Plants in the wild could be given resistance to herbicides.

Genetic modification of crops to make them resistant to herbicides has been widely employed to create advantages for the varieties of rice that are weedy. This suggests that this genetic modification may also have potential to impact wild animals.

ラウンドアップ Many crops have been genetically engineered to resist the glyphosate. This herbicide, initially known as Roundup, was introduced into the market in 1996 under the trade name Roundup. This resistance allows farmers to eliminate most the weeds that grow in their fields without causing harm to their crops.

Glyphosate is a plant-killer by blocking EPSP synase which is an enzyme that plays a role in the production amino acids, as well as other chemical compounds which comprise around 35% of the plant’s mass. Genetic modification, which is used by Monsanto’s Roundup Ready crops, which are based in St Louis (Missouri), typically involves inserting genes into the DNA of a plant to boost EPSP synthase production. Genes usually come from bacteria that infect plants.

The addition of EPSP synase allows for plants to resist the harmful effects of glyphosate. Biotechnology labs tried to use plant genes to boost EPSP synthase production.ラウンドアップマックスロード/ This was partially to exploit a loophole within US law that permits regulatory approval for transgenes in organisms that have not been derived from bacteria pests.

A few studies have explored whether transgenes like those which confer glyphosate resistance can help plants compete in reproductive success and longevity once they’re introduced to weedy or wild relatives by cross-pollination. Norman Ellstrand of the University of California, Riverside, said that the traditional expectation was that any transgene will confer disadvantage in nature if there is no selection pressure. This is because any extra machines would reduce the effectiveness of.

Lu Baorong is an ecologist at Fudan University Shanghai. His research shows that resistance to glyphosate offers a significant health benefit, even if it isn’t applied.

Lu and his coworkers genetically modified the rice species to express the EPSP synthase, and then crossed it with the plant that was weedy.

The group then let the offspring of crossbreeding to cross-breed with one other to create second-generation hybrids. They were identical genetically with the exception of the amount of EPSP synthase genes they carried. The team found that those who had greater copies of the gene that encodes EPSP synthase expressed more enzymes and produced more tryptophan which is what we expected.

The researchers also found that the hybrids with transgenic genes had higher rates of photosynthesis. ラウンドアップ ハイロード They also produced more flowers and shoots and produced 48-125percent more seeds per plant than non-transgenic hybrids- in the absence of glyphosate.

Lu says that making the weedy grain more competitive can cause more problems for farmers across the world who have crops infected by the pest.

ラウンドアップ Brian Ford Lloyd, a UK plant scientist, stated that the EPSP Synthase gene could get in wild rice varieties. This could threaten the genetic diversity of their species, which is very important. ラウンドアップ 希釈 “This is one clear example of the extremely plausible detrimental effects [of GM plantson our environment.”

There is a popular belief that genetically engineered plants with extra copies or microorganisms genes are less risky than those containing only their own genes. Lu states, “Our study shows this is not the case.”

Researchers say this discovery requires rethinking the future regulation on the use of genetically modified plants. ラウンドアップ “Some people are now suggesting that biosafety regulations can be relaxed because we have an incredibly high level of confidence in the last two years of genetic engineering” Ellstrand says. “But the research shows that novel products still need cautious examination.”
