Drought, exacerbated by global warming, poses a significant threat to crop growth and productivity. This study identified a strain of from the rhizosphere of healthy L. plants and evaluated its role in enhancing drought tolerance. The isolated strain effectively colonized plant roots and promoted the growth of L. To investigate its potential, was inoculated into plants under varying drought conditions, and its impact on growth, physiological responses, and drought resilience was assessed. Comprehensive analyses of agronomic traits, physiological parameters, enzyme activities, photosynthetic performance, osmoprotectant levels, and membrane lipid peroxidation revealed that inoculation (light drought with , moderate drought with , and severe drought with treatments) systematically improved plant development and drought resistance. These findings provide valuable insights and lay a foundation for developing innovative biofertilizers to enhance crop drought tolerance and sustainability.
全球变暖加剧了干旱，对作物生长和生产力构成重大威胁。本研究从健康的L.植物根际中鉴定出一种菌株，并评估了其在增强耐旱性方面的作用。分离出的菌株有效地定殖在植物根部并促进了L.的生长。为了研究其潜力，在不同干旱条件下将该菌株接种到植物中，并评估其对生长、生理反应和干旱恢复力的影响。对农艺性状、生理参数、酶活性、光合性能、渗透保护剂水平和膜脂过氧化的综合分析表明，接种该菌株（轻度干旱用，中度干旱用，重度干旱用处理）系统地改善了植物发育和抗旱性。这些发现提供了有价值的见解，并为开发创新型生物肥料以增强作物耐旱性和可持续性奠定了基础。
