To study the potential influence of transgenic Populus simonii×P. nigra on the soil microbial community composition and horizontal exogenous gene transfer, fresh transgenic leaves were treated in broadleaf and coniferous forest soil for 6 months in the laboratory. The results showed that DNA fragments of the target and marker genes were completely degraded before 120 days. The dominant colony is the bacterium whose number is much more than that of other microbes under the same treatment. The number of cultivable bacteria treated by transgenic litters was significantly higher than the number treated by non-transgenic litters in selective medium with kanamycin. The target gene in the entophytic and soil bacteria, with 1.92% and 3.08% PCR-positive results, was found only in broadleaf forest soil. This result showed a certain possibility of horizontal gene transfer from the transgenic poplar to soil bacteria.
