“…The R environment (version: V3.6.0, http://www.r-project.org/, accessed on 1 May 2022) was used to conduct all statistical analyses. The "vegan" package in R was used to investigate alpha diversity indices such as the Shannon, Simpson, and Chao1 indices [42]. ANOVA was used to investigate how distinct samples' alpha diversity indices varied from one another.…”

“…The DNA of antagonistic bacterial strains was extracted using the Tiangen Bacterial Genome Kit. The extracted genomic DNA of the tested bacterial strains was used as a template for amplifying the 16S rDNA, gyrA, and gyrB genes of the strains using universal bacterial primers [42,43]. After gel electrophoresis to confirm the PCR products, the PCR products of the antagonistic bacterial strains were sent to a sequencing company for sequencing.…”

Zanthoxylum armatum, a significant forest plant in southwestern China, is crucial for preserving soil and water resources. However, the presence of root rot disease has led to plant death, impacting the pepper sector. Effective control measures for this disease are still lacking. Rhizosphere microorganisms play a vital role in plant health by inhibiting plant pathogens and inducing plant resistance. This research aimed to isolate and characterize the pathogen responsible for root rot disease in Z. armatum. Comparative analysis of fungal and bacterial communities in the rhizosphere soil of healthy and diseased plants revealed Fusarium solani as the pathogenic fungus causing root rot disease. Diseased plants had a higher occurrence of Fusarium spp., while disease-free plants had a higher abundance of ecologically beneficial microbial communities that could potentially serve as biocontrol agents. Three bacterial strains (Bacillus subtilis, Bacillus amyloliquefaciens, and Bacillus siamensis) were identified as effective biocontrol agents, inhibiting the growth of the pathogenic fungus F. solani both in vivo and in vitro. This study deepens our understanding of the rhizosphere soil microbial community differences between diseased and healthy Z. armatum, providing potential biocontrol bacteria to enhance plant resistance against root rot disease.
