Regulation of the carbon-concentrating mechanism in Chlamydomonas reinhardtii
… often limited by the availability of dissolved carbon dioxide (CO$_{2(aq)}$). To overcome the slow diffusion of CO$_{2(aq)}$ as well as kinetic limitations of the primary photosynthetic carboxylase, Rubisco, carbon concentrating mechanisms (CCMs) have evolved in many aquatic photosynthetic …

Morphological and Physiological Studies of the Carbon Concentrating Mechanism in Chlamydomonas reinhardtii
… reinhardtii possesses a single-cell-based CO2-concentrating mechanism (CCM). The CCM is an important element of algal photosynthesis, metabolism, growth and biomass production, which works by increasing the concentration of inorganic carbon (Ci) in the pyrenoid, a dense RuBisCO-packed structure …

Role of the small subunit of Rubisco in the green algal phylogeny and Carbon Concentrating Mechanism expression
… organisms globally fix 111-117x1015 grams of carbon per year and around half of this global net primary production is aquatic (Behrenfeld et al., 2001; Field et al., 1998), with green algae a major contributor to this global carbon fixation. However, aquatic environments have some limitations …

A comparative analysis of C3 and C4 photosynthesis under dynamic light conditions
… can amount to up to a 40% loss in daily carbon assimilation. Although remarkable progress has been made, the vast majority of the work on dynamic light photosynthesis has been conducted in C3 species, despite the undeniable global importance of C4 crops to global food supplies. The …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… of land plants, the hornworts, have an inducible carbon concentrating mechanism (CCM), to overcome these limitations. The efficiency of the CCM is improved when RuBisCO is localised to a subcellular compartment, the pyrenoid, which is hypothesised to act as a diffusion barrier for CO2 . Although …

Engineering a Reverse C4 Photosynthetic Pathway in C3 species Arabidopsis thaliana
C4 photosynthesis is a specialised carbon concentrating mechanism that achieves higher rates of photosynthesis. Engineering C4 photosynthesis into C3 plants could improve agronomic features of staple C3 crops. Introducing the biochemistry of C4 photosynthesis is considered a key step in engineering …

Strategies to improve C4 photosynthesis, water and resource-use efficiency under different atmospheres, temperatures, and light environments
… of these traits: in C4 leaves, a biochemical carbon-concentrating mechanism significantly boosts photosynthetic efficiency and overall productivity, while improving the efficiency with which key inputs such as water or nitrogen are used. Several of the world's most important and productive …

Characterising natural genetic variation in dynamic photosynthesis and photoprotection in sorghum
… on the coordination between the C<sub>4</sub> carbon concentrating mechanism and Calvin-Benson-Bassham cycle CO<sub>2</sub> fixation. Imbalances between these cycles during stress conditions likely represent a loss of photosynthetic efficiency in the field, potentially resulting in decreased …

Energetics of maize C4 physiology under light limiting conditions
C4 plants have a biochemical carbon concentrating mechanism (CCM) that increases CO2 concentration around Rubisco in the bundle sheath (BS). Maize CCM has two CO2 delivery pathways to the Bundle Sheath (BS) (respectively via malate, MAL or aspartate, ASP); rates of PGA reduction, carbohydrate …
