Plant studies reveal how, where seeds store iron

re, which funded the research. "The discovery that iron localizes in specific parts of a seed opens the possibility of developing seed crops such as grains and beans with increased content of this important nutrient."

The findings reveal how essential it is to look beyond ferritin to understand how iron is stored by plants. The researchers say the stored iron in the vacuole is a key source of iron for developing seedlings. Seedlings that do not express the VIT1 protein grow poorly when iron is limited.
