  Growth in fluctuating light buffers plants against photorespiratory perturbations

  The detoxification pathway photorespiration has been thought to be photoprotective in dynamic light. The authors report that, instead, growth in dynamic light buffers plants against photorespiratory lesions by reducing photosynthesis and inducing metabolite re-routing.

  Boreal conifers maintain carbon uptake with warming despite failure to track optimal temperatures

  Acclimation of tree photosynthesis to warming may be affected by elevated CO₂. Here, the authors show that mature boreal conifers may be able to maintain leaf-level C uptake under warming and elevated CO₂ even if optimum temperature of photosynthesis does not track increased temperature.

  Rubisco deactivation and chloroplast electron transport rates co-limit photosynthesis above optimal leaf temperature in terrestrial plants

  Photosynthesis declines at mild temperatures in terrestrial plants. Here, the authors use published data to show that decline in photosynthetic CO₂ assimilation rate with rising temperatures can be accounted for by Rubisco deactivation and declines in chloroplast electron transport rate.

  In planta study of photosynthesis and photorespiration using NADPH and NADH/NAD⁺ fluorescent protein sensors

  NADP(H) and NAD(H) are crucial energy molecules in plant metabolism. Here, via the use of circularly permutated fluorescent protein sensors, the authors demonstrate dynamic changes in NADPH and the NADH/NAD⁺ ratio during photosynthesis and photorespiration at the subcellular level in planta.

  Augmenting the Calvin–Benson–Bassham cycle by a synthetic malyl-CoA-glycerate carbon fixation pathway

  Improving carbon fixation efficiency and reducing carbon loss have been long term goals for people working on photosynthetic organism improvement. Here, the authors design a synthetic malyl-CoA-glycerate pathway for efficient acetyl-CoA synthesis and verify its function in vitro, in E. coli and in cyanobacterium.

  Greater efficiency of photosynthetic carbon fixation due to single amino-acid substitution

  Phosphoenolpyruvate carboxylase, the key enzyme of C4 photosynthesis, evolved from an ancestral isoform in C3 plants and has a reduced feedback inhibition. Paulus et al.show that enhanced inhibitor tolerance of C4 phosphoenolpyruvate carboxylase is achieved by a single amino-acid exchange.
