Unraveling Field Crops Sensitivity to Heat Stress：Mechanisms, Approaches, and Future Prospects (2018, background): “However, some researchers reported slight or no harm to photosystem II due to moderate thermal stress [88].”
Extreme climatic events: impacts of drought and high temperature on physiological processes in agronomically important plants (2014, background): “Photosynthesis and plant productivity can be reversibly or irreversibly affected by extreme environmental conditions such as drought or heat (Haldimann and Feller, 2005; Sharkey, 2005; Signarbieux and Feller, 2012).”
The emission factor of volatile isoprenoids: stress, acclimation, and developmental responses (2010, background): “Standard physiological measures such as photosynthesis rate and stomatal conductance can provide important clues of the presence of environmental and biotic stresses, especially if baseline estimates of leaf physiological activity in non-stressed plants (e.g., Flexas and Medrano, 2002; Sharkey, 2005”
Abiotic stresses, constraints and improvement strategies in chickpea (2014, background): “Temperature beyond 40°C causes disruption in photo system I and II (Baker 1991, Sharkey 2005) and also affects respiration (Kurets and Popov 1988), membrane composition and its stability (Levitt 1969), nitrogen fixation (Black et al. 1978) and water relation (McDonald and Paulsen 1997).”
High thermal acclimation potential of both photosynthesis and respiration in two lowland Plantago species in contrast to an alpine congeneric (2006, background): “Temperatures above those normally encountered by plants in their natural environment may cause reduced photosynthetic rates because of inactivation of Rubisco (Salvucci & Crafts-Brandner, 2004) and leakiness of photosynthetic membranes (Sharkey, 2005).”
Photosynthesis under stressful environments: An overview (2013, background): “However, there are some reports showing that moderately high temperature (35–45°C) can induce the cyclic transport of electrons and thylakoid membranes become leaky (Sharkey 2005).”
Photosynthetic Response of Plants Under Different Abiotic Stresses: A Review (2019, background): “Elevated temperature alters PS I activities by increasing cyclic electron flow around PS I and altering thylakoid proton conductance (Bukhov and Carpentier 2000; Sharkey 2005), thus suggesting more heat stability in PS I than PS II.”
Heat Stress in Wheat during Reproductive and Grain-Filling Phases (2011, background): “Through effects on photosystem II (PSII)- and photosystem I (PSI)-mediated electron transfer, and Calvin cycle activity, exposure to heat stress (40◦C) damages the photosynthetic apparatus (Baker, 1991; Sharkey, 2005).”
