Flavonoid levels rather than soil nutrients is linked with Fusarium community in the soybean [Glycine max(L.) Merr.] rhizosphere under consecutive monoculture

As potent allelochemicals, flavonoids are believed to be associated with the development of soil-borne diseases. Fusarium species infection is responsible for soybean [Glycine max(L.) Merr.] root rot. However, it is uncertain if and how flavonoids influence rhizosphere Fusarium communities under consecutive soybean monoculture. Quantitative real-time PCR and pyrosequencing were used to study the Fusarium community. Spectrophotometric techniques...
