Abstract

China is the second-largest maize producer and consumer globally. During maize production, Fusarium spp. often gets infected, and mycotoxins like fumonisin contaminate it. Fumonisin has become the most widely polluted mycotoxin type in China. Planting genetically - modified maize is an economical and effective approach to reducing fumonisin pollution in products. This study aimed to evaluate the effectiveness of two transgenic events from China, Bt-Cry1Ab-Ma CM8101 and Bt-Cry1Ab, Cry2Ab, G10evo Ruifeng 8, in reducing fumonisin pollution in maize under the stress of natural and Lepidopteran pests (Ostrinia furnacalis, Mythimna separate, Helicoverpa armigera) in two Chinese sites from 2018-2019. The results showed that under the stress of Lepidoptera insects (O. furnacalis and H. armigera), the total amount of fumonisin in Bt maize decreased significantly. Maize with two insect-resistant transgenic events reduced fumonisin by over 70%. In years with serious fumonisin pollution, the effects of CM8101 and Ruifeng 8 on reducing pollution were more significant. Bt maize can provide area-wide pest management and thus contribute to a progressive phase-down of chemical pesticide use. Genetically-modified insecticidal crops can ensure food and nutrition security, contribute to the sustainable intensification of China's agriculture, and reduce the environmental footprint of food systems.

两个转基因抗虫玉米事件减少了中国鳞翅目昆虫胁迫下伏马菌素的污染。

中国是全球第二大玉米生产国和消费国。在玉米生产过程中，镰刀菌经常被感染，而像伏马菌素这样的真菌毒素会污染它。伏马菌素已成为中国污染最广泛的霉菌毒素类型。种植转基因玉米是减少产品中伏马菌素污染的一种经济有效的方法。本研究旨在评价2018-2019年中国2个转基因事件Bt-Cry1Ab- ma CM8101和Bt-Cry1Ab， Cry2Ab， G10evo瑞丰8号在自然和鳞翅目害虫（Ostrinia furnacalis, Mythimna separate, Helicoverpa armigera）胁迫下减少玉米伏马菌素污染的效果。结果表明，在鳞翅目昆虫（furnacalis和H. armigera）胁迫下，Bt玉米伏马菌素总量显著下降。具有两个抗虫转基因事件的玉米减少伏马菌素70%以上。在伏马菌素污染较为严重的年份，CM8101和瑞丰8号的减污效果更为显著。Bt玉米可以提供全区域虫害管理，从而有助于逐步减少化学农药的使用。转基因杀虫作物可以确保粮食和营养安全，有助于中国农业的可持续集约化，并减少粮食系统的环境足迹。

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 • Biofuels • Data from field trials • Development of transformation technology • Elimination of pollutants (Bioremediation) • Gene silencing mechanisms • Genome Editing • Herbicide resistance • Molecular farming • Pest resistance • Plant reproduction (e.g., male sterility, hybrid breeding, apomixis) • Plants with altered composition • Tolerance to abiotic stress • Transgenesis in agriculture • Biofortification and nutrients improvement • Genomic, proteomic and bioinformatics methods used for developing GM cops ECONOMIC, POLITICAL AND SOCIAL ISSUES • Commercialization • Consumer attitudes • International bodies • National and local government policies • Public perception, intellectual property, education, (bio)ethical issues • Regulation, environmental impact and containment • Socio-economic impact • Food safety and security • Risk assessments
