Effects of 2,4-epibrassinolide on photosynthesis and Rubisco activase gene expression in Triticum aestivum L. seedlings under a combination of drought and heat stress (2016, background): “As the primary limiting factor of net photosynthesis (Salvucci and Crafts-Brandner 2004; Wang et al. 2015), the activation state of Rubisco (ribulose-1,5-bispho- sphate carboxylase/oxygenase) is regulated by Rubisco activase (RCA) via the maintenance of Rubisco catalytic sites in the active state…”
Research Advances in Mechanisms of Turfgrass Tolerance to Abiotic Stresses: From Physiology to Molecular Biology (2014, background): “Although the catalytic activity of Rubisco increases with temperature, the low affinity of the enzyme for CO2 and its dual nature as an oxygenase at high temperature limit the possible rise in C3 net photosynthetic rate (Salvucci and Crafts-Brandner, 2004).”
Effect of varying high temperatures during reproductive growth on reproductive function, oxidative stress and seed yield in chickpea genotypes differing in heat sensitivity (2013, result): “The cellular oxidizing ability was reduced appreciably at 45/35°C suggesting impairment in respiration and energy generation, possibly due to inactivation of the enzymes (Salvucci and Crafts-Brandner 2004 ), which match with previous studies on heat stress in potato (Coria et al.”
Decreased CO2 availability and inactivation of Rubisco limit photosynthesis in cotton plants under heat and drought stress in the field (2012, background): “In addition, many studies have linked the inhibition of A at elevated temperatures to a decrease in Rubisco activation, caused by the exceptional thermal lability of Rubisco activase (Feller et al., 1998; Crafts-Brandner and Salvucci, 2000; Salvucci and Crafts-Brandner, 2004a,b).”
Heat Stress in Wheat during Reproductive and Grain-Filling Phases (2011, background): “Although Rubisco catalytic activity increases with temperature, its low affinity for CO2 and ability to act as an oxygenase limit the chance of increasing net photosynthesis with temperature (Salvucci and Crafts-Brandner, 2004a).”
