Replanting disease is a growing problem in intensive agricultural systems. Application of bio-fertilizer containing beneficial microbes contributes to disease suppression and is a promising strategy to control replanting disease. However, the effect of both replanting disease and bio-fertilizer amendment on the assembly of crop microbiota in leaves and roots and their relationships to crop yield and quality remains elusive. In these experiments, roots and leaves of Radix pseudostellariae were collected from different consecutive monoculture and bio-fertilizer amended fields, and the associated microbiota were characterized by bacterial 16S rRNA gene sequencing and quantitative PCR. Consecutive monoculture altered the bacterial community structure and composition and significantly increased the abundance of potential pathogenic Ralstonia and Fusarium oxysporum in leaves and roots. Furthermore, bio-fertilizer application alleviated replanting disease by decreasing the pathogen load, increasing the potential beneficial genera Pseudomonas, Streptomyces, Paenibacillus, and Bradyrhizobium. The proportion of positive correlations in the co-occurrence network of bio-fertilizer application was the highest, implying that bio-fertilizer potentially enhanced ecological commensalism or mutualism of the bacterial community across the two compartments. Structural equation models indicated that bio-fertilizer had a positive and indirect effect on both yield and quality by shaping the leaf microbiota and the root microbiota. Our findings highlight the role of leaf and root microbiota on replanting disease, showing that bio-fertilizer contributes to alleviating replanting disease by improving microbe-microbe interactions.
