This study analyzed the impact of Hedgehog mushroom on the endophytic microbial community of Quercus aliena. The results showed significant differences in the structure and dominant species of the endophytic microbial community in the roots, stems, and leaves of Q. aliena with or without H. erinaceus.
Hedgehog mushroom is a Hericium erinaceus associated with fagaceae and pinaceae trees in the northern hemisphere. It is still unknown whether this symbiotic relationship will affect the endophytic microbial community of the host plants. In this study, the endophytic microbial communities of different Quercus aliena tissues (root, stem, and leaf) with or without H. erinaceus partner were analyzed by bar-coded pyrosequencing. About 29,000 clean reads were obtained per sample representing 28 phyla of bacteria and 6 phyla of fungi. A total of 26,838 operational taxonomic units (OTUs) of bacteria and 4323 OTUs of fungi were observed at a 97% similarity level. Three bacterial phyla, Proteobacteria, Cyanobacteria and Bacteroidetes, and fungal phylum Ascomycota were dominant in all tissues. The relative abundance of these dominant communities showed significantly differences between Q. aliena tissues with or without H. erinaceus. Bacterial genus Pseudomonas and fungal genus Cryptosporiopsis were species-rich in Q. aliena root infected by H. erinaceus hyphae. This study demonstrated that the endophytic microbial community structure and dominant species varied in Q. aliena mycorrhized with H. erinaceus.
