Application of phosphate-solubilizing microorganisms(PSMs)has been reported to increase P uptake and plant growth.However,no information is available regarding the ecological consequences of the inoculation with PSMs.The effect of inoculation with phosphate-solubilizing fungal(PSF)isolates Aspergillus niger P39 and Penicillium oxalicumreaction-denaturing gradient gel electrophoresis(PCR-DGGE).Compared with the control,the number of culturable microbes for soybean Was significantly greater with P39,whereas for maize,the same Was significantly greater with P66.In addition,a greater number of microbes were fouud in the rhizosphere of maize compared with soybean.The fingerprint of DGGE for 16S rDNA indicated that inoculation with PSF also increased bacterial communities,with the P66 treatment having higher numbers of DGGE bands and a higher Shannon-Weaver diversity index compared with P39;the composition of the microbial community was also more complex with the P66 treatment.Overall,complex interactions between plant species and exotic PSMs affected the structure of the bacterial community in the rhizosphere.but plant species were more important in determining the bacterial community structure than the introduction of exotic microorganisms.
