... Nessler, head of plant physiology, pathology, and weed science at Virginia Tech, has found that by transferring certain rat genes into lettuce, he can turn on the plants latent Vitamin-C-producing pathway. In laboratory experiments using that process, he increased the level of Vitamin C in lettuce by 700...Nile crocodiles threatened by alien weed
