Benefits of genetically modified plants over weeds

Plants in the wild could be given herbicide resistance.

It has been proven that a technique for genetic modification, which is widely used to make crops herbicide-resistant, gives advantages to a weedy variety of rice. This suggests that the genetic modification could also have potential to have an impact on wild animals.

There are many kinds of crops are genetically modified to be resistive to the glyphosate. Roundup was the first herbicide to be sold. https://search.rakuten.co.jp/search/mall/ラウンドアップ+マックスロード/ -resistant crop allows farmers to eradicate the majority of plants without harming their crops.

Glyphosate blocks an enzyme called EPSP synthase, which is responsible for the creation of specific amino acids and other molecules. It can also inhibit the growth of plants. ラウンドアップ of genetic modification, which is employed in Roundup Ready crops by Monsanto (based in St Louis in Missouri) is the process of inserting genes in a plant to boost EPSP synthase production. Genes are typically obtained from bacteria that cause disease to crops.

The plant is able to resist the adverse effects of glyphosate due to the addition of EPSP synthase. ラウンドアップ amazon tried to utilize the genes of plants to boost EPSP-synthase levels, in part to exploit an American loophole that permits regulatory approval of transgenes that are not derived from by bacterial pests.

Few studies have explored whether transgenes that confer glyphosate tolerance could -- after they are weedy or become wild relatives through cross-pollinatingenhance the plant's survival and reproduce. Norman Ellstrand of University of California Riverside says, "The conventional expectation is that any type of transgene in the wild will confer disadvantage if there's no selection pressure , because the added machinery can reduce the fitness."

Lu Baorong of Fudan University in Shanghai is now challenging that view. https://www.yodobashi.com/product/100000001002109951/ shows that resistance to glyphosate even when not applied to a weedy variety of the rice crop can provide a significant health boost.

The team allowed the offspring from cross-breeding to breed with one another, resulting in second-generation hybrids that are genetically identical to each other except for the amount of copies the gene encodes EPSP synase. ラウンドアップ found that the hybrids with greater than one copy of the gene that encodes EPSP synthase expressed more enzyme and also produced more tryptophan, as expected.

Researchers also found that transgenic hybrids grew between 48-125% more seeds per plant. They also had more photosynthesis, and had more shoots than the non-transgenic varieties.

Lu states that making weedy crops more competitive can increase the difficulties it causes to farmers around the world whose crops are affected by the insect.

Brian Ford-Lloyd of the University of Birmingham, UK Brian Ford-Lloyd from the University of Birmingham, UK "If the EPSP synthase gene is introduced to wild rice species, their genetic variety is crucial in conserving it, could be at risk because it could outcompete the normal varieties." This is among the most clear examples of plausible negative effects [of GM crop on the environment."

ラウンドアップ challenges the perception that genetically modified crops containing more copies of their genes are safer than crops that have microorganism genes. Lu claims that the study doesn't support this notion.

The research results call for a review of future regulations for genetically modified crops, some scientists say. Ellstrand states "Some people believe that the biosafety regulations should be looser." Ellstrand adds: The study revealed that the newest products should be evaluated carefully.
