摘要:

为研究杭白芍道地产区不同定植时间下土壤细菌、真菌、古菌的组成和结构变化,并筛选道地产区杭白芍根际的友好菌种,对浙江省东阳市1、2、3、4 a生的杭白芍根际土壤样品进行微生物菌群结构分析,解析杭白芍定植过程中根际土壤的微生物组成特征及演替规律,同时利用EggNOG、KEGG和CAZy数据库进行菌群功能预测。结果表明:杭白芍根际土壤微生物组成主要为细菌(85.561%~91.680%)、古菌(0.481%~2.804%)、真菌(0.018%~0.030%)、病毒(0.022%~0.117%),其他微生物占比为7.516%~11.500%。随着定植时间的增加,部分劣势菌群逐渐丧失,菌群多样性降低,细菌相对丰度升高,1 a生杭白芍根际土壤细菌相对丰度为85.561%,4 a生时达到91.680%;古菌与病毒的相对丰度下降,1 a生时分别为2.804%和0.117%,4 a生时分别降至0.481%和0.022%;真菌的相对丰度先升后降,1 a生时为0.018%,3 a生时达到峰值(0.030%),4 a生时下降至0.024%。此外,Candidatus Rokubacteria和硝化螺旋菌属(Nitrospira)为道地产区多年生杭白芍根际的标志物种。上述结果表明,在杭白芍道地产区,随着定植时间的累积,菌群多样性降低,并招募和富集了Candidatus Rokubacteria、硝化螺旋菌属等特征菌种。

Abstract:

To investigate the changes in the composition and structure of soil bacteria,fungi,and archaea under different planting durations in the genuine producing area of Hangbaishao,and to screen for beneficial microbial strains in the rhizosphere of Hangbaishao in this area,rhizosphere soil samples of Hangbaishao aged 1,2,3,and 4 years were collected from Dongyang City,Zhejiang Province. Microbial community structure analysis was conducted to elucidate the microbial composition characteristics and succession patterns in the rhizosphere soil during Hangbaishao colonization. Functional predictions of the microbial communities were performed using the EggNOG,KEGG,and CAZy databases. The results showed that the microbial composition of Hangbaishao soil was dominated by bacteria(85.561%-91.680%),archaea(0.481%-2.804%),fungi(0.018%-0.030%),and viruses(0.022%-0.117%),with other microorganisms accounting for 7.516%-11.500%. As planting duration increased,some inferior microbial groups gradually disappeared,and microbial diversity decreased. The relative abundance of bacteria increased from 85.561% in the 1-year-old rhizosphere soil to 91.680% in the 4-year-old soil. The relative abundances of archaea and viruses declined from 2.804% and 0.117%(1-year-old)to 0.481% and 0.022%(4-year-old),respectively. The relative abundance of fungi first increased and then decreased,from 0.018%(1-year-old)to a peak of 0.030%(3-year-old),and then dropped to 0.024%(4-year-old). Furthermore,CandidatusRokubacteria and Nitrospira were identified as signature taxa in the rhizosphere soil in the genuine producing area. These results indicate that with increasing planting duration in the genuine producing area of Hangbaishao,microbial diversity decreases,while characteristic taxa such as CandidatusRokubacteria and Nitrospira are recruited and enriched.
