Untitled. Untitled. Disadvantages and Advantages of Genetically Modified Crops | Samsung Galaxy Blog. Nearly 90 percent of all the crops grown in the United States have been touched by science. Genetically modified organisms, or GMOs, are plants that have had their genes manipulated. They give the crops new characteristics, like insect resistance, larger yields, and faster growing traits. The use of GMOs is hardly new, but many believe that sufficient research on the long term effects has not been conducted.
In order to understand more about genetically modified crops let’s take a look at the pros and cons. The Advantages of Genetically Modified Crops 1. Better For The Environment Since GMOs require much less chemicals to thrive, the impact on the environment is lessened. 2. 3. 4. 5. 6. The Disadvantages of Genetically Modified Crops 1. 2. 3. 4. Want to learn how to become a professional blogger and never have to get a job? Important Facts About Genetically Modified Crops The fight to have GMO foods labeled is very heated right now.

Throwing Biotech Lies at Tomatoes - Part 1: Killer Tomatoes | The Huffington Post. Remember the pictures of the fish tomatoes? For years they were an unofficial emblem of the anti-GMO movement. They depicted how anti-freeze genes from an Arctic fish were forced into tomato DNA, allowing the plants to survive frost. Scientists really did create those Frankentomatoes, but they were never put on the market. (Breyers low-fat ice cream, however, does contain anti-freeze proteins from Arctic fish genes, but that’s another story.) The tomato that did make it to market was called the Flavr Savr, engineered for longer shelf life. Fortunately, it was removed from the shelves soon after it was introduced. Although there are no longer any genetically modified (GM) tomatoes being sold today, the FDA’s shady approval process of the Flavr Savr provides a lesson in food safety—or rather, the lack of it—as far as gene-spliced foods are concerned.
Bleeding stomachs Calgene tested two separate Flavr Savr tomato lines. Oh yeah, some rats died. Genetically modified tomato - Wikipedia. A genetically modified tomato, or transgenic tomato, is a tomato that has had its genes modified, using genetic engineering. The first commercially available genetically modified food was a tomato engineered to have a longer shelf life (the Flavr Savr). Currently there are no genetically modified tomatoes available commercially, but scientists are developing tomatoes with new traits like increased resistance to pests or environmental stresses. Other projects aim to enrich tomatoes with substances that may offer health benefits or be more nutritious.
As well as aiming to produce novel crops, scientists produce genetically modified tomatoes to understand the function of genes naturally present in tomatoes. Background Examples Delayed ripening Scientists in India have delayed the ripening of tomatoes by silencing two genes encoding N-glycoprotein modifying enzymes, α-mannosidase and β-D-N-acetylhexosaminidase.
