We focus on the molecular regulation of iron homeostasis in plants and their adaptations on the abiotic stress of iron deficiency. The key regulator of iron uptake in A. thaliana is the basic helix-loop-helix protein FER-LIKE IRON DEFICIENCY INDUCED TRANSCRIPTION FACTOR (FIT). Within my research project I would like to investigate in which way covalent modifications influence FIT action, which could possibly activate, deactivate or fine-tune the plant responses to different iron supply conditions. By using a phospho-mimicking approach, I will investigate putative phosphorylation sites to analyze whether and in which way these mutations affect protein function and regulation and hence iron acquisition from the soil.
