摘　　要：Moringa leaf extract(MLE)has been shown to promote beneficial outcomes in animals and plants.It is rich in amino acids,antioxidants,phytohormones,minerals,and many other bioactive compounds with nutritional and growth-promoting potential.Recent reports indicated that MLE improved abiotic stress tolerance in plants.Our understanding of the mechanisms underlying MLE-mediated abiotic stress tolerance remains limited.This review summarizes the existing literature on the role of MLE in promoting plant abiotic stress acclimation processes.MLE is applied to plants in a variety of ways,including foliar spray,rooting media,and seed priming.Exogenous application of MLE promoted crop plant growth,photosynthesis,and yield under both nonstress and abiotic stress conditions.MLE treatment reduced the severity of osmotic and oxidative stress in plants by regulating osmolyte accumulation,antioxidant synthesis,and secondary metabolites.MLE also improves mineral homeostasis in the presence of abiotic stress.Overall,this review describes the potential mechanisms underpinning MLEmediated stress tolerance.
