How plants protect themselves from oxidative stress during iron uptake — and why this is also important for humans

Iron is a critical micronutrient for the survival of plants and humans, yet too much iron can also be toxic. An interdisciplinary research team has discovered that the protein PATELLIN2 is not only involved in regulating iron levels in plants. PATELLIN2 is one of a group of proteins that are also involved in the transport of vitamin E in humans. The results are also important for supplying people with iron via plant foods.
