Salt stress can seriously affect the growth and development of maize (Zea mays L.), resulting in a great yield loss. Melatonin (MT), an indole hormone, is potential enhancer plant tolerance against salt stress. However, complex mechanisms MT application enhancing are still unclear. Herein, three-leaf seedlings salt-susceptible P138 its salt-resistant ethyl methane sulfonate (EMS)-104 mutant were cultured with or without 150 μM under 0 100 mM Na2CO3 treatments for seven days, to systematically explore response exogenous improving maize. The results showed that triggered escalation reactive oxygen species production, enhanced multiple antioxidant enzymes’ activities, impaired cellular membrane permeability, inhibited photosynthetic pigment accumulation, ultimately undermined vigor prowess seedlings. While suitable counteracted detrimental impacts on seedlings’ capacity, seedling length net rate EMS-104 increased by 5.5% 18.7%, 12.7% 54.5%, respectively. Quantitative real-time PCR (qRT-PCR) analysis further activated expression levels enzyme-related genes (Zm00001d025106, Zm00001d031908, Zm00001d027511, Zm00001d040364) biosynthesis-related (Zm00001d011819 Zm00001d017766) both stress; they then formed interaction network gene expression, physiological metabolisms, phenotype changes influence To sum up, these observations underscore alleviate injury seedlings, which may provide new insights investigating regulation enhance resistance.
