Abstract
We analyzed the relationship between the dominant arbuscular mycorrhizal (AM) fungus Funneliformis mosseae and the dominant soybean root rot pathogen Fusarium oxysporum through the pot trials to help overcome obstacles to continuous cropping of soybean and to provide theoretical evidence that can be used to help prevent the reduced production induced by soybean root rot. Using qRT-PCR, we amplified the specific rDNA sequences of F. mosseae and F. oxysporum in soybean roots and rhizosphere soil and quantified the DNA contents of these fungi to determine the relationship between the dominant AM fungus F. mosseae and F. oxysporum. The DNA contents of F. oxysporum differed significantly depending on the presence of F. mosseae in both soybean roots and rhizosphere soil. Specifically, the DNA contents of F. oxysporum were reduced after inoculation with F. mosseae, suggesting that F. mosseae has a negative effect on the growth of F. oxysporum.
