摘要
为探讨极端生境-盐碱地下两种典型寄生药用植物肉苁蓉与锁阳的土壤微生物群落特点,本文基于微生物组-生态因子策略,对新疆艾比湖的肉苁蓉与锁阳土壤进行16S扩增子测序,分析土壤微生物群落的组成,并结合核心微生物组丰度及生态气候因子进行冗余分析和相关性分析。结果表明肉苁蓉土壤微生物群落多样性显著高于锁阳,肉苁蓉与锁阳核心微生物组为海单胞菌属Marinomona、盐单胞菌科Halomonadaceae、根瘤菌目Rhizobiales、嗜盐单胞菌属Halomonas及Acidimicrobiales。可区别二者土壤微生物群落的6个特异性生物标记物为微球菌科Micrococcacea、Echinicola及Glutamicibacter、Galbibacter,假交替单胞菌属Pseudoalteromonas、Marinobacterium_rhizophilum。冗余分析和相关性分析结果表明最干季度平均温度与最冷季度平均温度、粘土含量及土壤质地分类是影响肉苁蓉与锁阳土壤微生物群落组成的主要生态因子。本文为后期寻找肉苁蓉与锁阳的微生物分子标记,促进品质提高提供理论依据。
To explore the characteristics of soil microbial communities of Cistanche deserticola and Cynomorium songaricum,two typical parasitic medicinal plants that live in an extreme saline alkali environment,16S PCR was used to sequence the soil microbial communities of C.deserticola and C.songaricum in Ebinur Lake,Xinjiang.Redundancy analysis and correlation analysis were carried out based on the abundance of core microbiome and ecoclimatic factors.The results show that the diversity of the soil microbial community of C.deserticola was significantly higher than that of C.songaricum.The core microbial groups of C.deserticola and C.songaricum were Marinomona,Halomonadaceae,Rhizobiales,Halomonas,and Acidimicrobiales.Six specific biomarkers were identified as Micrococcacea,Echinicola,Glutamicibacter,Galbibacter,Pseudoalteromonas,and Marinobacterium_rhizophilum.The results of redundancy analysis and correlation analysis show that the average temperature in the driest season and the average temperature in the coldest season,and the clay content and soil texture classification were the main ecological factors affecting the composition of these soil microbial communities.This study provides a theoretical basis for finding molecular markers of C.deserticola and C.songaricum and promoting the quality of C.deserticola and C.songaricum.
