China is currently the only country that has commercialized genetically engineered tree species, and this has attracted worldwide attention. As a perennial tree species, transgenic poplar has a long growth cycle and needs to be tested for long-term ecological risks. The main purpose of this study was to explore the ecological safety of perennial transgenic poplars in arthropod community, physical and chemical properties of soil, gene flow, and soil microbial diversity. The study found transgenic poplars could effectively inhibit the number of pests. Moreover, transgenic poplar 741 did not affect the stability of the arthropod community. Studies on the microbial diversity of poplar showed that transgenic poplars did not affect the physical and chemical properties of the soil and the soil microbial community structure. Furthermore, the microbial community structure was obviously affected by location and season. The results showed that a 5-year-old transgenic 741 poplar did not pose an ecological risk, and did not affect the microbial community structure or functional diversity. This study provides a reference for the ecological security evaluation of transgenic poplars, and provides a theoretical basis for promoting the commercialization of transgenic poplars.
A 5-year field study showed no apparent effect of the Bt transgenic 741 poplar on the arthropod community and soil bacterial diversity (held on an external server, and so may require additional authentication details)
