Abstract: Recycling of the 2-phosphoglycolate generated by the oxygenase reaction of Rubisco requires a complex and energy-consuming set of reactions collectively known as the photorespiratory cycle. Several approaches aimed at reducing the rates of photorespiratory energy or carbon loss have been proposed, based either on screening for natural variation or by means of genetic engineering. Recent work indicates that plant yield can be substantially improved by the alteration of photorespiratory fluxes or by engineering … Show more

“…The current available options to achieve these goals include: (1) direct manipulation of Rubisco through chloroplast transformation, (2) incorporation of a CCM that includes either a Kranz-type C 4 photosynthetic pathway or the bacterial carboxysome to reduce the competitive inhibition of Rubisco by O 2 (allowing the maximal rate of carboxylation to be achieved; Fig. S1) and (3) providing a photorespiratory bypass (Betti et al, 2016). Using knowledge we have gained from Rubisco engineering within tobacco chloroplasts, a next-generation plastid transformation construct design will need to incorporate the genes that are vital for Rubisco synthesis and assembly and maintaining New Phytologist (2017)…”

“…Therefore, genetic engineering of the native photorespiratory pathway, in combination with anatomical modifications to increase recovery of photorespired CO 2 and manipulation of other areas of metabolism closely associated with photorespiration, could be important strategies when developing crops able to sustain increased yields to meet the predicted future food demands (Betti et al ; Timm et al ; Lopez‐Calcagno et al ).…”

“…While there is not always a strong link between photosynthetic CO 2 uptake and improved crop yield, in general it seems to be beneficial to increase A to obtain a higher plant biomass (Long et al, 2006). Many strategies to increase A have been proposed, from altering Rubisco kinetic properties to reduce photorespiration, over improving the thermotolerance of Rubisco activase, the CO 2 diffusion into the chloroplast, and boosting photosynthetic light-use efficiency, to enhancing the capacity of carbon utilization (discussed, e.g., in Ort et al, 2011;Betti et al, 2016;Yamori et al, 2016). Many of these approaches will work better under some environmental conditions than others, and our results will help to narrow down strategies that will be successful.…”
