Journal ArticleDOI
The Costs of Photorespiration to Food Production Now and in the Future
Berkley J. Walker,Berkley J. Walker,Andy VanLoocke,Carl J. Bernacchi,Carl J. Bernacchi,Donald R. Ort,Donald R. Ort +6 more
TL;DR: The benefit of improving its efficiency appears to outweigh any potential secondary disadvantages, and models suggest a 12-55% improvement in gross photosynthesis in the absence of photorespiration, even under climate change scenarios predicting the largest increases in atmospheric carbon dioxide concentration.
Journal ArticleDOI
The Impacts of Fluctuating Light on Crop Performance.
Rebecca A. Slattery,Rebecca A. Slattery,Berkley J. Walker,Andreas P.M. Weber,Donald R. Ort,Donald R. Ort +5 more
TL;DR: The current understanding of the underlying mechanisms of these limitations to photosynthesis in fluctuating light that have shown promise in improving the response times of photosynthesis-related processes to changes in light intensity are reviewed.
Journal ArticleDOI
Temperature response of in vivo Rubisco kinetics and mesophyll conductance in Arabidopsis thaliana: comparisons to Nicotiana tabacum.
TL;DR: While the individual Rubisco kinetic parameters in N. tabacum and A. thaliana were similar across temperatures, they collectively resulted in significantly different modelled rates of photosynthesis, highlighting the importance of considering species-dependent differences in Rubisco kinetics and gm when modelling the temperature response of Photosynthesis.
Journal ArticleDOI
Manipulating photorespiration to increase plant productivity:recent advances and perspectives for crop improvement
Marco Betti,Hermann Bauwe,Florian A. Busch,Alisdair R. Fernie,Olivier Keech,Myles Levey,Donald R. Ort,Martin A. J. Parry,Rowan F. Sage,Stefan Timm,Berkley J. Walker,Andreas P.M. Weber +11 more
TL;DR: Recent advances obtained in photorespiratory engineering are summarized and prospects for these advances to be transferred to major crops to help address the globally increasing demand for food and biomass production are discussed.
Journal ArticleDOI
The Response of Cyclic Electron Flow around Photosystem I to Changes in Photorespiration and Nitrate Assimilation
TL;DR: It is suggested that other mechanisms, such as the malate valve and the Mehler reaction, were able to maintain energy balance when electron flow was low but that CEF was required under higher flow, and responded to energy demand under high light but not low light.
