Glycogen removal enhances ethylene production in Synechocystis sp. PCC 6803 but exposes a 2-oxoglutarate-GS-GOGAT-phosphate constraint

This study shows that removing glycogen in Synechocystis sp. PCC 6803 increases ethylene production but creates a metabolic constraint involving 2-oxoglutarate, GS-GOGAT, and phosphate.

Metabolic cost as a determinant of light quality acclimation: a full-PAR characterization of the CA3 cyanobacterium Nostoc sp. CCAP 1453/38

This study characterizes the spectral acclimation strategies of a CA3 cyanobacterium across the full PAR range, showing that metabolic cost influences the type of light quality response.

Estimating the redox state of the plastoquinone pool in algae and cyanobacteria via OJIP fluorescence: perspectives and limitations

This paper evaluates the OJIP fluorescence method for semi-quantitative estimation of PQ-redox in algae and cyanobacteria, showing its applicability to both dark- and light-acclimated samples.

The new phycobilisome linker protein ApcI regulates high light adaptation in Synechocystis sp. PCC 6803

This study identifies ApcI as a phycobilisome linker protein in Synechocystis sp. PCC 6803 that regulates high light adaptation by replacing ApcG and interacting with photosystem II.

A minimal model of protein allocation during phototrophic growth

The paper develops a minimal kinetic model of cyanobacterial phototrophic growth to study protein allocation trade-offs and derives growth laws similar to heterotrophic organisms with key differences due to light energy and carbon uptake.
