# Imaging of labile Fe2+ and Fe3+ in living Arabidopsis thaliana roots

## TL;DR

This paper introduces a method to image iron in living plant roots, showing how iron exists in different forms in different parts of the plant.

## Contribution

The study adapts fluorescent imaging to visualize labile Fe2+ and Fe3+ in living Arabidopsis roots.

## Key findings

- Fluorescent imaging reveals heterogeneous iron redox status in plant tissues.
- Labile Fe2+ and Fe3+ pools are spatially distinct in Arabidopsis roots.

## Abstract

Adapting fluorescent iron imaging to living plants enables visualizing labile Fe2+ and Fe3+ pools, revealing the heterogeneous distribution of iron redox status at the tissue and cellular levels.
