Progress in Endophyte Improving Plant Salt and Alkali Resistance

Abstract

Abstract: 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.

Key words: Endophyte, Salinity-alkalinity stress, Resistance, Plant
