First, what exactly is ラウンドアップ and what are the Roundup Ready crops? Roundup Ready is a trademark name for a patent-pending line of genetically modified seeds that are immune to the herbicide glyphosate, Roundup. These plants are also known as Roundup Ready crops.
Who came up with Roundup?
John Franz, Monsanto's chemist who first discovered Glyphosate as an herbicide in Roundup in the year 1970. The majority of herbicides available at that period were preemergent. They were used before the growth of the crop and the weeds. Glyphosate's remarkable post-emergent ability in preventing the spread of large amounts of herbicides for broadleaf and grass was unique. Its combination with its extraordinary environmental (soil destruction, rapid degradation and no carry-over) and toxicological (extremely low toxicity to mammals, beneficial organisms as well as beneficial organisms.) which created a product that was revolutionary.
What year was it when Roundup first launched?
ラウンドアップ (r) was introduced on the market in 1974 as a broad-spectrum herbicide and quickly became one of the top agricultural chemicals on the market. Roundup(r) was initially applied on railway tracks, in ditches, as well as on fields in between the growing seasons. This allowed farmers to keep weeds out of the broadleaf grass that emerged from the soil, thereby lessening the need to tillage, preserving soil structure and reducing erosion.
The next step was Roundup Ready GMOs.
Monsanto scientists, inspired by the amazing advancements in recombinant technology in the 1970s recognized the many benefits for farmers if Roundup could be directly applied to their crops in order to reduce the weeds. https://shop.takii.co.jp/products/detail/MSH992 , Rob Horsch, Steve Rogers, and I began working on this problem. By the early 1980s, this team had developed the first techniques to introduce particular genes into plants. Eventually, our focus was on the development of virus-resistant insects resistant, Roundup-tolerant plants.
It was widely known that Roundup can block the biochemical pathway that plants use to create aromatic amino acids. Roundup's high level protection for humans and mammals is due to the fact that glyphosate is able to be rapidly broken down by soil microorganisms. Our researchers discovered both microbe and plant genes that conferred resistance to herbicides. The USDA approved the first field testing of Roundup Ready plants in 1987. The Roundup-resistant plant included genetically altered tomatoes that proved resistant to Roundup. After ラウンドアップ , the Roundup Ready gene was isolated and identified.
Let's take soybeans as an example. We first need to address two issues. What is ラウンドアップ ? How do they get made? Roundup Ready Soybeans are soybeans genetically engineered which have had their DNA altered so that they can withstand the herbicide glyphosate that is the active component in the herbicide Roundup. This soybean is intolerant to Roundup since every seed is equipped with the gene that is afflicted with Roundup before it's planted. ラウンドアップ 古い permits farmers to spray their fields with Roundup Ready herbicides to destroy weeds but not the crops.
It is clear the fact that Roundup Ready crops were introduced in 1996 and transformed agriculture and agricultural science. Roundup resistance soon was a favored crop in the U.S. More than 90% of U.S. soybeans and cotton, corn, and canola farms now employ this biotech trait. Roundup Ready crops helped to make it easier and more efficient for the weed control systems. They also allowed for greater yields from crops. ラウンドアップ has had significant environmental benefits. Farmers have decreased their energy usage and GHG emissions through the use of smaller plowing. http://www.ihs-agri.jp/nouyaku/hatasaku-josou/hatasaku-josou-keiyou/josou101090010301.html preserves soil structure and reduces erosion. This was equivalent in 2013 to the removal of 28.3 billion tonnes of carbon dioxide (or 12.4 million cars) off the roads. Source: PG Economy.
