Associate Professor Sixue Chen was awarded a 4-year NSF grant for his research on metabolomics of plant stomatal movement. The award totaling 1.5 million dollars funds a collaborative project between Chen Lab and Assmann lab at PennState University. The research team plans to use modern biological tools including mass spectrometry to investigate the functions of metabolites in the processes of red light and carbon dioxide (CO2) regulated stomatal movement at the plant leaf surface.
