Genetically modified plants are more beneficial than weeds

Wild plants could be able to resist herbicides.

It has been established that a genetic-modification technique, which is widely used to make crops resistant to herbicides, can provide advantages to an invasive variety of rice. This indicates that the modifications could affect the natural environment beyond farms.

Many cultivars are genetically altered so that they can resist the effects of glyphosate. The herbicide was initially offered under the trade name Roundup. ラウンドアップ -resistant crop allows farmers to eliminate the majority of herbicides in their fields without harming their crop.

Genetic modification, such as the Roundup Ready crops manufactured by Monsanto in St. Louis, Missouri, involves inserting genes to a crop's genetic code to boost EPSP production. Genes are typically derived usually from bacteria that infect plants.

The added EPSP synthase lets the plant be resistant to the effects of glyphosate. Biotechnology labs have also attempted to use plants' genes to increase the EPSP synthase enzyme, in part to exploit an American loophole that permits regulatory approval of transgenes which are not derived from bacterial pests.

ラウンドアップ have investigated whether transgenes such glyphosate-resistant genes could -- after introduction to wild or weedy plants through cross-pollination enhance the competition of plants in reproduction, survival and growth. ラウンドアップ of the University of California, Riverside, stated that the conventional expectation was that any transgene could cause disadvantage in nature when there is no selection pressure. This is because extra machinery would lower the effectiveness of.

Lu Baorong, an ecologist from Fudan University in Shanghai has changed the way that he views this. ラウンドアップ has discovered that resistance to glyphosate provides an impressive fitness boost to the weedy version of the common rice crop Oryza Sativa.

Lu and his associates modified cultivated rice varieties to produce more EPSP synthase. They also crossed the modified rice with a weedy related. ラウンドアップ was published in NewPhytologist 1.

The team allowed the offspring from cross-breeding to breed with one another, resulting in second-generation hybrids that are genetically identical with each other except for the number of copies of the gene that encodes EPSP synase. As expected, https://auctions.yahoo.co.jp/search/search?rkf=2&p=%E3%83%A9%E3%82%A6%E3%83%B3%E3%83%89%E3%82%A2%E3%83%83%E3%83%97&aucmaxprice=999999999&thumb=1&s1=score2&o1=a&isdd=1&ei=utf-8&fixed=3&nockie=1&isnext=1&ex_cat=2084006160,2084008038,2084034075&rewrite_ok_wand_re_search=1 with more copies had greater levels of enzymes and produced an increased amount of amino acid tryptophan in comparison to the unmodified counterparts.

The researchers also found that the hybrids with transgenic genes had greater rates of photosynthesis, grew more shoots and flowers and produced 48 to 125 percent more seeds per plant than non-transgenic hybridswithout the use of glyphosate.

Lu believes that making the rice weedy less competitive might make it harder for farmers who have their land invaded by pests.

Brian Ford Lloyd, a UK plant scientist, said that the EPSP Synthase gene could get in wild rice varieties. https://www.amazon.co.jp/%E6%97%A5%E7%94%A3%E5%8C%96%E5%AD%A6-%E9%99%A4%E8%8D%89%E5%89%A4-%E5%8E%9F%E6%B6%B2%E3%82%BF%E3%82%A4%E3%83%97-%E3%83%A9%E3%82%A6%E3%83%B3%E3%83%89%E3%82%A2%E3%83%83%E3%83%97%E3%83%9E%E3%83%83%E3%82%AF%E3%82%B9%E3%83%AD%E3%83%BC%E3%83%89-500%EF%BD%8D%EF%BD%8C/dp/B001GH6XVQ would erode the genetic diversity of their species, which is extremely vital. "This is one of the clearest examples of highly plausible negative impacts [of GM crops on the environment."

The public believes that genetically modified plants that have more copies of their own genes than those from microorganisms are more safe. This belief is also challenged by the study. Lu declares that "our study is not proving that this is the case."

Some researchers believe this finding calls for a review of future regulation of crops that have been genetically modified. Ellstrand believes that some believe that biosafety regulations could be relaxed given the past more than two years of genetic engineering. "But the study proved that the new technologies still require careful evaluation."
