| Abstract: |
| To explore the variation of microbial community after root rot infection of Bupleurum chinense DC, high\|throughput sequencing was employed to systematically analyze the fungal and bacterial community structures, temporal variations, and functional profiles of key differential taxa in bulk soil, rhizosphere soil, and root of B. chinense at healthy, early\|stage, and late\|stage of disease. The results showed that root rot predominantly affected the microbial communities inside the root. As the disease progressed, the diversity of root\|associated fungal communities significantly declined, with Chao1 and ACE indices decreasing by 65.69% and 65.75%, respectively. The relative abundance of the genus Fusarium increased markedly from 0.47% in healthy samples to 9.63% in the late\|stage infected samples. F.solani had the highest LDA score among the late\|stage differential groups, suggesting that it may be the primary pathogenic bacterium of root rot in B. chinense. In contrast, bacterial diversity in roots increased with disease progression, with Chao1 and ACE indices rising by 90.18% and 86.52%, respectively. Notably, the Allorhizobium\|Neorhizobium\|Pararhizobium\|Rhizobium complex was identified as a specific and significantly enriched taxon in the late\|stage differential group, showing a 106.22% increase in relative abundance. It is speculated that B. chinense may enhance its disease resistance by recruiting beneficial bacteria. |
