Anderson, Mattoon et al. exposed the C4 model plant green foxtail Setaria viridis to four-hour periods of high light or high temperature and observed transcriptomic, photosynthetic, and ultrastructural changes. Both treatments caused a comparable reduction in photosynthetic efficiency, but the authors identified important differences in key pathways and differential responses in the mesophyll and bundle sheath cells in response to these two treatments.
