a Directed inhibitory effect of rhizosphere microbial community on F. oxysporum (P = 0.006, n = 3 biologically independent samples). b VOCs-mediated inhibitory effect of rhizosphere microbial com=munity on F. oxysporum (P = 0.006, n = 3 biologically independent samples). c Enrichment analysis of differential genes of culturable microorganisms in rhizosphere of monocropping and rotation. Rich Factor, the ratio of the number of differential genes in the metabolic pathway to the number of all genes annotated to the pathway (n = 3 biologically independent samples). d Abundance of representative genes associated with pathogen inhibition in cultivable microorganisms of monocropping and rotation. TPM, transcripts Per million (P < 0.001, n = 3 biologically independent samples). Each bars represents the mean ± SD. e The relative abundances of OTUs in the monocropping and rotation samples. The blue bars show the relative abundance of monocropping-enriched OTUs in monocropping samples (<0.002% in rotation samples). The red bars show the relative abundance of monocropping-depleted OTUs in rotation samples (<0.002% in monocropping samples). The nine depleted or enriched OTUs with >97% similarity to isolates are shown (n = 3 biologically independent samples). Each bars represents the mean ± SEM. f Effects of peanut root exudates from monocropping and rotation on growth of monocropping-depleted and enriched bacteria (P < 0.001, n = 12 biologically independent samples). OD, optical density. Asterisks above the bars indicate statistically significant differences between treatments based on two-sided tests by Student’s t-test (*P < 0.05, **P < 0.01, ***P < 0.001). Each bars represents the mean ± SD.
