| Bacterial wilt, a devastating soil-borne bacterial disease in plant, caused by Ralstonia solanacearum, which has been found to be related with serious yield reduction of sola naceous crops. At present, bacterial wilt is one of the major diseases restricting the production of tomato in China. The problem of linkage between disease-resistant genes to bacterial wilt and genes expressing inferior agronomic traits has not been solved. In addition, the resistance of tomato is mainly quantitative inheritance, which makes it more difficult to breed excellent disease resistant varieties. Plant rhizosphere microorganisms are closely interrelated with bacterial wilt resistance. The rhizosphere microorganisms regulate the immune system of plants and improve the resistance of host plants to R. solanacearum. Conversely, the host plants also affect rhizosphere microbial community composition. Therefore, rhizosphere microorganisms play an important role in the control of tomato bacterial wilt. In the present study, the characteristics of rhizosphere microbial community resistant to bacterial wilt and the factors influencing the formation of the community were summarized. The mechanism of resistance heredity of bacterial wilt of tomato regulated by rhizosphere microorganisms were discussed. In addition, research hotspots in fields of the regulation of tomato bacterial wilt by beneficial rhizosphere microorganisms were prospected. The results can provide a reference for further analyzing the induced resistance mechanism, tomato genetic breeding, the contr ol of bacterial wilt and the rational distribution of tomato varieties. |
