Abstract
Several genetically modified (GM) potatoes have been developed by introducing endogenous genes derived from potatoes, such as asparagine synthetase-1 (Asn1) and polyphenol oxidase 5 (Ppo5), to improve quality. Therefore, it is difficult to distinguish between GM and non-GM potatoes. In this study, we developed a sequence-specific polymerase chain reaction (PCR) detection method to identify innate and inserted genes. We designed four Asn1 gene-specific primers and eight construct-specific detection primers to evaluate GM potatoes (E12, X17, and Y9) and non-GM crops. Consequently, PCR products corresponding to the original endogenous potato genes and the inserted genes were clearly distinguished and simultaneously identified. In addition, the PCR method demonstrated sufficient sensitivity to identify GM content at levels as low as 0.5%. Thus, this study offers an effective detection method for monitoring or screening approved and unapproved GM potato events using Asn1 and Ppo5 transgenes in foods and feeds.
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
• Gene insertion studies
• Gene silencing
• Factors affecting gene expression
• Post-translational analysis
• Molecular farming
• Field trial analysis
• Commercialization of modified crops
• Safety and regulatory affairs
BIOLOGICAL SCIENCE AND TECHNOLOGY
