The paper investigates the impact of GGCC methylation on gene expression in Synechocystis sp. PCC 6803, finding methylation-dependent changes in over 300 genes.

The paper examines how picocyanobacterial strains from different salinities adapt their growth and metabolism across varying salinity and light conditions.

This paper characterizes the function of the cyanobacterial gene ssr3189 by analyzing its deletion mutant, revealing its role in linking translation with metabolic control and RNA decay.

This study revisits the claim of the Entner-Doudoroff pathway in Synechocystis, showing that while the aldolase is present, the full pathway is absent due to missing enzymes and experimental errors.

This study shows that microcystin (MC) in Microcystis aeruginosa enhances carbon fixation by activating the carbon-concentrating mechanism (CCM) and altering photosynthetic processes under fluctuating light conditions.

The paper identifies SbtC as a small protein involved in the cyanobacterial CO2 concentrating mechanism, showing it forms a trimeric complex with SbtA and SbtB to regulate bicarbonate exchange.

The paper investigates the role of c-di-AMP and SbtB in cyanobacterial diurnal metabolism, finding that their disruption leads to metabolic dysregulation and diurnal lethality.

This paper develops a GC-MS-based method to measure PEPC activity in vivo by analyzing positional 13C enrichment in aspartate from Synechocystis cultures.

This study shows that RUBISCO activity in Synechocystis is regulated by RuBP availability, with CP12 inactivating the CBB cycle during darkness and affecting RuBP levels.

This study identifies FBPase in Synechocystis as a monofunctional enzyme that supports heterotrophic growth without redox regulation, distinct from the bifunctional F/SBPase.

This paper develops a method to distinguish RUBISCO activity from CBB cycle activities by analyzing carbon positional labeling in 3PGA using GC-MS after 13CO2 labeling.

The paper manipulates photorespiration in Arabidopsis guard cells and finds it significantly affects stomatal behavior, growth, and photosynthesis.

The paper shows that m4C DNA methylation regulates hemJ expression in Synechocystis, affecting tetrapyrrole biosynthesis and pigmentation.

The paper identifies a SulP-family bicarbonate transporter in a cyanobacterial endosymbiont of a diatom using gene complementation in a mutant strain.

This study identifies SbtB as a redox-regulated apyrase that modulates bicarbonate transporter SbtA activity in cyanobacteria by integrating metabolic and carbon status signals.

This study integrates transcriptomic, proteomic, and metabolomic data from Synechocystis sp. PCC 6803 to characterize the salt stress response, identifying key regulatory elements and metabolic changes.
