Metabolic Pathways Involved in Carbon Dioxide Enhanced Heat Tolerance in Bermudagrass.

ABSTRACT: Global climate changes involve elevated temperature and CO₂ concentration, imposing significant impact on plant growth of various plant species. Elevated temperature exacerbates heat damages, but elevated CO₂ has positive effects on promoting plant growth and heat tolerance. The objective of this study was to identify metabolic pathways affected by elevated CO₂ conferring the improvement of heat tolerance in a C₄ perennial grass species, bermudagrass (Cynodon dactylon Pers.). Plants were planted under either ambient CO₂ concentration (400 μmol⋅mol^-1) or elevated CO₂ concentration (800 μmol⋅mol^-1) and subjected to ambient temperature (30/25°C, day/night) or heat stress (45/40°C, day/night).
