However, such an increase in the photosynthetic efficiency will depend on the environmental conditions and on the responsiveness of Rubisco to temperature and CO2 availability. After an exhaustive compilation and standardization of the data published so far, a large natural variability in the thermal responses of Rubisco kinetic parameters in higher plant species was revealed. The variability observed was related to the photosynthetic type but a limited adaptation to the species thermal environment was found. We provide theoretical evidence that the existence of distinctive Rubisco responses to varying temperature and CO2 concentration constitutes a promising avenue for increasing the photosynthetic capacity of important crops under future climatic conditions.", "keywords": ["Crops", " Agricultural", "0301 basic medicine", "2.

In situ gas exchange and chlorophyll fluorescence were measured after 2 months of treatments. Net photosynthetic rate (A(n)) of seedlings grown under the intermediate and high moisture regimes increased from low to intermediate T(soil) and then decreased to high T(soil). There were no significant differences between the low and high T(soil), with the exception that A(n) was significantly higher under high than low T(soil) at the high moisture regime. No significant T(soil) effect on A(n) was observed at the low moisture regime. The intermediate T(soil) increased stomatal conductance (g(s)) only at intermediate and high but not at low moisture regime, whereas there were no significant differences between the low and high T(soil) treatments. Furthermore, the difference in g(s) between the intermediate and high T(soil) at high moisture regime was not statistically significant. The low moisture regime significantly reduced the internal to ambient CO2 concentration ratio at all T(soil). There were no significant individual or interactive effects of treatment on maximum carboxylation rate of Rubisco, light-saturated electron transport rate, triose phosphate utilization or potential photochemical efficiency of photosystem II. The results of this study suggest that soil moisture condition should be taken into account when predicting the responses of white birch to soil warming.", "keywords": ["0106 biological sciences", "0301 basic medicine", "Ribulose-Bisphosphate Carboxylase", "Temperature", "Water", "Carbon Dioxide", "15.

Associated with month\uffe2\uff80\uff90to\uffe2\uff80\uff90month changes in temperature were concomitant changes in R in the light (Rlight) and darkness (Rdark), with both processes being more temperature dependent in well\uffe2\uff80\uff90watered trees than under drought. Overall rates of Rlight and Rdark were not significantly affected by [CO2]. By contrast, overall rates of Rdark (averaged across both [CO2]) were ca. 25% lower under drought than in well\uffe2\uff80\uff90watered trees. During summer, the degree of light inhibition of leaf R was greater in droughted (ca. 80% inhibition) than well\uffe2\uff80\uff90watered trees (ca. 50% inhibition). Notwithstanding these treatment differences, an overall positive relationship was observed between Rlight and Rdark when data from all months/treatments were combined (R2\uffe2\uff80\uff83=\uffe2\uff80\uff830.8). Variations in Rlight were also positively correlated with rates of Rubisco activity and nitrogen concentration. Light inhibition resulted in a marked decrease in the proportion of light\uffe2\uff80\uff90saturated photosynthesis respired (i.e. reduced R/Asat). Collectively, these results highlight the need to account for light inhibition when assessing impacts of global change drivers on the carbon economy of tree canopies.</p>", "keywords": ["0301 basic medicine", "0106 biological sciences", "Light", "01 natural sciences", "nitrogen", "ribulosebisphosphate carboxylase", "Trees", "Keywords: carbon", "leaf respiration", "Photosynthesis", "Eucalyptus", "concentration (composition)", "droughts", "drought stress", "Photorespiration", "Temperature", "Rlight", "Darkness", "Photochemical Processes", "6.

The experiment was conducted on two natural forest soils with similar texture but different pH (acidic and calcareous soils). The physiological (photosynthesis) and biochemical (antioxidant system) responses of Q.\uffc2\uffa0pubescens were investigated. On acidic soil, Q.\uffc2\uffa0pubescens had a higher reactive oxygen species (ROS) content than on calcareous soil, confirming that this species is better adapted to the latter soil type. A down\uffe2\uff80\uff90regulation of ascorbate\uffe2\uff80\uff90glutathione cycle enzymes suggests that ROS were used as signalling molecules. Air warming stimulated stomatal opening, while soil drought induced stomatal closure in the late afternoon and reduced Rubisco carboxylation efficiency. Photosynthetic performance in the combined treatment was higher than under single drought stress and similar to control and air warming. Q.\uffc2\uffa0pubescens biochemical responses depended on soil pH. On acidic soil, Q.\uffc2\uffa0pubescens trees exposed to air warming used ROS as signalling molecules. On calcareous soil, these trees were able to balance both soil drought and air warming stress, avoiding ROS toxic effects by increasing antioxidant enzyme activitiy and maintaining a high enzymatic antioxidant defence. When combined, drought and air warming induced either more severe (higher oxidative pressure and impairment of the light\uffe2\uff80\uff90harvesting complex) or different responses (decline of the thermal energy dissipation capacity) relative to the single stressors. Overall, however, Q.\uffc2\uffa0pubescens preserved the functionality of the photosynthetic apparatus and controlled the antioxidant system response, thus confirming its drought and thermo\uffe2\uff80\uff90tolerance and therefore its potential to adapt to the ongoing climate change.</p>", "keywords": ["0106 biological sciences", "0301 basic medicine", "Hot Temperature", "Climate", "Ribulose-Bisphosphate Carboxylase", "Light-Harvesting Protein Complexes", "Down-Regulation", "Global Warming", "01 natural sciences", "Antioxidants", "Quercus", "Soil", "03 medical and health sciences", "Antioxidant enzyme; ascorbate-glutathione cycle; chlorophyll a fluorescence; gas exchange; oak", "Stress", " Physiological", "Photosynthesis", "Ecosystem", "Antioxidant enzyme; ascorbate-glutathione cycle; chlorophyll a fluorescence; gas exchange; oak.", "Air", "Water", "15.
