The nature of the phycobilisome–photosystem II supercomplex on the native thylakoid determined with cryo-electron tomography at an unprecedented resolution reveals that one phycobilisome interconnects with six photosystem monomers.
The circadian clock of Synechococcus elongatus PCC7942 schedules the activity of the transcription factor RpaA, which controls key events in carbon metabolism that contribute to cell fitness in conditions mimicking the natural environment.
Noisy circadian clocks in Anabaena, coupled by cell-cell communication, display high spatio-temporal coherence and can be robustly described by incorporating demographic noise in a theoretical model of coupled clock arrays.
Cyanobacteria cope with both predictable day/night changes and natural fluctuations in light during the day by adjusting the expression dynamics of circadian-clock-controlled genes via a network of transcriptional regulators.
Phototrophic growth laws are elucidated by combining computational modeling and experiments for quantitative evaluation of cellular physiology, morphology and proteome allocation across a wide range of light conditions.
Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.
The regulatory switch from protection to assimilation, which plants use to exploit natural, fluctuating light, involves movement of the enzyme ferredoxin:NADP(H) oxidoreductase between chloroplast membrane complexes.
