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.

Therefore, the sand seedling water-retaining inoculation planting method has important practical significance in sand ecological restoration.

Method for promoting growth of sweet sorghum in saline-alkali soil through arbuscular mycorrhizal fungi
ActiveCN107493896AImprove nutritional statusPromote growthFertilising methodsCultivating equipmentsAlkali soilArbuscular mycorrhizal fungi
The invention relates to a method for promoting growth of sweet sorghum in saline-alkali soil through arbuscular mycorrhizal fungi. The method includes the steps of preparing and applying an arbuscular mycorrhizal fungi agent. When the arbuscular mycorrhizal fungi agent is prepared, a mixture of farmland soil and organic fertilizer serves as a substrate, and the organic fertilizer and decomposed products of the organic fertilizer can be used as a fungi protecting agent to have a buffering effect on saline ions in soil around the arbuscular mycorrhizal fungi in the early period when the fungi agent is applied to the saline-alkali soil so as to help the arbuscular mycorrhizal fungi to resist saline-alkali stress; the symbiotic relationship is smoothly formed between the arbuscular mycorrhizal fungi and the sweet sorghum, the mineral nutrition of the sweet sorghum is remarkably improved, the sweet sorghum can be helped to resist saline-alkali stress, and the growth of the sweet sorghum is promoted.
