Genetically modified maize 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.

Genetically Modified Maize. Biotechnology has made it possible to transfer genetic material within a species as well as between species. As a result of this development, the first genetically modified (GM) maize seed to resist pests, known as Bt (Bacillus thuringiensis) maize, was released in 1997. Bt maize has saved farmers millions of dollars ...

MON 802 is an Insect Resistant maize under license from Monsanto Company. [2] Corn line MON802 was developed through genetic modification to be tolerant [ 3 ] to glyphosate herbicide and protect the plant from the European corn borer (Ostrinia nubilalis) (the Bt trait).

2018年2月15日 · A comparison of soil microbial community structure, protozoa and nematodes in field plots of conventional and genetically modified maize expressing the Bacillus thuringiensis CryIAb toxin.

2021年10月13日 · Maize transformation, which is a prerequisite for genetically modified maize development, is no longer a major bottleneck. Protocols using morphogenic regulators have evolved significantly towards increasing transformation frequency and genotype independence.

In October 2014 the US EPA registered Dow's Enlist Duo maize, which is genetically modified to be resistant to both glyphosate and 2,4-D, in six states. [150] [151] [152] Inserting a bacterial aryloxyalkanoate dioxygenase gene, aad1 makes the corn resistant to 2,4-D. [150] [153] The USDA had approved maize and soybeans with the mutation in ...

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.

2023年9月20日 · To interrogate the effects of zmm28 in the field, researchers introduced genetic changes that result in the overexpression of the gene into two elite inbred lines. (Intense selection over the...

2024年1月17日 · Genetically modified maize DP915635 was developed to confer tolerance to glufosinate herbicide and resistance to corn rootworm pests. These properties were achieved by introducing the ipd079Ea, mo-pat and pmi expression cassettes.

2024年11月11日 · Genetically modified maize DP51291 was developed to confer control against susceptible corn rootworm pests and tolerance to glufosinate-containing herbicide; these properties were achieved by introducing the ipd072Aa, pmi and mo-pat expression cassettes.
