If farmers could plant crops designed to exploit these genes, they could theoretically produce food with more nutrients while using less fertilizer by making plants pull minerals from soil more efficiently, Salt said. They also could use plants to mop up toxins. For markets in richer nations, Salt is partnering with a company called NuCycle Therapy to develop selenium-rich plants, because that compound has been found to fight cancer. Likewise, many people in developing nations suffer from "hidden hunger," Salt said. They lack important vitamins in their diet even though they get enough calories. He hopes his technology will address that need.
