Schematic diagram showing average annual atmospheric [CO2] level for 2021 and the effect of rising night temperature (Tmin) on rice productivity by enhanced respiration: photosynthesis ratio (RN/A) resulting in augmented release of carbon at the cost of biomass and yield in conventional genotypes. On the contrary, introgression of CO2-responsiveness trait in C3 crops facilitates enhanced carbon sequestration and allocation of additional carbon into biomass, and compensating Tmin-induced carbon losses. LCR, least CO2-responsive; HCR, high CO2-responsive.
