Cyanobacterial carboxysomes contain an unique rubisco‐activase‐like protein [PDF]

New Phytologist, 2019
Summary In plants, rubisco activase (Rca) regulates rubisco by removing inhibitory molecules such as ribulose‐1,5‐bisphosphate (RuBP). In cyanobacteria, a homologous protein (activase‐like cyanobacterial protein, ALC), contains a distinctive C‐terminal fusion resembling the small‐subunit of rubisco.

Toward the application of artificial intelligence (AI) proteomics in the agriculture

Crop Science, Volume 65, Issue 6, November/December 2025.
Abstract Proteomics enables the comprehensive analysis of proteins that drive cells and is thus the ultimate method for profiling biological systems. However, proteomics analyses are time‐consuming and expensive, which has limited their applications to basic science and advanced medical research.

Changes in PEP Carboxylase, Rubisco and Rubisco activase mRNA levels from maize (Zea mays) exposed to a chronic ozone stress

Biological Research, 2007
We quantified the ozone impact on levels of Zea mays L. cv. Chambord mRNAs encoding C4-phosphoenolpyruvate carboxylase (C4-PEPc), ribulose-l,5-bisphosphate carboxylase/oxygenase small and large subunits (Rubisco-SSU and Rubisco-LSU, respectively) and ...

Heat Denaturation Profiles of Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase (Rubisco) and Rubisco Activase and the Inability of Rubisco Activase to Restore Activity of Heat-Denatured Rubisco

Plant Physiology, 1997
Abstract We compared the heat-denaturation profiles of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase and further examined the ability of Rubisco activase to restore the activity of heat-denatured Rubisco originally reported (E. Sanchez de Jimenez, L. Medrano, and E. Martinez-Barajas [1995] Biochemistry 34:

Expression level of Rubisco activase negatively correlates with Rubisco content in transgenic rice [PDF]

Photosynthesis Research, 2018
The relationship between ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase (Rca) levels was studied using transgenic rice overexpressing maize Rca (OX-mRca) and knockdown transgenic rice expressing antisense Rca (KD-Rca).

Environmental factors have a greater influence on photosynthetic capacity in C4 plants than biochemical subtypes or growth forms

New Phytologist, Volume 248, Issue 3, Page 1205-1224, November 2025.
Summary Our understanding of how photosynthetic capacity varies among C4 species and across growth and measurement conditions remains limited. We collated 1696 CO2 response curves of net CO2 assimilation rate (A/Ci curves) from C4 species grown and measured at various environmental conditions and used these data to estimate the apparent maximum ...

Activation of interspecies-hybrid Rubisco enzymes to assess different models for the Rubisco–Rubisco activase interaction

Photosynthesis Research, 2013
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) is prone to inactivation from non-productive binding of sugar-phosphates. Reactivation of Rubisco requires conformational remodeling by a specific chaperone, Rubisco activase. Rubisco activase from tobacco and other plants in the family Solanaceae is an inefficient activator of Rubisco from non ...

Electronic Nanomaterials for Plants: A Review on Current Advances and Future Prospects

Advanced Electronic Materials, Volume 11, Issue 17, October 20, 2025.
Global food security faces mounting challenges from climate change and rapid population growth. This review highlights the pivotal role of electronic nanomaterials–including metals, metal oxides, and carbon‐based structures–in enhancing plant photosynthesis, nutrient uptake, and stress resilience. Furthermore, it explores how emerging platforms such as

Molecular adaptation during adaptive radiation in the Hawaiian endemic genus Schiedea.

PLoS ONE, 2006
Background"Explosive" adaptive radiations on islands remain one of the most puzzling evolutionary phenomena. The rate of phenotypic and ecological adaptations is extremely fast during such events, suggesting that many genes may be under fairly strong ...

The discovery of Rubisco activase — yet another story of serendipity [PDF]

Photosynthesis Research, 2002
A brief history of Rubisco (ribulose bisphosphate carboxylase oxygenase) research and the events leading to the discovery and initial characterization of Rubisco activase are described. Key to the discovery was the chance isolation of a novel Arabidopsis photosynthesis mutant.
