SUMMARY:Regulation of the carbon concentrating mechanism in Chlamydomonas 
 reinhardtii by CO2 and light  - Madeline Mitchell

DESCRIPTION:Carbon concentrating mechanisms (CCMs) occur in most unicellul
 ar aquatic photosynthetic organisms to compensate for Rubisco kinetic cons
 traints and limited availability of CO2(aq). In Chlamydomonas\, the CCM is
  induced under low CO2 in the light and comprises: active uptake of inorga
 nic carbon\, carbonic anhydrases to facilitate the interconversion of CO2 
 and HCO3-\, and the localisation of Rubisco to a chloroplast microcompartm
 ent called the pyrenoid.\n\nMy overall project aim is to provide a molecul
 ar definition of the pyrenoid and co-regulation of CCM components. In part
 icular\, the focus of my seminar will be my work on the regulation of the 
 CCM in cells grown in dark/light cycles. This novel approach puts the CCM 
 back into a more biological context and attempts to reconcile regulation a
 t the molecular level (mRNA and protein abundance and protein localisation
 ) with overall CCM activity.
