Adaptive potential of iron (Fe) management in Arabidopsis thaliana in alkaline calcareous soils (A08)

• Subject Area: Plant Physiology
• Term: since 2022
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 456082119

Over 30% of soils available for plant growth are alkaline calcareous soils with high pH restricting the availability of iron (Fe), a crucial nutrient in plants. This project will use a large panel of A. thaliana genotypes and mutants to identify genetic variants impacting and improving plant growth in calcareous soil with a focus on the role of iron acquisition and allocation. The project will further explore how the identified genetic variants for Fe management affect tolerance to other nutrient limitations and plant-plant competition. Ultimately, we will elucidate how the plants dynamically adjust Fe homeostasis throughout the life cycle under varying nutrient availabilities and environmental challenges.
