Heat map analyses of AM fungal communities in the root and soil samples. The relative abundances of the top 50 most abundant classified AM fungal OTUs were identified in each sample by colors deduced from the raw Z-scores. Hierarchical clustering of all samples was performed using average clustering method with the Euclidean distances. Soil_P represents soil sample in pure plantation; Soil_M represents soil sample in mixed plantation; Root_P represents root sample in pure plantation; Root_M represents root sample in mixed plantation
