New Phytologist, Volume 247, Issue 3, Page 1244-1262, August 2025.Summary Biophysical CO2 concentrating mechanisms (CCMs) operating at the single‐cell level have evolved independently in eukaryotic algae and a single land plant lineage, hornworts. An important component for an efficient eukaryotic CCM is a pyrenoid whose biology is well‐characterized in the unicellular green alga, Chlamydomonas reinhardtii.

Improving Crop Yield through Increasing Carbon Gain and Reducing Carbon Loss
PlantsPhotosynthesis is a process where solar energy is utilized to convert atmospheric CO2 into carbohydrates, which forms the basis for plant productivity. The increasing demand for food has created a global urge to enhance yield. Earlier, the plant breeding

The Diverse AAA+ Machines that Repair Inhibited Rubisco Active Sites
Frontiers in Molecular Biosciences, 2017 Gaseous carbon dioxide enters the biosphere almost exclusively via the active site of the enzyme ribulose 1,5-bisphosphate carboxylase/oxygenase (Rubisco).

Structure, function and assembly of Rubisco activase
The FASEB Journal, 2013 In higher plants, the P‐loop ATPase Rubisco activase (Rca) helps coordinate the light and dark reactions of photosynthesis by catalyzing the release of inhibitors from Rubisco. When ATP levels drop or the temperature rises, Rca activity falls off, Rubisco inactivates, and atmospheric carbon fixation ceases.

Plant Production Science, 2005 We found that several BC2F4 lines had high leaf photosynthetic rates under light-saturated and ambient CO2 conditions. These lines are progenies of BC2F1 plants with high photosynthetic capacities which were generated by backcrossing between Oryza ...

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 ...

Thermal acclimation of photosynthetic activity and RuBisCO content in two hybrid poplar clones.
PLoS ONE, 2019 The mechanistic bases of thermal acclimation of net photosynthetic rate (An) are still difficult to discern, and the data sets available are scarce, particularly for hybrid poplar.

Frontiers in Plant Science, 2018 For modeling approaches in systems biology, knowledge of the absolute abundances of cellular proteins is essential. One way to gain this knowledge is the use of quantification concatamers (QconCATs), which are synthetic proteins consisting of proteotypic
