From 1996 to 2013, the planting area of genetically modified (GM) crops around the world increased by more than 100 times, therefore the genetic engineering is considered to be the most rapidly used crop technology in the history of modern agriculture. The planting area of GM crops of China is the sixth on the world. Based on the research and development situation, application situation, the import situation and the safety management, the development of GM crops in China were summarized. This article focused on the progress of Genetically Modified Organisms Breeding Major Projects in our country, approval of GM crops, planting situation of transgenic cotton and papaya, the type and amount of imported GM crops nearly five years, as well as our country's laws and regulations, management institution of GM organisms and approval process. Finally, we put forward the idea of GM crops industrialization development. We hope the reader to have an overall and macroscopical understanding on the development of GM crops industry in China.

Maize is not only a staple food crop but also an important raw material for feed and industry; however, the threat of weeds leads to a serious decline in its output and quality. The G2-aroA gene confers glyphosate herbicide tolerance to crops. In this study, the food safety of genetically modified (GM), glyphosate-tolerant maize with the G2-aroA gene was evaluated in a 90-day feeding study in Sprague-Dawley (SD) rats. Maize grain from GM or non-GM isogenic control lines were separately formulated into rodent diets at concentrations of 12.5% (low level), 25% (middle level), and 50% (high level). An additional group of rats were fed a commercialized diet as a control. The toxicological response variables, including body weights, food consumption, serum biochemistry, hematology, and absolute and relative organ weights, were compared between rats fed GM maize and those fed non-GM maize after consumption of test diets for 90. days. In addition, gross and microscopic pathology were conducted among treatment groups. No adverse effects related to the consumption of GM maize were detected in the subchronic feeding study. These results indicated that the GM glyphosate-tolerant maize was as safe and nutritious as conventional maize. © 2012 Elsevier Ltd. Source
