According to foreign media reports, a new study shows that the mutant plants can be used to clean up explosives contaminated theater and military training venues. Trinitrotoluene (TNT) contained in explosives has serious toxic effects on plants and has a significant effect on the establishment of soil and vegetation.
Trinitrotoluene precipitate block plant roots, inhibit plant growth and development. Trinitrotoluene plays an important role in the defense of a country, although some toxic and polluting chemicals are banned. Biologists at the University of York in the UK are now taking a significant step forward by making it possible to clean millions of hectares of land contaminated with explosives.
The team at the New York Agricultural Products Center, Department of Biology, York, described the mechanism of TNT toxicity in plants and raised the possibility of developing a new method called "explosive remediation techniques." This study also made possible the emergence of a new herbicide.
Researchers found a key plant enzyme, MDHAR6. It reacts with trinitrotoluene to produce reactive peroxides that cause great damage to the cells. But the mutant plants do not have this enzyme, thereby enhancing the tolerance of trinitrotoluene. Targeting this enzyme in the relevant plant species will allow scientists to develop plants that are resistant to trinitrotoluene. In contaminated areas such as military bases and junk manufacturing sites, the new plant not only regrouped but also cleared explosives.
Neil Bruce, of York University, said: "We are very much interested in the natural mechanisms of removing toxic chemicals from the biosphere, which have been heavily polluting, especially at military training bases, causing serious pollution of land and water sources, so the remedy Work is an urgent global issue. "
Leeds-Reutert said: "From this goal, our work is a very important step toward the successful use of plant-based systems for the clean-up of contaminated sites by removing the acute toxicity of TNT "
MDHAR6 is a plant-specific ingredient, so chemicals like Trinitrotoluene that react with this enzyme can easily degrade in the environment.
Bruce said: "This is an important discovery because the growing resistance of herbicides has been a topic of great concern since the 1970s and no new commercial herbicide has been commercially available since the 1980s."
