Can improvement in photosynthesis increase crop yields? (2006, result): “…the selection of forms of Rubisco with increased k c c and decreased τ is consistent with the observation that Rubisco from C 4 plants, in which the enzyme functions in a high [CO 2 ], typically has a higher k c c and lower τ than in C 3 land plants (Seemann, Badger & Berry 1984; Sage 2002;).”
Quo vadis C4? An ecophysiological perspective on global change and the future of C4 plants (2004, background): “In one extreme case, the C4 grass Muhlenbergia richardsonis grows in alpine tundra near 4000 m where it regularly experiences temperatures below zero during the growing season (Sage and Sage 2002).”
Climate change and ocean acidification effects on seagrasses and marine macroalgae (2013, background): “Furthermore, if photorespiration is ameliorated by high [CO2], increasing temperatures within the range of 5–40 °C are likely to elevate photosynthetic rates by increasing electron transport capacity and sucrose/starch synthesis (Sage et al., 1995; Sage, 2002; Sage & Kubien, 2007).”
A physiological analogy of the niche for projecting the potential distribution of plants (2012, background): “Laboratory studies suggest that the optimum temperature for photosynthesis across species is typically 38–45 C in C4 and 20–30 C in C3 species (Sage, 2002; Kattge & Knorr, 2007; Sage & Kubien, 2007).”
Low temperature effects on photosynthesis and growth of grapevine (2004, background): “ciency (Sage 2002), but Rubisco activation state also decreases when end-product limitation depletes the pool of inorganic phosphate and the concentration of RuBP”
Would transformation of C3 crop plants with foreign Rubisco increase productivity? A computational analysis extrapolating from kinetic properties to canopy photosynthesis (2004, background): “…algae have been reported with a significantly greater t than that of C3 crops, yet with a similar or higher kcc (Whitney et al. 2001) and C4 forms of Rubisco generally appear to have adapted to the high CO2 environment by increasing kcc at the expense of Kcm with little change in t (Sage 2002).”
Evolutionary Legacy Effects on Ecosystems: Biogeographic Origins, Plant Traits, and Implications for Management in the Era of Global Change (2016, background): “…in species originating in cool environments relative to those originating in warm environments, and CO2-binding affinities are higher in C3 plants from warm climates, indicating that RuBisCO has evolved to improve plant performance in the climatic environments in which they occur (Sage 2002).”
Temperature dependence of growth, development, and photosynthesis in maize under elevated CO2 (2007, methodology): “At higher temperatures, the CO2 saturated A is hought to be limited by RuBP regeneration rate or PEP regenration rate while CE mainly controlled by PEPC activity in 4 plants (Sage, 2002).”
