How plants use sugar to produce roots

Researchers at Heidelberg University have identified a molecular mechanism controlling root branching in plants, which involves the activity of the target of rapamycin (TOR) protein. The study found that glucose plays a crucial role in forming lateral roots, and TOR acts as a gatekeeper to regulate this process.
