A characterisation of Rubisco activase from Spinacia oleracea [PDF]
, 2014 Rubisco activase undergoes ATP hydrolysis to activate Rubisco which has generated an inhibitor. Recent crystallographic evidence has proposed several models however the correct model is disputed.

Heat-induced changes in the abundance of wheat Rubisco activase isoforms.
New Phytologist, 2020 The Triticum aestivum (wheat) genome encodes three isoforms of Rubisco activase (Rca) differing in thermostability, which could be exploited to improve the resilience of this crop to global warming.

Coordinate Expression of Rubisco Activase and Rubisco during Barley Leaf Cell Development [PDF]
Plant Physiology, 1989 We have utilized the cellular differentiation gradient and photomorphogenic responses of the first leaf of 7-day-old barley (Hordeum vulgare L.) to examine the accumulation of mRNA and protein encoded by the ribulose-1,5-biphosphate carboxylase holoenzyme (rubisco) activase gene (rca).

Plant, Cell &Environment, EarlyView.ABSTRACT Climate change‐driven heat and drought stresses during reproductive stages significantly threaten wheat productivity. To investigate the genetic and physiological basis of combined heat–drought (HD) tolerance, we evaluated 345 wheat genotypes under three environments of HD stresses, non‐stress glasshouse conditions and a late‐sowing field ...

Effects of the Terminal Regions on Rubisco Activase Form and Function [PDF]
, 2017 Rubisco is the sole enzyme responsible for the incorporation of CO2 into sugar molecules useable by all life on earth. In the vast majority of discovered autotrophic organisms their respective rubisco has been accompanied by another enzyme called ...

Plant, Cell &Environment, EarlyView.ABSTRACT We studied near‐instantaneous temperature responses of light‐saturated photosynthesis (Asat) and the operating efficiency of photosystem II (ΦPSII) in relation to acclimation of photosynthetic biochemistry to temperature at the timescale of 1–8 days. We grew two closely related Brassica oleracea L.

Reductions of Rubisco Activase by Antisense RNA in the C4 Plant Flaveria bidentis Reduces Rubisco Carbamylation and Leaf Photosysthesis [PDF]
, 2015 To function, the catalytic sites of Rubisco (EC 4.1.1.39) need to be activated by the reversible carbamylation of a lysine residue within the sites followed by rapid binding of magnesium.

Purification and Assay of Rubisco Activase from Leaves
Plant Physiology, 1988 Ribulose 1,5-bisphosphate carboxylase/oxygenase (rubisco) activase protein was purified from spinach leaves by ammonium sulfate precipitation and ion exchange fast protein liquid chromatography. This resulted in 48-fold purification with 70% recovery of activity and yielded up to 18 milligrams of rubisco activase protein from 100 grams of leaves. Based

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.Abstract China's forests have experienced a notable increase in leaf area, driven by planted forest expansion and natural forest conservation. However, how planted and natural forests respond differently to environmental changes remains unclear. Using leaf area index (LAI) data, propensity score matching (PSM), and machine learning, we compared these ...

Evolutionary escape from the Rubisco activase requirement
, 2019 Ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco) catalyzes the rate-limiting carbon fixation step in photosynthesis. Despite its essential role, Rubisco is inefficient and possesses sluggish kinetics.
