Topic: "Investigating the physiological, biochemical, and molecular responses of maize to con-current biotic and abiotic stresses"

Project context

The PhD position is embedded in the DFG Research Unit
"MultiStress - Concurrent multiple abiotic and biotic stress interactions in maize: impacts and mecha-nisms" (RU 6101).

The MultiStress Research Unit investigates how maize responds to interacting abiotic stresses (e.g. drought, nitrogen deficiency, heat) and biotic stresses (e.g. foliar disease or herbivory), and how these interactions affect plant performance across environments. The project follows an integrated experi-mental approach across laboratory, greenhouse, and field scales, combined with advanced phenotyping and data-driven analysis.

This PhD project is part of Subproject 2 (SP2), which aims to provide a mechanistic understanding of maize multistress responses at the physiological, biochemical, and molecular levels. SP2 focuses on plant water relations, hormonal regulation (with emphasis on abscisic acid), oxidative stress responses, and their integration with high-resolution phenotyping under single and combined stress conditions. Coor-dinated field experiments will be conducted in Germany and Kenya, offering an international research context.
The position will be hosted at TUM, within a highly interdisciplinary and international research environ-ment, and involves close collaboration with partners at the University of Göttingen and Kenyan research institutions.

Main tasks

• Conducting laboratory, greenhouse, and field experiments on maize under single and combined abi-otic and biotic stress conditions
• Measuring physiological traits such as gas exchange, transpiration, leaf water potential, and chloro-phyll fluorescence
• Biochemical analyses including phytohormones (ABA), reactive oxygen species (ROS), and antioxi-dant enzyme activities
• Molecular analyses related to ABA signalling, including protoplast- based functional assays
• Integration of physiological and biochemical data with advanced phenotyping approaches (e.g. ther-mal imaging)
• Statistical analysis and interpretation of multi-factorial datasets
• Active collaboration with other subprojects within the MultiStress Research Unit
• Publication of research results in international peer-reviewed journals

Required qualifications

• Master’s degree (or equivalent) in plant sciences, biology, crop science, environmental sciences, or a related field
• Strong interest in plant stress physiology and crop responses to environmental variability
• Experience with experimental plant research
• Ability to work independently as well as collaboratively in an interdisciplinary and international team
• Very good command of English, both written and spoken

Preferred experience and skills (not mandatory)

• Experience with plant water relations, plant hydraulics, or hormone signalling
• Biochemical or molecular biology techniques
• Experience with imaging, phenotyping, or data-driven analysis
• Willingness to participate in field experiments, including research stays abroad (Kenya)

We offer

• A four-year PhD position (65% TV-L E13) within a DFG-funded Research Unit
• An interdisciplinary, collaborative, and internationally visible research environment at TUM
• Close supervision and training in experimental design, data analysis, and scientific writing
• Access to state-of-the-art laboratory, phenotyping, and imaging infrastructure
  o Opportunities for international collaboration and participation in conferences and project workshops
