Analysis of soil bacterial community composition by 16S rDNA clone library sampling from transgenic carnation

Abstract:

[Objective] We did this research to analyze the impact on the soil bacterial population of the transgenic carnation, which laid the foundation for the safety assessment of GM carnation. [Methods] Bacterial 16S rDNA gene clone libraries of GM and non-GM carnations were constructed, and the soil bacterial populations of these carnations were compared. [Results] The results showed Alphaproteobacteria, Betaproteobacteria, Planctomycetes and Acidobacteria were shared with GM and non-GM carnation. Some differences were found in Actinobacteria, Verrucomicrobia and uncultured bacterium clone. [Conclusion] The results indicated that high bacterial diversity was found in these GM carnation soil bacterial libraries, and the cultivation of genetically modified carnation did not have a significant impact on the soil bacterial community structure.
