In order to study the effect of plant community composition on soil microbial communities in a typical Inner Mongolian grassland, the abundance and community structure of bacteria and fungi in bulk soils under different plant functional groups and in soils from the rhizosphere of different grass species were analyzed using real-time PCR and automated ribosomal intergenic spacer analysis (ARISA) under plant functional group removal treatments. Our results indicated that changes in plant functional group affect bacterial abundance, but not fungal abundance or bacterial/fungal community structure in bulk soil. The abundance of bacteria and fungi in the rhizosphere soil varied with plant species. Cluster analysis revealed that community structure of bacteria and fungi also varied among plant species in the rhizosphere soil but not in the bulk soil. which was more evident for bacteria. Our results point to the ways in which plant species can influence soil microbial and fungal communities through the action of their roots.
