Engineering crop resistance to the naturally occurring glutamine synthetase inhibitor phophinothricin
1993
Chemical plant protection will be always needed, but the application of gene technology can reduce the impact of agriculture to the environment and offer new attractive systems for weed control to the farmer. The non-selective herbicide glufosinate exhibit desirable properties, which makes it suitable for weed control in crops. By transferring a microbial resistance gene from the producer of the active principle of glufosinate, sensitive crops like corn, oilseed-rape, soy bean and sugarbeet could be made resistant. In comparison to present, on soil herbicides based weed control systems, the flexibility in the application of the post-emergent foliar herbicide glufosinate in resistant crops comes closer to an ideal system. The introduction of this new system will be another important step towards an agriculture with reduced impact on the environment.
