Genetically modified maize (corn) is a genetically modified crop. Specific maize strains have been genetically engineered to express agriculturally-desirable traits, including resistance to pests and to herbicides. Maize strains with both traits are now in use in multiple countries.

In 1996, GM maize (corn) and GM soybeans were approved and planted in the US, and thereafter processed foods containing GMOs started to appear in retail stores in the US and Canada. The genetically derived advantage of most GM crops, such as soybean, corn, rapeseed, and cotton, is the ability to be resistant to specific herbicides or certain ...

2018年2月15日 · Results provided strong evidence that GE maize performed better than its near isogenic line: grain yield was 5.6 to 24.5% higher with lower concentrations of mycotoxins (−28.8%), fumonisin...

GM maize. Two lines of Chardon LL herbicide-resistant GM maize expressing the gene of phosphinothricin acetyltransferase before and after ensiling showed significant differences in fat and carbohydrate contents compared with non-GM …

2018年12月1日 · GM Bt maize reduces yield loss to Lepidopteran and Coleopteran insect pests. Delaying adoption of GM crops presents risks to humans and environment. The anticipated world population growth emphasizes a need to produce more food on less land.

2021年2月18日 · GM maize increased mean yields over CH by 0.42 metric tons (Mt) ha −1 and reduced yield risk. We show that GM white maize increased yields by 0.60 Mt ha −1 and GM yellow maize by 0.27 Mt...

2002年11月1日 · This debate, which addresses both safety and ethical aspects, has raised questions about the impact of genetically modified (GM) crops on the biodiversity of traditional landraces and on the environment. Here, we review some of the key points of maize genetic history as well as the methods used to stably transform this cereal.

2021年10月13日 · Over the last three decades, genetically modified (GM) maize varieties have successfully reached the market, which has brought traits such as herbicide resistance and insect resistance to farms. The first generation of varieties incorporated a single gene with only one mode of action against one insect order for insect resistance.

High-dose/refuge strategy: Tactic used to delay insect resistance to a genetically modified (GM) crop that involves planting non-GM plants (refuge) to produce susceptible insects. In order...

2025年2月14日 · In this study, we assess the safety of GM maize, which has high potential for future commercialization and high current risk of release into natural ecosystems. In particular, since research on the impact of GM crops on soil is necessary, we investigated whether GM maize causes changes in soil microbial communities.
