Effect of Transgenic Populus deltoides ×P. euramericanna cv. ‘Nanlin 895’ with PeTLP on Soil Microbes and Molecular Analysis on Exogenous Genes

Transgenic Populus deltoides× P. euramericana cv. ‘Nanlin 895’ with PeTLP gene were selected for molecular analysis and biosafety analysis. The results showed that the exogenous gene could be detected after one year plantation of transgenic poplars in the open field. There was no significant difference in the quantity of soil microbes around root system between transgenic and non-transgenic plants, indicating that the transgenic plants with PeTLP had no significant effects on soil microbes. Molecular analysis on total DNA of soil microbes showed that the exogenous gene did not transfer to the soil microbes. Allelopathy effect of leaf of transgenic ‘Nanlin 895’ showed that it had no significant effect on the seed growth of Lactuca sativa L. var. ramose Hort.
