The rates of respiration in light and darkness, Ci/Ca and carbon isotope fractionation were investigated in glycine decarboxylase-deficient plants of barley, potato and Arabidopsis thaliana grown in climate chambers with controlled light intensity, temperature, humidity, irradiation and different CO2 concentrations (360, 700 and 1400 µl l−1) and compared to the wild-type plants. All photorespiration-impaired plants exhibited higher Ci/Ca and corresponding lower apparent water-use efficiencies… Expand

Acclimation of C4 metabolism to low light in mature maize leaves could limit energetic losses during progressive shading in a crop canopy
TLDR
Maize plants were grown under light regimes representing the cycle that leaves undergo in the canopy, whereby younger leaves initially developed under high light and were then re-acclimated to low light for 3 weeks, showing that irrespective of whether leaves are acclimated to very low or high light intensity, the biochemical efficiency of the C4 cycle does not decrease at low photosynthetically active radiation.

The Role of Phosphoenolpyruvate Carboxylase during C4 Photosynthetic Isotope Exchange and Stomatal Conductance1[OA]
TLDR
It is concluded that in vitro carbonic anhydrase activity overestimated θ as compared to values determined from Δ18O in wild-type plants. Expand
Improvement of photosynthesis in rice (Oryza sativa L.) as a result of an increase in stomatal aperture and density by exogenous hydrogen sulfide treatment
Hydrogen sulfide (H2S) is considered to be the third gaseous signaling molecule after NO and CO, and it plays an active role in regulating the physiological processes of plants and animals. In thisExpand
Faster Removal of 2-Phosphoglycolate through Photorespiration Improves Abiotic Stress Tolerance of Arabidopsis
TLDR
The previous hypothesis that a faster photorespiratory metabolism improves tolerance against unfavorable environmental conditions, such as high light intensity and temperature as well as drought, is strengthened. Expand
Acclimation to low light by C4 maize: implications for bundle sheath leakiness.
TLDR
This work explains the pattern by two contrasting acclimation strategies: HL plants maintained a high CCM activity at LL, resulting in high CO2 overcycling and increased Φ; LL plants acclimated by down-regulating the CCM, effectively optimizing scarce ATP supply. Expand
Carbon Isotope Fractionation during Photorespiration and Carboxylation in Senecio1[W][OA]
TLDR
The results emphasize that the effects of photorespiration must be taken into account when partitioning net CO2 exchange of ecosystems into gross fluxes of photosynthesis and respiration. Expand
Near isohydric grapevine cultivar displays higher photosynthetic efficiency and photorespiration rates under drought stress as compared with near anisohydric grapevine cultivar.
TLDR
Compared to Shiraz, the reduced stomata conductance values of Cs were accompanied by higher water use efficiency and photorespiration rates, as well as photosystem II photochemical potential, which was observed in the stability of Fv /Fm under drought stress. Expand
Differences in instantaneous water use efficiency derived from post-carboxylation fractionation respond to the interaction of CO 2 concentrations and water stress in semi-arid areas
In the context of global warming attributable to the increasing levels of CO 2 , severe drought can be anticipated in areas with chronic water shortages (semi-arid areas), which necessitates researchExpand
Variation of carbon and isotope natural abundances (δ15N and δ13C) of whole-plant sweet potato (Ipomoea batatas L.) subjected to prolonged water stress.
TLDR
The δ15N values indicated a generalised N reallocation between whole-plant organs under drought, as a physiological integrator of response to environmental stress, which can aid the selection of traits to be used in sweet potato breeding programs, to adapt this crop to climate change. Expand
Temperature response of carbon isotope discrimination and mesophyll conductance in tobacco.
TLDR
The increase in gm with increasing leaf temperature resulted in the drawdown in CO2 partial pressure between intercellular airspaces and the sites of carboxylation decreasing substantially at high temperature, nearly independent of leaf temperature. Expand

The role of photorespiration during drought stress : an analysis utilizing barley mutants with reduced activities of photorespiratory enzymes
TLDR
It is demonstrated that photorespiration was enhanced during drought stress in barley and that the control exerted by photorespiratory enzymes on the rate of photosynthetic electron transport and CO2 fixation was increased. Expand

TLDR
It is concluded that photorespiration serves as an effective redox transfer mechanism from the chloroplast in plants with a lowered GDC content, which leads to over-reduction and over-energization of the chloroplasts. Expand

The measurement of δ13C in the leaves of the GDC-deficient barley (Hordeum vulgare L.) mutant (LaPr 87/30) plants indicated that photorespiratory carbon isotope fractionation takes place in vivo. Expand

TLDR
The observed discrimination during dark respiration, releasing 13 C-enriched CO 2 , may partly explain the higher fractionation in the remaining leaf organic matter compared to the overall discrimination during photosynthesis, as measured on-line. Expand

TLDR
It is concluded that in the absence of stress, elevated CO 2 slightly affects leaf conductance in A. thaliana and there is a strong interaction in stomatal responses to CO 2 and ABA which is not modified by growth at elevatedCO 2. Expand
