Fig. 1.

Alpha-diversity comparison among the fruit bodies, rhizomorphs of Cantharellus cibarius, and mycosphere samples based on a) the Shannon and b) Ace indexes using the 16S rRNA gene amplicons sequencing data. Samples with the same letter do not differ significantly by Tukey’s test at p > 0.05; samples with different letters are significantly different by Tukey’s test at p < 0.05. The center value of each sample represents the median for the different indexes.

Fig. 3.

Statistical comparison of the relative abundance of microbiota among the three sampled parts of Cantharellus cibarius.Comparison of a) dominant phyla and b) dominant genera in the fruit bodies, rhizomorphs, and mycosphere samples. The y-axis represents names of taxa at the dominant phyla or genera level; the x-axis represents average relative abundance; colored columns represent different sampled parts of C. cibarius. Values on the far right are the p values, *0.01 < p ≤ 0.05, **0.001 < p ≤ 0.01, ***p ≤ 0.001.

Principal coordinate analysis (PCoA) of microbial communities in three sampled parts of Cantharellus cibarius. Circles, triangles, and diamonds represent the fruit bodies, rhizomorphs, and mycosphere, respectively. Distances between symbols on the ordination plot reflect relative dissimilarities in community structures.

(a) Heatmaps representing the differences in core bacterial group members and potential functions between a) fruit bodies and b) rhizomorphs of Cantharellus cibarius. The abscissa represents the members of the core bacterial group in each sampled part of C. cibarius, and the ordinate represents the potential functional types.
