Integrating transcriptomic and physiological measurements to reveal gene regulatory networks coordinating photosynthesis and nitrogen use.
A relationship between photosynthesis and nitrogen use has been recognized at a physiological level for decades, but how these two important metabolic pathways are coordinated is poorly understood. Advances in DNA-sequencing technologies now present opportunities to revisit how these two processes interact at a regulatory level. Using a systems biology approach that combines genomics, phenotyping, and computational biology, the three main objectives driving my research are to:
- Define the molecular factors involved in coordinating photosynthesis with nitrogen availability.
- Identify natural genetic variation influencing crosstalk between photosynthesis and nitrogen use.
- Bridge basic and applied research by transferring knowledge from data-rich model species to crops.
Improving our understanding of how genetic and environmental factors influence the coordination of photosynthesis and nitrogen assimilation will help identify strategies for improving nitrogen use efficiency. This is an important goal because nitrogen fertilizer production is a significant source of greenhouse gas emissions, and climate change will in turn impact photosynthesis and crop yield. At a fundamental level, this work will also contribute to understanding the basic principles underlying how cellular networks process complex environmental signals.
