Iron regulation modules in the context of Fe resource allocation, seed sink strength and evolution in Arabidopsis thaliana

Soil is enriched with various minerals. Iron (Fe) is one of the most abundant elements on Earth. Also, Fe is an essential microelement required by plants. However, high levels of Fe uptake lead to cellular toxicity in plants. Thus, in plants, the processes of Fe uptake, allocation to various organs and tissues and utilization is precisely regulated via Fe-regulated transcription factors. The underlying mechanisms of this complex regulatory network are still elusive. In this project we will study at the mechanistic level how Fe resource allocation is triggered by the Fe regulation cascade and sink strength and the evolution of the Fe regulation modules in seed plants.
