Immunomodulation confers herbicide resistance in plants

Immunomodulation confers herbicide resistance in plants.

In order to create a novel mechanism for herbicide resistance in plants, we expressed a single-chain antibody fragment (scFv) in tobacco with specific affinity to the auxinic herbicide picloram. Transgenic tobacco plants and seedlings expressing this scFv against picloram were protected from its effect in a dose-dependent manner. This is the first successful use of an antibody to confer in vivo...

Expression of bar in the plastid genome confers herbicide resistance.

Phosphinothricin (PPT) is the active component of a family of environmentally safe, nonselective herbicides. Resistance to PPT in transgenic crops has been reported by nuclear expression of a bar transgene encoding phosphinothricin acetyltransferase, a detoxifying enzyme. We report here expression of a bacterial bar gene (b-bar1) in tobacco (Nicotiana tabacum cv Petit Havana) plastids that conf...

Herbicide Phytotoxicity and Resistance to Herbicides in Legume Plants

Herbicide resistance and biodiversity: agronomic and environmental aspects of genetically modified herbicide-resistant plants

Farmland biodiversity is an important characteristic when assessing sustainability of agricultural practices and is of major international concern. Scientific data indicate that agricultural intensification and pesticide use are among the main drivers of biodiversity loss. The analysed data and experiences do not support statements that herbicide-resistant crops provide consistently better yiel...

Glyphosate and herbicide resistant plants

There is a common understanding that commercially traded formulations of glyphosate, such as Roundup, can be more toxic than glyphosate alone. Therefore, the EU has already taken measures to remove problematic additives known as POE tallowamine from the market. However, imports of genetically engineered plants resistant to glyphosate are exposed to high dosages of the herbicide in countries whe...
