I grew up in southeast Arkansas and worked on farms every summer. My passion for agriculture led to earning a Ph.D. in Microbiology from the University of Georgia studying the interaction of soil bacteria with plants. After a post-doctoral fellow at the University of Minnesota, I worked as a biotechnologist at USDA. At Monsanto, I’ve worked as a Regulatory Affairs Manager for 17 years on various corn, cotton, potato, alfalfa, and sugar beet products.

A: 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... Continue Reading
Q: My question pertains to the genetic modification of Roundup Ready soybeans. How is it that this process occurs? Id like to know the specific steps used from the targeting of specific genes at the start to the finished product. Thank you

A: The basic steps are as follows: Identify a gene that will provide resistance to the herbicide.Based on the sequence of the resistant gene, make a DNA expression cassette that contains a promoter to turn on the gene, the resistant gene, and a sequence to stop gene transcription. Transform the plant in tissue culture to incorporate the resistant geneScreen for plants that have successfully incorporated the resistant gene and are tolerant to glyphosate.A very good detailed description...

Q: After eliminating GMOs from my diet, I intuitively can tell when I accidently eat gmos. I get a specific "sluggish feeling." Humans used mercury to harvest gold because we did not know better. Life is complex. We live in relationship...

A: Based on your question, it seems that you are skeptical about the intentions and awareness of those of us who have dedicated our lives to researching and developing GM crops. I’d like to address your question based on my personal experience. I grew up in southeastern Arkansas, in a small farming town named Dumas, where my grandfather, uncles and cousins were and still are farmers. I worked in the cotton fields every summer, scouting for insect pests so farmers knew when to apply... Continue Reading
Q: When did your company, or any company or individual connected with Monsanto, begin the practice of genetic modification? What were some of the first things genetically modified and for what purpose?

A: First, let me mention that details on the history of crop modification can be found in the Explore section of GMO Answers: http://gmoanswers.com/explore And, as described on the “History of Crop Modification” page, plants have been genetically modified through conventional breeding for centuries. The first use of biotechnology involving transformation and recombinant DNA technology, or what is commonly referred to as GMO, at Monsanto was research work with E. coli for producing...
