摘要:

根际微生物群落对植物健康与土壤生态功能至关重要。本研究旨在解析特色作物荞麦(Fagopyrum tataricum)的根际微生物组结构。以种植于云南昆明农田的荞麦为研究对象,采用全长16S rRNA基因高通量测序技术,比较分析其根际与非根际土壤的微生物群落。结果表明,所有样本在门、纲、属水平均表现出丰富的多样性,共鉴定出19门、36纲、257属。其中,拟杆菌门(Bacteroidota)、变形菌门(Proteobacteria)和疣微菌门(Verrucomicrobiota)为核心优势菌门。主成分分析显示,根际与非根际土壤样本沿主成分轴显著分离,证实了荞麦根系对其根际微生物群落结构具有显著的塑造作用。进一步分析鉴定出8个在根际中显著富集的操作分类单元(OTUs),其主要归属于铁杆菌属(Ferruginibacter)、黄腐杆菌属(Flavihumibacter)、黄噬菌属(Flavisolibacter)和土单胞菌属(Terrimonas)等。
