Spatial isolation of Rubisco is a crucial component of most carbon concentrating mechanisms, and the model green alga Chlamydomonas reinhardtii is no exception. Starting from the observation that Rubisco itself is involved in pyrenoid formation, I have investigated Rubisco protein-protein interactions in molecular transformants through analysis of isolated protein as well as whole cell extracts. Using a variety of proxies for efficiency of light use (as electron transport rates), I have also analysed the impact of the pyrenoid on photosynthetic physiology. Collectively these two parts of my project provide a greater understanding of pyrenoid structure and function, give further support to the notion of the pyrenoid as central to concentrating carbon while also implicating further functions for this enigmatic organelle.
