Frequently observed fungal OTUs are listed in terms of the number of observations in 159 root samples. Number of links to plants, the result of CLAM test (Fig. 3), and d' measure of specificity to host plants are shown. Detailed identification of the ascomycete OTUs was performed based on a phylogenetic analysis (Fig. S1). The results of normal BLAST search are also shown with E-values and maximum identity scores.
Significantly high specificity to host plants (P < 0.05).
Taxonomic information was assigned at species level (Lactarius quietus).
Fungus detected only from root samples; habitat specificity was not assigned by CLAM test due to a small number of observations (Fig. 3).
