"For as long as crops have been domesticated, farmers have been selecting seed from the best performing plants; based primarily on their yield and relative performance. In some cases, a plant may experience stress during the season, whether from disease, drought, or insects. Many times that plant will recover and still produce a decent yield, and possibly provide seed for planting the following year. It’s a system that has worked relatively well for a long time. But this system depends on the idea that if a plant experiences stress and survives, it won’t pass a memory of the stress on to its offspring. Farmers and researchers have made the assumption that the impacts of stress on a plant remain in the current generation and don’t make an imprint into the next generation. But recent research suggests that this might not be true."
