The PtoERF1‐PtomiR393a‐PtoFBL4 module confers drought tolerance via ABA–auxin crosstalk in Populus
PtomiR393a, a drought‐responsive microRNA in Populus tomentosa that mediates crosstalk between ABA and auxin signaling pathways under drought stress is identified, offering new insights into drought tolerance mechanisms in trees and suggest potential strategies to enhance forest tree resilience to water‐deficit conditions.
