Researchers identify genetic variants that help plants grow in low-iron environments, which could improve crop yields

Just like people, plants need iron to grow and stay healthy. But some plants are better at getting this essential nutrient from the soil than others. Now, a study led by a researcher at the Salk Institute has found that variants of a single gene can largely determine a plant`s ability to thrive in environments where iron is scarce.
