Rhizosphere microbiome promotes plant growth; however, the succession of rhizosphere microbial community during the growth stages of perennial medicinal plant () is still unclear. Here, amplicon sequencing was performed to assess the succession characteristics of rhizosphere microbiomes during developmental stages. Results showed that bacterial and fungal communities were mainly shaped by the development stages. The microbial α-diversities first increased and then decreased with plant growth and the variation in microbial composition was active at the 3-year root growth (3YR) stage. The variation trend of cross-domain co-occurrence network complexity was similar to that of α-diversities. Cross-domain nodes decreased at the 3YR stage and fungal nodes increased at the 3YR stage. This study provided a detailed and systematic survey of rhizosphere microbiomes during the growth stages of . The findings revealed that the development stages of drove the temporal dynamics of rhizosphere communities. This study helps in harnessing the power of microbiomes to evaluate herbal medicine growth and provides valuable information to guide the microbial breeding of medical plants.
根际微生物群促进植物生长;然而,多年生药用植物()生长阶段根际微生物群落的演替仍不清楚。在此,进行扩增子测序以评估发育阶段根际微生物群的演替特征。结果表明细菌和真菌群落主要受发育阶段影响。微生物α多样性随植物生长先增加后降低,且微生物组成的变化在3年生根生长(3YR)阶段较为活跃。跨域共现网络复杂性的变化趋势与α多样性相似。跨域节点在3YR阶段减少,真菌节点在3YR阶段增加。本研究对()生长阶段根际微生物群进行了详细而系统的调查。研究结果表明()的发育阶段驱动了根际群落的时间动态。本研究有助于利用微生物群的力量评估草药生长,并为指导药用植物的微生物育种提供有价值的信息。
