Overexpressing the lncRNA-encoded micropeptide ANCHOR in rice produces significantly longer and wider lateral roots and enhances drought tolerance, while ANCHOR knockouts show opposite phenotypes.
- Why it matters: Lateral root plasticity is crucial for robust root architecture and water uptake under fluctuating conditions, yet how micropeptides from lncRNAs tune this response remains unclear.
- What they did: The study identified ANCHOR, predominantly expressed in lateral root primordia and plumules, then tested overexpression and knockout lines and used localization and protein-interaction assays to show plastid targeting and direct binding to LL-DAPAT.
- The result: ANCHOR promotes LL-DAPAT dimerization, shifts lysine metabolism to raise tryptophan (an auxin biosynthetic precursor), and thereby alters auxin homeostasis, supporting micropeptides as fine-tuning regulators for drought tolerance.
