ProteomicsA Spatial Interactome Reveals the Protein Organization of the Algal CO2 Concentrating Mechanism
One-third of global CO2 fixation is mediated by eukaryotic algae. Nearly all algae enhance their carbon assimilation by operating a CO2 concentrating mechanism (CCM), built around a mysterious organelle called the pyrenoid. Here, we leveraged new tools to determine the localizations of 146 candidate...

TranscriptomicsResponse of Prochlorococcus to varying CO2:O2 ratios
Carbon fixation plays a central role in determining cellular redox poise, increasingly understood to be a key parameter in cyanobacterial physiology. In the cyanobacterium Prochlorococcus--—the most abundant phototroph in the oligotrophic oceans--—the carbon-concentrating mechanism (CCM) is reduced...

GenomicsThe cAMP receptor protein, SyCRP1 acts as a transcriptional repressor of CO2-concentrating mechanism genes at high inorganic carbon levels in cyanobacteria
CO2-concentrating mechanism (CCM) is a unique adaptation that evolved in cyanobacteria for inorganic carbon (Ci) sequestration under limiting Ci levels. The CCM is based on several Ci uptake systems and the carboxysome in which RubisCO is confined in a high CO2 environment. Many CCM components are t...

TranscriptomicsGlobal Changes in Chlamydomonas Gene Expression Regulated by Carbon Dioxide and CIA5/CCM1
We used RNA-Seq to query the Chlamydomonas reinhardtii transcriptome for regulation by CO2 concentration and by the transcription regulator CIA5(CCM1). Both CO2 concentration and CIA5 are known to play roles in induction of an essential CO2-concentrating mechanism (CCM), but the degree of interactio...
