, indicating that sugars act as a signal for branching. We also found that the reductions induced in BRC1 expression levels in wild-type plants by the sugar treatments were suppressed in the knockout mutant of sugar transporter 1 (stp1-1). Intracellular sugar contents were similar in stp1-1 and wild-type plants following the sugar treatments, suggesting that STP1 acts as a factor for the regulation of shoot branching depending on extracellular sugar contents.
