What is Roundup Readiness? ラウンドアップ is a trademark name used to describe a patent-pending line of genetically modified crop seeds that are immune to the herbicide that is based on glyphosate called Roundup. These are referred to as Roundup Ready crops.
Who came up with Roundup?
ラウンドアップ , Monsanto chemical chemist and first to discover that Roundup's active agent was glyphosate in the year 1970, was the first to identify it as a herbicide. The majority of herbicides used in the ag business were pre-emergent. That means they were applied prior to the crops and weeds emerged. Glyphosate's post-emergent function in the control of large quantities of broadleaf weeds and grass plants was different. This, combined with its extraordinary environmental properties (soil activation rapid decay, zero carry-over etc.) and toxicological characteristics (extremely low toxicity for mammals and beneficial organisms) this made the product a breakthrough.
When was the Roundup first created?
Roundup(r) initially introduced in 1974 to the market as a broad-spectrum insecticide it quickly became a major worldwide agricultural chemical. Roundup(r) initially, was utilized in ditches along railway tracks as well as in fields between the growth seasons. This enabled ranchers and farmers to control grass and broadleaf plants that had emerged out of the soil.
The next step was Roundup Ready GMOs.
Monsanto scientists recognized the potential benefits Roundup(r) which is a recombinant DNA product, might bring to farmers following the technological breakthroughs of the 1970s. The challenge was first tackled by a small group of scientists headed by Dr. Ernie Jaworski (Rob Horsch and Steve Rogers), The first systems to introduce gene into the plant were developed by this group in the early 1980s. After that we turned our attention to developing virusesresistant and insect-resistant and Roundup-resistant crops.
It was established that Roundup glyphosate inhibited plants' capacity to make aromatic amino acids. Roundup's high level of mammalian safety is because of this. ラウンドアップ is also rapidly broken down in the soil by microorganisms. In the mid-1980s our scientists had discovered plants and microbial genes that conferred increased herbicide tolerance through laboratory testing. In 1987 the USDA authorized the first field test for Roundup Ready plants. ラウンドアップ was a genetically altered version of tomato plants that were resistant to Roundup. A few years later, Roundup Ready trait, which was the bacteria genetic that was isolated, was introduced to other crops.
Let's consider soybeans as an illustration. The first step is to answer two questions. What are Roundup Ready soybeans and how do they get made? Roundup Ready soybeans can be genetically engineered in order to be resistant to Roundup, the herbicide. This soybean is tolerant to Roundup because every seed is equipped with the Roundup Ready gene infected before it is planted. This means that farmers can spray their fields with the herbicide and not kill their crop.
Roundup Ready crops, which were first introduced in 1996, changed agricultural research and agriculture. Roundup resistance was immediately accepted by farmers, and adoption was quick. Today, more than 90 percent of U.S. soybeans are grown using a biotech gene for herbicide tolerance. https://search.rakuten.co.jp/search/mall/%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/ simplified and improved weed management systems. This has led to higher yields on crops. It also reduced tillage, reduced equipment costs and made harvesting more efficient due to fewer the amount of weeds. One of the environmental benefits has been the rise in the use of conservation cultivation: farmers can reduce the amount of energy used as well as GHG emissions, and also improve soil structure while preserving soil structure. ラウンドアップ 口コミ was equivalent in 2013 to the removal of 28.3 billion tonnes of carbon dioxide (or 12.4 million vehicles) off the roads.
