Original Article


Here, we investigated the influence of Chinese white truffle (Tuber panzhihuanense) symbioses on the microbial communities associated with Corylus avellana during the early development stage of symbiosis. The microbial communities associated with ectomycorrhizae, and associated with roots without T. panzhihuanense colonization, were determined via high-throughput sequencing of bacterial 16S rRNA genes and fungal ITS genes. Microbial community diversity was higher in the communities associated with the ectomycorrhizae than in the control treatment. Further, bacterial and fungal community structures were different in samples containing T. panzhihuanense in association with C. avellana compared to the control samples. In particular, the bacterial genera Rhizobium, Pedomicrobium, and Herbiconiux were more abundant in the ectomycorrhizae, in addition to the fungal genus Monographella. Moreover, there were clear differences in some physicochemical properties among the rhizosphere soils of the two treatments. Statistical analyses indicated that soil properties including exchangeable magnesium and exchangeable calcium prominently influenced microbial community structure. Lastly, inference of bacterial metabolic functions indicated that sugar and protein metabolism functions were significantly more enriched in the communities associated with the ectomycorrhizae from C. avellana mycorrhized with T. panzhihuanense compared to communities from roots of cultivated C. avellana without T. panzhihuanense. Taken together, these results highlight the interactions among ectomycorrhizal fungi, soil properties, and microbial communities that are associated with host plants and further our understanding of the ecology and cultivation of the economically important T. panzhihuanense truffles.
