Notes

How did Roundup Ready or Roundup get their names?
What is Roundup Ready? Roundup Ready is a trademark that refers to a type of genetically engineered seeds that are resistant to Roundup. These plants are also known as Roundup Ready crops.

Roundup, then, was it really made up?
John Franz (Monsanto Chemist) first identified Glyphosate as a herbicide within Roundup. Pre-emergent herbicides were used in the ag industry in the early days. They were applied before the crops or weeds emerged. Glyphosate's extraordinary post-emergent capability in controlling large numbers herbicides for broadleaf and grass was something quite unique. ラウンドアップ Its combination with its exceptional environmental (soil destruction rapid degradation and no carryover) as well as toxicological (extremely small toxicity to mammals, beneficial organisms and beneficial organisms, etc.), was what made it a revolutionary product.

When was Roundup first created?
Roundup(r), a broad-spectrum herbicide was first introduced to the market in 1974. It quickly became become the top-selling agricultural chemical. It was initially employed in ditches, along railroad tracks and sprayed on fields between growing seasons. This helped farmers control grass and broadleaf weeds that grew from the soil, thereby decreasing the need for tillage, preserving soil structure, and reducing soil erosion.

Next came the case of Roundup Ready GMOs.
Inspired by the groundbreaking developments in Recombinant DNA technology in the 1970s, Monsanto scientists recognized the numerous advantages for farmers who benefited if Roundup(r) could be directly applied to their crops to control weeds within their fields. A small team of scientists (Rob Horsch, Steve Rogers and myself) under the direction of Dr. Ernie Jaworski, began working on this issue. In the early 1980s this team had developed the first methods to introduce genes in plants. Our focus shifted to the creation of virus-resistant crops, which are resistant to insects and also Roundup.

It was well-known that Roundup could inhibit the biochemical pathway that plants use to make aromatic amino acids. Roundup's high-level of protection for humans and mammals is due to the fact that glyphosate has the ability to be broken down quickly by soil microorganisms. Our researchers discovered both microbe and plant genes that conferred resistance to herbicides. ラウンドアップ The USDA approved the first field testing of Roundup Ready plants in 1987. ラウンドアップ 藤 It was a Roundup-resistant tomato crop that was derived by the genetically altered tomato plant. They were also tolerant to Roundup. After a few years, the bacterial gene that would later become the Roundup Ready trait was isolated and introduced into crops.

Let's take a look at soybeans as an example, by addressing the questions: what are Roundup Ready soybeans? And how are Roundup Ready soybeans constructed? Roundup Ready soybeans are soybeans genetically engineered which have had their DNA changed so that they can withstand Roundup's herbicide, glyphosate. This soybean is intolerant to Roundup as each seed has the Roundup Ready gene infected before it's planted. This permits farmers to spray their fields with herbicides, without having to kill their crops.

Roundup resistance was instantly acknowledged by farmers and widespread adoption occurred. Today, more than 90 percent of U.S. soybeans and cotton use Roundup Ready crops. Roundup Ready crops simplified and improved the effectiveness of weed control methods. This led to increased yields of crops. Also, it reduced tillage, reduced equipment costs and made harvesting simpler due to less the amount of weeds. One of the major environmental benefits is the growing use of conservation tillage. Through the reduction of plowing, farmers have reduced their energy use and emissions of GHG while maintaining soil structure and decreasing erosion. This was equivalent of taking away 28.4 Billion kg carbon dioxide from the atmosphere, equivalent to 12.4 M vehicles off the road for one year (Source . PG Economics.
