Regulation of cyanobacterial CO2-concentrating mechanisms through transcriptional induction of high-affinity Ci-transport systems

Woodger, Fiona; Badger, Murray; Price, Graeme (Dean)


Approximately 50% of global CO2-based productivity is now attributed to the activity of phytoplankton, including ocean-dwelling cyanobacteria. In response to inherent restrictions on the rate of CO 2 supply in the aquatic environment, cyanobacteria have evolved a very efficient means of capturing inorganic carbon (Ci), as either CO2 or HCO3- for photosynthetic carbon fixation. This capturing mechanism, known as a CO2-concentrating mechanism (CCM), involves the operation of active CO2 and HCO 3-...[Show more]
