    Abstract:

    Plant metabolites exuded from roots have been identified as a bridge in plant-microbe interaction,and as a signal player in regulating the structure and diversity of soil microbial community.The altered soil microbial community served as feedback to the plant,resulting in promotion of plant growth,development and resistance.In this article,we reviewed recent advances on plant-microbe interaction mediated by plant metabolites,and sketched the category,function and testing method of the secondary metabolites in the above interaction process.Additionally,we investigated how plants developed themselves in order to adapt to the cultivar evolution and the reproduction by regulating their root metabolites,and illuminated the mechanisms of plants recruiting specific or beneficial microorganisms to the rhizosphere to improve their development and therefore alleviate the biotic and abiotic stresses.Furthermore,the"cry for help"strategy that plants recruit beneficial microbes or traits from the environment using a range of chemical stimuli to enhance their resistance was analyzed.This paper provided ideas and theoretical support for the sustainable agricultural development.
