Abstract: The PGPB(plant growth-promoting bacterium)presents a promising prospect in agriculture due to its advantages such as inhibiting rhizosphere pathogens,promoting plant growth,and increasing crop production. This paper first summarizes the species of plant growth-promoting rhizobacteria and the promoting mechanisms of involved colonization,and demonstrates the colonization process of rhizobacteria as well as the factors influencing the colonization of bacteria in rhizosphere. Then the paper reviews the detection methods of microorganisms in the colonization of bacteria,including antibiotics marking,immunological methods,and exogenous gene marking methods. Further,the paper discusses high-throughput sequencing technologies widely used in the rhizosphere colonization. Finally,it is concluded that the future researches on interpreting strains in genetic level,gaining microbial community diversity in plant rhizosphere and the functional genes should be of significance to better predict the interaction of PGPB and its host plant,and to apply bio-fertilizers in field.

Key words: colonization, rhizobacteria, growth-promoting, high-throughput sequencing
