Identification of putative RuBisCo activase (TaRca1) ˗ the catalytic chaperone regulating carbon assimilatory pathway in wheat (Triticum aestivum) under the heat stress [PDF]
Frontiers in Plant Science, 2016 RuBisCo activase (Rca) is a catalytic chaperone involved in modulating the activity of RuBisCo (key enzyme of photosynthetic pathway). Here, we identified eight novel transcripts from wheat through data mining predicted to be Rca and cloned a transcript ...

Silicon Modulates the Chloroplast Proteome to Enhance Drought Tolerance in Soybean [PDF]
PlantsSoybeans are highly susceptible to drought stress, which significantly impairs their growth and yield. Silicon (Si) supplementation has emerged as a promising strategy to mitigate drought-induced damage in plants.

Photosynthesis-related genetic and transcriptomic variations contribute to adaptive trait diversity in global Arabidopsis thaliana populations [PDF]
BMC Plant BiologyPhotosynthesis is the foundational process for carbon fixation in terrestrial ecosystems. Although allelic variations in photosynthesis-related genes have the potential to enhance carbon assimilation efficiency, their functional roles in local adaptation

Rubisco, Rubisco activase, and global climate change [PDF]
Journal of Experimental Botany, 2008 Global warming and the rise in atmospheric CO(2) will increase the operating temperature of leaves in coming decades, often well above the thermal optimum for photosynthesis. Presently, there is controversy over the limiting processes controlling photosynthesis at elevated temperature.

Effects of OsRCA Overexpression on Rubisco Activation State and Photosynthesis in Maize
Plants, 2023 Ribulose–1,5–bisphosphate carboxylase/oxygenase (Rubisco) is the rate–limiting enzyme for photosynthesis. Rubisco activase (RCA) can regulate the Rubisco activation state, influencing Rubisco activity and photosynthetic rate. We obtained transgenic maize

Regulation of Rubisco activase and its interaction with Rubisco [PDF]
Journal of Experimental Botany, 2007 The large, alpha-isoform of Rubisco activase confers redox regulation of the ATP/ADP response of the ATP hydrolysis and Rubisco activation activities of the multimeric activase holoenzyme complex. The alpha-isoform has a C-terminal extension that contains the redox-sensitive cysteine residues and is characterized by a high content of acidic residues ...

The Catalytic Role of RuBisCO for in situ CO2 Recycling in Escherichia coli
Frontiers in Bioengineering and Biotechnology, 2020 Ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO) is a key enzyme responsible for biological CO2 assimilation. RuBisCO can be heterologously expressed in Escherichia coli so that glucose and CO2 are co-metabolized to achieve high mixotrophic ...

An ancient metabolite damage-repair system sustains photosynthesis in plants
Nature Communications, 2023 Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is the major catalyst in the conversion of carbon dioxide into organic compounds in photosynthetic organisms. However, its activity is impaired by binding of inhibitory sugars such as xylulose-1,5-
