Effect of elevated CO2 on plant growth, active constituents, and production

Rapeseed plant: biostimulation effects of plant growth‐promoting Actinobacteria on metabolites and antioxidant defense system under elevated CO2 conditions

“…Drawing on an increasing range of primary carbon sources, researchers have reported different experiments in which plant production, growth, development and metabolism were affected dramatically, particularly when nutrients and water have been sufficiently available to the plant. [4][5][6] Moreover, eCO 2 conditions not only resulted in more photosynthesis but also increased the allocation of photosynthetic C to root tissue. 2,7 There have been several investigations into the causes of inducing plants' stress tolerance under eCO 2 conditions by modifying the carbon and nitrogen metabolism, which is mainly expressed by reduced oxidative damage and stress-generated reactive oxygen species (ROS) levels, and increased osmoprotectant and antioxidant contents under eCO 2 .…”

“…Along with these challenges, there is increasing concern over the responses of plants to elevated atmospheric CO 2 (eCO 2 ). Drawing on an increasing range of primary carbon sources, researchers have reported different experiments in which plant production, growth, development and metabolism were affected dramatically, particularly when nutrients and water have been sufficiently available to the plant 4‐6 . Moreover, eCO 2 conditions not only resulted in more photosynthesis but also increased the allocation of photosynthetic C to root tissue 2,7 .…”

Physiological and biochemical responses of wheat to synergistic effects of selenium nanoparticles and elevated CO2 conditions

“…), forest fires, heavy rain, and heat waves ( AbdElgawad et al., 2014 ). As a result, elevated CO 2 (eCO 2 ) is increasingly recognized as a main factor affecting global crop production, because an increase in primary carbon sources influences crop growth, biomass production, the photosynthesis cycle, and metabolite profiling differently and significantly, even in non-stressed plants ( Jing et al., 2016 ; Kaur et al., 2023 ). In recent years, there has been an increasing amount of literature on the responses of wheat plants to elevated atmospheric CO 2 through improving photosynthesis capacity, declining transpiration and water use, and resulting in a productive advantage and higher grain yield ( Ainsworth and Rogers, 2007 ).…”
