“…The stress-mitigating effects of elevated CO 2 on P n was not due to changes in stomatal limitations which suggests the promotive effects may be on non-stomatal or biochemical aspects of P n . Elevated CO 2 concentration has been shown to increase carboxylation rate of ribulose carboxylase/ oxygenase enzyme (Rubisco) or alleviation of metabolic limitations controlling photosynthesis in some plant species (Yelle et al, 1989;Yu et al, 2014). The alleviation of salt-indced metabolic limitations on P n was mainly through the increase in electron sink capacity (Pérez-López et al, 2012).…”

“…Excessive salinity in the soil can cause osmotic and ionic stresses, leading to various growth and physiological damages to plants (Munns et al, 1999;Pessarakli, 2007Pessarakli, , 2010. The atmospheric CO 2 concentration has been rising and is expected to double by the year 2100, which may mitigate the adverse effects of various abiotic stresses, including salinity stress (Kirkham, 2011;Munns et al, 1999) for various plant species, including several coolsason turfgrass species (Song et al, 2014;Yu et al, 2012aYu et al, ,b, 2014. However, mechanisms of elevated CO 2 affecting plant responses to salinity stress are not completely understood.…”

“…Several other genes involved in carbon fixation and assimilation also declined in transcript level in response to elevated CO 2 (550 to 800 vs. 280 to 400 mmol mol -1 ), such as rubisco activase, ribulose-phosphate 3-epimerase (converting D-ribulose 5-phosphate into D-xylulose 5-phosphate in the Calvin reductive pentose phosphate cycle), and ribose-phosohate isomerase (catalyzing the conversion between ribose-5-phosphate and ribulose-5-phosphate in both the pentose phosphate pathway and the Calvin cycle; Supplemental Table S3; Kontunen-Soppela et al, 2010b;Leakey et al, 2009;Ludewig and Sonnewald, 2000;Takatani et al, 2014). At the enzymatic level, both increases (720 or 800 vs. 360 or 400 mmol mol -1 ; Vu et al, 2006;Yu et al, 2014) and decreases (987 or 1100 vs. 355 or 350 mmol mol -1 ; Bae and Sicher, 2004;Maroco et al, 1999) in activity of Rubisco were reported under elevated CO 2 .

Increases in atmospheric CO2 concentration have exerted significant impacts on plant growth. Numerous studies have reported positive effects of elevated CO2 on plant growth and adaptation to various environmental stresses in many plant species. The mechanisms by which CO2 enrichment regulates plant growth and stress adaptation are not completely understood. There have been some recent exciting advances in elucidating the cellular, metabolic, and molecular basis for increased growth under elevated CO2. At the cellular level, cell growth involving both cell division and cell expansion is stimulated by increasing CO2, which has been associated with increased photosynthetic activities and carbohydrate availability, and also with the expression of genes controlling cell division, cycling, and cell expansion. Proteomic profiling studies identified CO2–regulated proteins mainly involved in photosynthesis, carbon metabolism, energy pathways, molecular chaperones, and antioxidant proteins. Transcriptomic analyses identified several hundreds of genes responsive to elevated CO2 levels, which play roles in cell wall loosening, photosynthesis, respiration, water use, and protein synthesis, as well as stress defense. This paper reviews recent progress in the mechanistic understanding of CO2 regulation of plant growth and stress adaptation at the cellular, metabolic, and molecular levels, and addresses research gaps and future research perspective areas.

Grasslands cover more than 70% of the world's agricultural land playing a pivotal role in global food security, economy, and ecology due to their flexibility and functionality. Climate change, characterized by changes in temperature and precipitation patterns, and by increased levels of greenhouse gases in the atmosphere, is anticipated to increase both the frequency and severity of extreme weather events, such as drought, heat waves, and flooding. Potentially, climate change could severely compromise future forage crop production and should be considered a direct threat to food security. This review aimed to summarize our current understanding of the physiological and metabolic responses of temperate grasses to those abiotic stresses associated with climate change. Primarily, substantial decreases in photosynthetic rates of cool‐season grasses occur as a result of high temperatures, water‐deficit or water‐excess, and elevated ozone, but not CO2 concentrations. Those decreases are usually attributed to stomatal and non‐stomatal limitations. Additionally, while membrane instability and reactive oxygen species production was a common feature of the abiotic stress response, total antioxidant capacity showed a stress‐specific response. Furthermore, climate change‐related stresses altered carbohydrate partitioning, with implications for biomass production. While water‐deficit stress, increased CO2, and ozone concentrations resulted in higher carbohydrate content, the opposite occurred under conditions of heat stress and flooding. The extent of damage is greatly dependent on location, as well as the type and intensity of stress. Fortunately, temperate forage grass species are highly heterogeneous. Consequently, through intra‐ and in particular inter‐specific plant hybridization (e.g., Festuca x Lolium hybrids) new opportunities are available to harness, within single genotypes, gene combinations capable of combating climate change.
