M真菌和根瘤菌防控植物真菌病害的研究进展

M Fungi andrhizobium could improve host resistance to plant fungal disease and increaseplant production. Effects of AM fungi and rhizobium on the fungal diseases ofplants were summarized based on the literatures published both nationally andinternational. The mechanisms for AM fungi improving plant disease resistance include:improved nutrient status of the host plant, damage compensation, changed root growth and morphology, competitionwith pathogens for colonization sites and host photosynthates,changed microbialin the mycorrhizosphere and activation of plant defense mechanisms. Rhizobiumcan also reduce plant disease incidence,the mechanism may include physiologicaland biochemical changes, change in root growth and morphology and activation ofplant defence mechanisms. The present of the AM fungi and rhizobium couldbatter control plant disease. Suggestions and prospects for study of AM fungiand rhizobium to control plant fungal disease were developed for futureresearch.
