High light and temperature reduce photosynthetic efficiency through different mechanisms in the C4 model Setaria viridis
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.
