The invention relates to a combined restoring method of polycyclic aromatic hydrocarbon contaminated soil, comprising the following restoring steps of: planting lucerne as perennial leguminous plants in the polycyclic aromatic hydrocarbon contaminated soil; inoculating a mixed bacterial inoculum comprising arbuscular mycorrhizal fungi, bacillus and flavobacterium; and meanwhile, adding rhamnolipid as a biosurfactant. By rhizosphere effect generated by plant root exudates, the number and the metabolic activity of soil microorganisms are increased; and by inoculating the arbuscular mycorrhizal fungi, the plant growth is promoted, and the root exudates are increased, thereby increasing the root accumulation of organic pollutants and the number of root soil microorganisms. The inoculated high-efficiency polycyclic aromatic hydrocarbon degrading bacteria use plant root secretions as a carbon source and an energy source and can quickly grow and propagate. The polycyclic aromatic hydrocarbon is stripped from soil grains by the biosurfactant, and the bioavailability and the degradability of the organic pollutants are increased.

The DMI1 gene encodes a protein that is required for the early steps of bacterial and fungal symbioses
InactiveUS20050081262A1Enhanced nitrogenEnhanced phosphorous acquisitionBryophytesSugar derivativesBacteroidesPlant nodule
Mycorrhizal and rhizobial associations represent the two most important symbiotic relationships between higher plants and microorganisms, providing access to otherwise limiting supplies of phosphate and nitrogen, respectively. Although many higher plants are able to establish a symbiotic relationship with arbuscular mycorrhizal fungi, legumes are unusual among plants because they also form associations with nitrogen fixing soil bacteria called rhizobia. This symbiosis requires the production of bacterial signals, “Nod factors” that trigger several key developmental responses in the host plant (Dénarié et al., 1996). The DMI1 gene of the model legume M. truncatula plays a major role both in the early steps of Nod factor signaling and in the establishment of mycorrhizal symbiosis. Dmi1 mutants do not exhibit many of the early responses to Nod factors and are incapable of forming nitrogen fixing root nodules. Here we describe the cloning and preliminary characterization of DMI1. The DMI1 gene encodes a novel protein with low global similarity to ligand-gated cation channels of archaea. The protein is highly conserved in angiosperms and ancestral to land plants. Interestingly a putative A. thaliana DMI1 orthologous gene is expressed in roots. As A. thaliana is unable to establish a mycorrhizal symbiosis, this finding suggests that DMI1 may also exhibit a function that is independent of symbiotic interactions.

The method promotes growth of the tobacco, effectively reduces morbidity and disease index of bacterial wilt of the tobacco, and improves resist of the tobacco on the bacterial wilt.
