ABSTRACT
Objective:To explore the differences in rhizosphere microbial community structure between <italic>Fusarium</italic> wilt-infected and healthy <italic>Chrysanthemum morifolium </italic>plants<italic>.</italic> Method:The rhizosphere soils of diseased and healthy<italic> C. morifolium </italic>plants were sampled and subjected to high-throughput 16S ribosomal DNA (rDNA) and internal transcribed spacer (ITS) sequencing, to identify the microbial community structure including bacteria and fungi. Result:<italic>Fusarium</italic> wilt reduced the bacterial abundance and diversity but had no significant effect on fungal alpha-diversity.The proportions of Acidobacteria, Gemmatimonadetes, and Nitrospirae in rhizosphere soil of healthy <italic>C.morifolium</italic> plants were higher than those of diseased plants, while the proportions of Proteobacteria and Bacteroidetes were lower(<italic>P</italic><0.05). <italic>Fusarium</italic> fungi accounted for 27.49%, 14.53%, and 11.94% in diseased plants whereas 0.47%, 1.01%, and 0.67% in healthy plants.Pathogenic bacteria <italic>Pectobacterium</italic> and <italic>Dickeya</italic> were enriched in rhizosphere soil of diseased plants. The abundances of nitrifying, detoxifying, and photosynthetic bacteria in rhizosphere soil of healthy plants were higher than those of diseased plants. Conclusion:<italic>Fusarium</italic> wilt reduces the bacterial richness and diversity and triggers the enrichment of massive <italic>Fusarium</italic> fungi, <italic>Pectobacterium</italic>, and <italic>Dickeya</italic>. The proportion of beneficial bacteria in rhizosphere soil of healthy plants is significantly higher than that of diseased plants.
