The overall energy conversion efficiency is calculated for a bacterial vesicle that harvests solar energy for ATP production on the basis of an atomic-detail structural model.

The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.

Guanosine tetraphosphate (ppGpp) is a pivotal regulator of chloroplast activity that is required for acclimation to nitrogen limitation in the model plant Arabidopsis.

Melainabacteria, a candidate phylum related to Cyanobacteria, has been identified in gut and sediment samples by genomic analysis.

Revisiting limitations in time-resolved X-ray free-electron laser structures of the bacterial photosynthetic reaction center uncovers their irrelevance to proposed structural changes in electron transfer dynamics.

The structures responsible for photosynthesis in bacteria use the nucleoid and two unique proteins as a scaffold to position themselves.

Investigations of the reaction center (RC)-light harvesting (LH) complex from an ancient chlorosome-less anoxygenic phototroph Roseiflexus castenholzii reveal the structural basis by which carotenoids assembly regulates the architecture and quinone exchange of bacterial RC-LH complex.

A novel B12 containing photoreceptor is synthesized as two different isoforms that interact with the same transcription factor, with one isoform directing activation and the other promoting repression of photosystem synthesis.

A bacterial CO₂ concentrating mechanism enables Escherichia coli to fix CO₂ from ambient air into biomass.

Phylogenomics reveals the timeline over which marine bacteria and archaea colonized the oceans and shows the geological context of their diversification.
