Correction to: Function identification of miR159a, a positive regulator during poplar resistance to drought stress.

Correction clarifies the functional role of miR159a as a positive regulator in poplar's drought resistance, emphasizing its importance in plant stress responses.

• Why it matters: Understanding miR159a's role is crucial for developing drought-tolerant trees, addressing the gap in knowledge about microRNA functions in poplar stress adaptation.
• What they did: The authors revisited their previous findings, providing updated insights into miR159a's regulatory mechanisms during drought stress in poplar.
• The result: This correction refines the understanding of miR159a's function, enabling more accurate strategies for enhancing drought resilience in poplar and related species.
