The iron deficiency response in Arabidopsis thaliana requires the phosphorylated transcription factor URI [Plant Biology]

Iron is an essential nutrient for plants, but excess iron is toxic due to its catalytic role in the formation of hydroxyl radicals. Thus, iron uptake is highly regulated and induced only under iron deficiency. The mechanisms of iron uptake in roots are well characterized, but less is known about...
