TL;DR: Individual leaves of potato (Solanum tuberosum L. W729R), a C(3) plant, were subjected to various irradiances, CO(2) levels, and temperatures in a controlled-environment chamber and found that water use efficiency, when considered at a constant vapor pressure gradient, increased with increasing irradiance, CO (2) concentration, and temperature.

TL;DR: The magnitude of the percentage inhibition of photosynthesis by atmospheric levels of O(2) in the C(3) species Solanum tuberosum L., Medicago sativa L., Phaseolus vulgaris L., Glycine max L., and Triticum aestivum L. increases in a similar manner with an increase in the apparent solubility ratio in the leaf.

TL;DR: The decrease in quantum yield with increasing leaf temperature in C3 species may be largely caused by a temperaturedependent change in the solubility ratio of O2/CO2.

TL;DR: A model for separating O(2) inhibition of photosynthesis into two components, direct competitive inhibition and inhibition due to photorespiration, was presented from both simulated and experimental data of photosynthetic response curves to varying CO(2), with results showing the photorespiratory part of O(1) inhibition is considered as a major component at Gamma and increases with increasing temperature and with increase in O( 2)/CO(2).

TL;DR: The intracellular locations of six key enzymes of Crassulacean acid metabolism were determined using enzymically isolated mesophyll protoplasts of Sedum praealtum D.C. using isopycnic sucrose density gradient centrifugation to establish the chloroplastic location of pyruvate Pi dikinase, the mitochondrial location of NAD-linked malic enzyme, and exclusively nonparticulate locations of phosphoenolpyruvating enzymes.
