Elevated carbon dioxide offers promise for wheat adaptation to heat stress by adjusting carbohydrate metabolism.

ABSTRACT: Carbohydrate metabolism in plants is influenced by thermodynamics. The amount of carbon dioxide (CO₂) in the atmosphere is expected to rise in the future. As a result, understanding the effects of higher CO₂ on carbohydrate metabolism and heat stress tolerance is necessary for anticipating plant responses to global warming and elevated CO₂. In this study, five wheat cultivars were exposed to heat stress (40 °C) at the onset of anthesis for three continuous days. These cultivars were grown at two levels of CO₂ i.e. ambient CO₂ level (a[CO₂], 380 mmol L^-1) and elevated CO₂ level (e[CO₂], 780 mmol L^-1), to determine the interactive effect of elevated CO₂ and heat stress on
