摘　　要：土壤盐碱化是制约我国农作物产量的主要因素之一。如何增强农作物的抗盐碱特性,已成为我国农业持续高效发展的重大课题。植物内生菌存在于植物内部,在增强植物抗病、抗虫、抗旱等胁迫能力方面具有一定作用。内生菌与植物共生关系对植物的显著影响这一现象引起了国内外学者的广泛关注。主要综述植物内生菌的多样性,并从植物的ROS清除系统、细胞中渗透调节物质、矿质元素吸收以及光合作用等方面来说明内生菌对植物耐盐碱能力的影响。Soil salinization is one of the main factors of restricting crop yields. How to enhance crop resistance to salt and alkali, has become a major issue of sustainable development of agriculture in our country. Endophytes exist within the plant and have important impact on stress resistance, such as disease resistance, insect resistance, drought resistance. The phenomenon of the symbiotic relationship between endophyte and plant has been paid great attention. This paper mainly summarizes the diversity of endophytes and illustrates endophyte improving salt and alkali resistance by ROS scavenging system, osmotic regulation substances, mineral elements absorption and photosynthesis of plant.
