Sugar metabolism drives shoot branching by repressing BRC1 through miR319-targeted TCP4 in Rosa.
The coupling between sugar availability and shoot branching is well established, yet the underlying molecular mechanisms remain largely unknown. Here, using genome-wide profiling, we characterized the sugar signalling pathways by identifying 10 microRNAs (miRNAs) repressed by glycolysis, the tricarboxylic acid (TCA) cy...
