coincidencia? To create “Roundup Ready” plants, Monsanto cloned a gene from a form of agrobacterium found growing at a Roundup factory. Researchers found that this particular bug’s amino production was not affected by glyphosate, and they used E. coli to clone the gene responsible for this trait. Then they used a different agrobacterium — the familiar A. tumefaciens — to stick the gene into the chromosomes of plants. The plants that have the bacteria’s gene are still able to produce the three amino acids, and they survive just fine.
