...hat protects it from oxidative damage as the metal crosses the cell." In this study, Salt and his colleagues sampled a number of closely related plants that grow on soils naturally enriched in nickel. These plants ranged from those that didn't accumulate any nickel to the hperaccumulators that built up almos...Improving crops without genetic modification natural variation holds the key
