LNC159c Negatively Regulates Anthocyanin Biosynthesis via miR159c in Malus spectabilis Under Low Nitrogen.

LNC159c negatively regulates anthocyanin biosynthesis via miR159c in Malus spectabilis under low nitrogen conditions.

• Why it matters: Understanding how lncRNAs influence anthocyanin production under nutrient stress can reveal new regulatory mechanisms in plant responses to low nitrogen, which is important for crop improvement.
• What they did: Researchers identified LNC159c as a regulator whose expression decreases under low nitrogen; they used dual-luciferase, GFP detection, Y1H, and overexpression experiments in apple tissues to study its role and interactions with miR159c and MsMYB10.
• The result: Overexpression of LNC159c increased miR159c levels and decreased MsMYB10 expression and anthocyanin biosynthesis, while MsMYB10 overexpression promoted anthocyanin production; these findings suggest LNC159c modulates anthocyanin accumulation by regulating miR159c and MsMYB10 under low nitrogen.
