Abstract
Rhizosphere bacterial community studies offer valuable insights into the environmental implications of genetically modified (GM) crops. This study compared the effects of a non-GM maize cultivar, namely Hi-IIA, with those of a herbicide-resistant maize cultivar containing the phosphinothricin N-acetyltransferase gene on the rhizosphere bacterial community across growth stages. 16s rRNA amplicon sequencing and data analysis tools revealed no significant differences in bacterial community composition or diversity between the cultivars. Principal component analysis revealed that differences in community structure were driven by plant growth stages rather than plant type. Polymerase chain reaction analysis was conducted to examine the potential horizontal transfer of the introduced gene from the GM maize to rhizosphere microorganisms; however, the introduced gene was not detected in the soil genomic DNA. Overall, the environmental impact of GM maize, particularly on soil microorganisms, is negligible, and the cultivation of GM maize does not alter significantly the rhizosphere bacterial community.
期刊介绍：
GM Crops & Food - Biotechnology in Agriculture and the Food Chain aims to publish high quality research papers, reviews, and commentaries on a wide range of topics involving genetically modified (GM) crops in agriculture and genetically modified food. The journal provides a platform for research papers addressing fundamental questions in the development, testing, and application of transgenic crops. The journal further covers topics relating to socio-economic issues, commercialization, trade and societal issues. GM Crops & Food aims to provide an international forum on all issues related to GM crops, especially toward meaningful communication between scientists and policy-makers.
GM Crops & Food will publish relevant and high-impact original research with a special focus on novelty-driven studies with the potential for application. The journal also publishes authoritative review articles on current research and policy initiatives, and commentary on broad perspectives regarding genetically modified crops. The journal serves a wide readership including scientists, breeders, and policy-makers, as well as a wider community of readers (educators, policy makers, scholars, science writers and students) interested in agriculture, medicine, biotechnology, investment, and technology transfer.
Topics covered include, but are not limited to:
• Production and analysis of transgenic crops
