摘　　要：Nitrogen(N)and phosphorus(Pi)are essential macronutrients that affect plant growth and development by influencing the molecular,metabolic,biochemical,and physiological responses at the local and whole levels in plants.N and Pi stresses suppress the physiological activities of plants,resulting in agricultural productivity losses and severely threatening food security.Accordingly,plants have elaborated diverse strategies to cope with N and Pi stresses through maintaining N and Pi homeostasis.MicroRNAs(miRNAs)as potent regulators fine-tune N and Pi signaling transduction that are distinct and indivisible from each other.Specific signals,such as noncoding RNAs(ncRNAs),interact with miRNAs and add to the complexity of regulation.Elucidation of the mechanisms by which miRNAs regulate N and Pi signaling transduction aids in the breeding of plants with strong tolerance to N and Pi stresses and high N and Pi use efficiency by fine-tuning MIR genes or miRNAs.However,to date,there has been no detailed and systematic introduction and comparison of the functions of miRNAs in N and Pi signaling transduction from the perspective of miRNAs and their applications.Here,we summarized and discussed current advances in the involvement of miRNAs in N and Pi signaling transduction and highlighted that fine-tuning the MIR genes or miRNAs involved in maintaining N and Pi homeostasis might provide valuable sights for sustainable agriculture.
