Molecular mechanism of Rubisco activase: Dynamic assembly and Rubisco remodeling [PDF]
Frontiers in Molecular Biosciences, 2023 Ribulose-1,5-bisphosphate (RuBP) carboxylase-oxygenase (Rubisco) enzyme is the limiting step of photosynthetic carbon fixation, and its activation is regulated by its co-evolved chaperone, Rubisco activase (Rca). Rca removes the intrinsic sugar phosphate

Overexpression of Rubisco Activase Improves Photosynthesis and Plant Growth in Rice Under Fluctuating Light Under Future High CO<sub>2</sub> Conditions. [PDF]
Plant Cell EnvironABSTRACT Rubisco activase mediates the activation of Rubisco, the key photosynthetic CO2‐fixing enzyme, and plays a crucial role in regulating photosynthesis and plant growth. Rubisco activase restores catalytic competence to Rubisco active sites by promoting the release of inhibitors in an ATP‐dependent manner.

Partitioning of Rubisco activase into the pyrenoidal Rubisco condensate is mediated by a functional protein-protein interaction [PDF]
Nature CommunicationsMost unicellular microalgae achieve robust photosynthetic CO2-fixation by sequestering their carboxylase in chloroplastic Rubisco condensates (Rubiscondensates) termed pyrenoids.

Photosynthetic Responses to Rising CO<sub>2</sub> and Temperature: Mechanisms, Models, and Field Evidence. [PDF]
Glob Chang BiolThis review revisits the mechanistic basis of CO2 × temperature interactions in C3 photosynthesis and evaluates how subsequent research has refined this framework. We synthesize evidence showing how acclimation, diffusive limitations, and canopy processes modify photosynthetic responses to rising CO2 and warming across scales.

Genetic determinants controlling maize rubisco activase gene expression and a comparison with rice counterparts [PDF]
BMC Plant Biology, 2019 Background Rubisco activase (RCA) regulates the activity of Rubisco and is a key enzyme of photosynthesis. RCA expression was widely reported to affect plant photosynthesis and crop yield, but the molecular basis of natural variation in RCA expression in

Down‐regulation of wheat Rubisco activase isoforms expression by virus‐induced gene silencing [PDF]
Plant DirectRubisco activase (Rca) is an essential photosynthetic enzyme that removes inhibitors from the catalytic sites of the carboxylating enzyme Rubisco. In wheat, Rca is composed of one longer 46 kDa α‐isoform and two shorter 42 kDa β‐isoforms encoded by the ...

Identification of two bZIP transcription factors interacting with the promoter of soybean Rubisco activase gene (GmRCAα) [PDF]
Frontiers in Plant Science, 2016 Rubisco activase (RCA), a key photosynthetic protein, catalyses the activation of Rubisco and thus plays an important role in photosynthesis. Although the RCA gene has been characterized in a variety of species, the molecular mechanism regulating its ...

Drought priming promotes phloem loading-driven sucrose export to alleviate the photosynthetic limitations under low nitrogen stress in wheat seedlings [PDF]
Frontiers in Plant ScienceReducing nitrogen (N) application can improve nitrogen use efficiency (NUE) and mitigate environmental pollution. However, this reduction often adversely affects photosynthesis and leads to inhibition of wheat growth.
