Abstract: Low temperature is one of the critical abiotic stress, which has an adverse effect on plant growth and development. Arbuscular mycorrhizal fungi (AMF), an ancient kind of microorganism in soil, can constitute mutualistic associations with roots through huge mycelium network, to benefit absorbing nutrients from soil and improving plant nutrientional status, hence promoting plant growth and development and improving the low temperature tolerance. The possible mechanisms of AM symbiosis induced plant tolerance to low temperature include (1) activating the host plant's response systems to the environmental changes; (2) triggering the synthesis of biochemical substances from plants and AMF for regulating host plants' response to low temperature. Therefore, this work summarized the physiological and molecular mechanisms of AM induced plant tolerance to low temperature, including water uptake, changes of plasma membrane permeability and ROS scavenging, carbohydrate synthesis and translocation, N and P uptake, and secondary metabolites synthesis, and finally raised some perspectives, to provide scientific basis for further exploring the mechanisms of plant tolerance induction.
