Distinct Ectomycorrhizospheres Share Similar Bacterial Communities as Revealed by Pyrosequencing-Based Analysis of 16S rRNA Genes

Analysis of the 16S rRNA gene sequences generated from Xerocomus pruinatus and Scleroderma citrinum ectomycorrhizospheres revealed that similar bacterial communities inhabited the two ectomycorrhizospheres in terms of phyla and genera, with an enrichment of the Burkholderia genus. Compared to the bulk soil habitat, ectomycorrhizospheres hosted significantly more Alpha-, Beta-, and Gammaproteobacteria.
