LSU Doctoral Dissertations
The green alga Chlamydomonas reinhardtii possesses a CO2 concentrating mechanism (CCM) which helps in successful acclimation to low CO2 conditions. One of the main aspects of the CCM is bringing in inorganic carbon (Ci) into the cell as bicarbonate using Ci transporters. Current models of the CCM postulate that a series of ion transporters bring HCO3- from outside the cell to the thylakoid lumen where the carbonic anhydrase, CAH3, dehydrates accumulated HCO3- to CO2, raising the CO2 concentration for Rubisco. Previously, HCO3- transporters have been identified at both the …
