ECM and ECM.S, ectomycorrhizae (Pinus armandii mycorrhized with Tuber indicum) and ectomycorrhizosphere soil. CK and CK.S, roots and soils from cultivated P. armandii without T. indicum partner. Each value is the mean of 3 replicates (±SD). Values followed by different lowercase letters indicate significant differences (P < 0.05) between samples in a line.
