Usage

General Description

Glufosinate-N-Acetyl is a chemical compound primarily used as a herbicide. It acts as a broad-spectrum contact herbicide and is utilized to control a wide range of weeds after the crop emerges or for total vegetation control on land not used for cultivation. It inhibits the enzyme responsible for nitrogen metabolism in plants, causing the plant to die. Glufosinate-N-Acetyl is also an integral compound in genetically modified crops designed to be resistant to the herbicide, allowing for more efficient weed control without damaging the crop. Due to its toxic nature, there is some controversy over its use and impact on the environment.

Liquid chromatography-diode array detection to study the metabolism of glufosinate in Triticum aestivum T-590 and influence of the genetic modification on its resistance

The resistance to glufosinate of two lines - genetically modified (GM) and unmodified (T-590 and T-549, respectively) - of Triticum aestivum has been studied. In the GM line, the bar gene was introduced to increase the resistance to glufosinate. Experiments in a controlled growth chamber showed that line T-590 presented a high resistance to glufosinate with an ED50 value of 478.59 g active ingredient per hectare (g ai ha-1) versus 32.65 g ai ha-1 for line T-549. The activity of glutamine synthetase (GS) in leaf extracts from both lines was investigated. The I50 for line T-590 was 694.10 μM glufosinate versus 55.46 μM for line T-549, with a resistance factor of 12.51. Metabolism studies showed a higher and faster penetration of glufosinate in line T-549 than in line T-590. LC-TOF/MS analysis of glufosinate metabolism at 48 h after herbicide treatment (300 g ai ha -1) revealed an 83.4% conversion of the herbicide (66.5% in N-acetyl-glufosinate metabolite), while in line T-549 conversion of the herbicide was about 40% (0% to N-acetyl-glufosinate). These results suggest that metabolism of glufosinate by the bar gene is a key mechanism of resistance in line T-590 that explains such high levels of herbicide tolerated by the plant, together with other mechanisms due to unmodified pathway, absorption and loss of glufosinate affinity for its target site.
