Heat stress induced cytosine methylation in the coding region of Rubisco activase (Rca) reveals its genotype-specific expression in contrasting wheat genotypes

Indian Journal of Genetics and Plant Breeding (The)
Rising environmental temperature has become a major concern in global wheat production since it has critical effects on plant growth,development and yield. Elevated temperatures have become.

Advances in gene cloning and functional genomics approaches for wheat (Triticum aestivum L.) improvement

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Wheat (Triticum aestivum L.) is a globally important cereal crop which provides ∼20% calories in human diet. Identifying genes and elucidating their functions is still challenging in wheat due to its large genome (∼16 Gb) with significant amount of repetitive elements.

Improving drought-, salinity-, and heat-tolerance in transgenic plants by co-overexpressing Arabidopsis vacuolar pyrophosphatase gene AVP1 and Larrea Rubisco activase gene RCA.

Plant Science, 2020
The severity and frequency of many abiotic stresses such as drought, salinity and heat, cause substantial crop losses worldwide, which poses a serious challenge in food security. To increase crop production, new approaches are needed.

Gold Immunolocalization of Rubisco and Rubisco Activase in Pyrenoid of Chlamydomonas reinhardtii

ALGAE, 2003
The pyrenoid ultrastructure and distribution of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and Rubisco activase in the chloroplasts of Chlamydomonas reinhardtii was studied using the immunogold localization technology with electron microscopy. There were several tubular thylakoids invading in the pyrenoid matrix to form several spokewise

Rubisco Activases: AAA+ Chaperones Adapted to Enzyme Repair [PDF]

Frontiers in Molecular Biosciences, 2017
Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), the key enzyme of the Calvin-Benson-Bassham cycle of photosynthesis, requires conformational repair by Rubisco activase for efficient function. Rubisco mediates the fixation of atmospheric CO2 by catalyzing the carboxylation of the five-carbon sugar ribulose-1,5-bisphosphate (RuBP).

Shaping future forests: how can ecophysiology support climate‐smart forest management?

New Phytologist, Volume 250, Issue 5, Page 2778-2813, June 2026.
Summary Climate change, particularly the associated increase in extreme events and disturbances, threatens the numerous environmental, social, and economic benefits that forests provide, both locally and globally. Heat and drought pose significant risks to forest ecosystems; the anticipated future climate is expected to exacerbate this trend ...

Immunolocalization of Rubisco Activase and Rubisco in C3 and C4 Plant Tissues

Microscopy and Microanalysis, 2000
Abstract Ribulose bisphosphate carboxylase/oxygenase (Rubisco), an abundant enzyme in chloroplasts, must be activated by CO2 in order for it to catalyze the carboxylation of ribulose bisphosphate. Rubisco activase, a nuclear encoded chloroplast protein was first identified as a biochemical lesion in the rca mutant of Arabidopsis (1 ...

Identification and characterization of multiple rubisco activases in chemoautotrophic bacteria [PDF]

Nature Communications, 2015
AbstractRibulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) is responsible for almost all biological CO2 assimilation, but forms inhibited complexes with its substrate ribulose-1,5-bisphosphate (RuBP) and other sugar phosphates. The distantly related AAA+ proteins rubisco activase and CbbX remodel inhibited rubisco complexes to effect inhibitor ...

Mechanical Strength: An Unrecognised Target in the Genetic Improvement of Crops

Plant Biotechnology Journal, Volume 24, Issue 6, Page 4190-4203, June 2026.
ABSTRACT Leaf angle (LA) is a crucial agronomic trait influencing planting density and crop yield. Previous research highlighted the importance of cellular variations in the ligular region for determining LA, but the underlying regulatory mechanisms remain unclear.

Effects of CO2, light and temperature on rubisco activase protein in wheat leaf segments

, 1998
Rubisco activase catalyzes the ATP-dependent activation of rubisco. At moderately elevated temperature (for wheat above 30°C), rubisco activase becomes reversibly inactivated in leaf segments (2). A further increase of the temperature (for wheat above
