Abstract
Soil salinization induced by the dual effects of natural environment and human activities is a serious ecological problem globally. Salinization caused osmotic imbalance, ion stress, oxidative damage, and other hazards to plants, leading to retard, reduce biomass and even total crop failure. Arbuscular mycorrhizal fungi (AMF) is a group of beneficial microorganism with wide distribution. AMF can form symbiotic relationship with most plant roots, with ecological significance in various stressed ecosystems. Because of the highly effective antioxidative system in symbionts, AMF could improve plant anti-oxidative response under salt stress and enhance their tolerance to salt stress. Here, we reviewed the research progress of arbuscular mycorrhizal symbiosis in improing plant antioxidative mechanism, including oxidative damage, osmotic regulation, antio-xidant mechanism and bioactive molecules. Finally, research prospects were proposed to provide theoritical support for improving plant salt tolerance by mycorrhizal biotechnology.
