Article Synopsis
- Iron (Fe) homeostasis plays a crucial role in root growth by influencing the production of reactive oxygen species (ROS) and their distribution at root tips.
- The presence of excess Fe triggers an increase in ferritin, which helps to store Fe and protects plants from oxidative stress, particularly in the root's meristematic zone where ferritin genes AtFer1 and AtFer3 are expressed.
- In mutants lacking ferritin, excess Fe negatively affects lateral root length and density more severely, suggesting that the balance of ROS and regulation by the UPB1 transcription factor is key to understanding how Fe impacts root system architecture.
Iron (Fe) homeostasis is integrated with the production of Reactive Oxygen Species (ROS) whose distribution at the root tip participates in the control of root growth. Excess Fe increases ferritin abundance, enabling the storage of Fe which contributes to protection of plants against Fe-induced oxidative stress. AtFer1 and AtFer3 are the two ferritin genes expressed in the meristematic zone, pericycle and endodermis of the Arabidopsis thaliana (Arabidopsis) root, and it is in these regions that we observe Fe stained dots.
