Streptomyces aureoverticillatus HN6 was isolated in our previous study and effectively controlled banana Fusarium wilt. We explored the role of constructing a healthy rhizosphere microflora seedlings. The method antibiotic resistance used to determine colonization ability HN6. effect on microbial communities assessed using culture-dependent high-throughput sequencing. infection process pathogen evaluated pot experiment confocal laser scanning microscopy. results showed that could prevent infection; it increased nutrient content diversity bacterial community rhizosphere, promoted plant growth, decreased mycotoxin fusaric acid abundance pathogens rhizosphere. Thus, relative species, fungi, bacteria induced change reorganization dominated by seedlings, evolved into not conducive occurrence diseases, shaping promoting growth banana.
