Abstract

Abstract: 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.

Key words: endophyte, drought stress, resistance
