Molecular Physiology of the Chlamydomonas Pyrenoid
… microcompartment, the chloroplastic pyrenoid. Despite a long history of research, this enigmatic structure lacks a full definition both in terms of physiological function as well as molecular composition. The work presented here used a unique set of pyrenoid-less mutants (which differ …

Physiological and molecular determinants of the Chlamydomonas reinhardtii pyrenoid
… is localised to a subcellular compartment, the pyrenoid, which is hypothesised to act as a diffusion barrier for CO2 . Although the pyrenoid is a major player in global carbon balance (we estimate 10-15% of NPP), it is one of the few remaining prominent cellular features without a precise …

Morphological and Physiological Studies of the Carbon Concentrating Mechanism in Chlamydomonas reinhardtii
… concentration of inorganic carbon (Ci) in the pyrenoid, a dense RuBisCO-packed structure within the chloroplast. This suppresses RuBisCO oxygenase activity and associated photorespiration. The enhanced efficiency of CO2 assimilation in the pyrenoid via CCM had been modelled theoretically as a …

Regulation of the carbon-concentrating mechanism in Chlamydomonas reinhardtii
… central chloroplast microcompartment called the pyrenoid. In addition to changes in gene expression, acclimation to low CO2 is accompanied by alterations to metabolism, physiology and even cellular ultrastructure. However, mechanisms governing the regulation and interaction of these molecular …

Role of the small subunit of Rubisco in the green algal phylogeny and Carbon Concentrating Mechanism expression
… the Rubisco micro-compartment is called the pyrenoid and together with active inorganic carbon transporters and strategically located carbonic anhydrases, elevated CO2 within the pyrenoid improves photosynthetic efficiency. Most photosynthetic organisms have an hexadecameric Rubisco …

Cytology and ultrastructure of eustigmatophyceae
… the nuclear surface and the chloroplast and the pyrenoid divide. Cytokinesis seems to occur by a cleavage furrow. My reconstruction of the flagellar root system in Eustigmatophyceae shows sufficient similarities with the flagellar, roots of other heterokont algal and fungal classes to justify …
