Sensing of Inorganic Carbon Limitation in Synechococcus PCC7942 Is Correlated with the Size of the Internal Inorganic Carbon Pool and Involves Oxygen

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


Freshwater cyanobacteria are subjected to large seasonal fluctuations in the availability of nutrients, including inorganic carbon (Ci). We are interested in the regulation of the CO2-concentrating mechanism (CCM) in the model freshwater cyanobacterium Synechococcus sp. strain PCC7942 in response to Ci limitation; however, the nature of Ci sensing is poorly understood. We monitored the expression of high-affinity Ci-transporter genes and the corresponding induction of a high-affinity CCM in...[Show more]
