摘要
随着我国经济的发展和人口的增加,人们对水资源的需求不断增加,许多地区出现不同程度的干旱半干旱现象,土地干旱直接制约着我国农作物的产量。提高农作物的抗旱性是我国农业发展亟待解决的难题。植物内生菌分布于没有外在感染症状的健康植物组织内,并与宿主植物协同进化,其增强宿主植物抗逆性的特性引起了研究者的重视,并使之成为了新的研究热点。主要综述植物内生菌对植物抗干旱能力的影响。
With the development of economy and the increase of population, the demand for water resources continuously increases, thus the varied degrees of arid and semi-arid lands occur in many regions. Soil aridification directly constrains the crop yields. Improving crops’ drought resistance is a pressing issue of agricultural development in China. Endophytes distribute in the healthy plant tissues without external infection symptoms, and co-evolve with the host plant;theirs properties of enhancing the resistance of host plant have captured the attentions from researchers and become a new hotspot. This paper mainly summarizes the effects of endophytes on alleviating drought stress of plants by regulating the osmotic regulation substances, antioxidant capacity and drought-related gene expression of plants.
