Global ecology of C4 grasses

Global ecology of C4 grasses

C4 photosynthesis is a physiological innovation that evolved in more than 20 lineages of grasses, which today dominate 20% of the global land surface. Our comparative experiments investigate how this physiological innovation changed growth and allocation patterns. We also investigate the mechanisms driving the worldwide assembly of grassy biomes 10 myr ago, looking at the interactions between C4 photosynthesis, other plant traits and environmental change.
