How exactly is the beet H7-1 beet genetically modified? Is a plasmid added to the DNA?

AExpert Answer

Roundup Ready sugar beets H7-1 was developed by first making a piece of DNA, called an expression cassette, that contains the cp4 epsps gene for tolerance to the herbicide glyphosate, which is the active ingredient in Roundup agricultural herbicides. Using genetic-engineering techniques, that expression cassette is spliced into a plasmid and transformed into Agrobacterium. The Agrobacterium is then added to a petri dish containing sugar beet cells growing in tissue culture. The Agrobacterium uses a natural process to insert that expression cassette into the genome of the plant. The DNA of the resulting plant then contains the cp4 epsps gene and has a tolerance to glyphosate. The process is not unique to sugar beets and is used to develop most GM plants. A detailed description of the process is available in the USDA petition, starting on page 19: http://www.aphis.usda.gov/brs/aphisdocs/03_32301p.pdf

 

There are also several YouTube videos that show the basic process for making GM plants using the Agrobacterium method.

The short answer is no, neither MSG or animal extraction are from GMOs, nor is MSG, animal extraction, or animal products/animal DNA in GMOs.   When people refer to Genetically Modified Organisms (GMOs), they are referring to precision plant breeding using genetic engineering (also called GE). It allows plant breeders to take a desirable trait (like resistance to drought, insects, weeds, and disease) from one plant or organism and transfer it to the plant...

No. MSG, monosodium glutamate, is a chemical additive, certainly not a GMO.

Monosodium glutamate is mainly produced by a fermentation process with sugar as a starting material. It is not GMO. Plants that have been genetically modified do not contain any animal residue or byproducts.
