Metagenomic Insights Into the Ecology, Taxonomy and Metabolic Capabilities of ‘Candidatus Darwinibacteriales’ Ord. Nov. (Formerly MBA03), a Potential Key Player in Anaerobic Digestion

open access: yesMicrobial Biotechnology, Volume 18, Issue 12, December 2025.
Metagenomic analysis of anaerobic digesters revealed a dominant, uncultured bacterial taxon—MBA03—now proposed as ‘Candidatus Darwinibacteriales’ ord. nov. This newly defined order includes potential syntrophic acetate‐oxidising bacteria (SAOB), suggesting a key role in methane production.

NirA is a Cyanide‐Tolerant Nitrite Reductase Which Protects Pseudomonas aeruginosa From Self‐Poisoning

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Infection‐mediated oxygen limitation triggers P. aeruginosa cyanide production. Cyanide inhibits heme‐dependent enzymes, including NirB and NirS of the assimilatory and dissimilatory nitrate reduction pathways. The presence of cyanide upregulates nirA, which facilitates cyanide‐tolerant nitrite reduction, detoxifying the respiratory inhibitor nitrite ...

Bacterial fitness for plant colonization is influenced by plant growth substrate

open access: yesNew Phytologist, Volume 248, Issue 6, Page 3168-3190, December 2025.
Summary Despite advances in our understanding of bacterial plant colonization, the extent to which growth substrate influences the molecular mechanisms enabling bacteria to efficiently colonize plants remains poorly understood. To address this, we used randomly barcoded transposon mutagenesis sequencing (RB‐TnSeq) in Paraburkholderia graminis OAS925 ...

Molecular Mechanism by Which the BrFIT2–BrbHLH–BrIRT1 Module Synergistically Regulates Iron Absorption in Brassica rapa ssp. Pekinensis

open access: yesPlant Biotechnology Journal, Volume 23, Issue 12, Page 5600-5615, December 2025.
ABSTRACT Iron is essential for plant photosynthesis and human health, yet Brassica rapa ssp. pekinensis exhibits significantly lower iron content compared to other leafy vegetables, and its iron uptake mechanisms are not well understood. This study elucidates the molecular mechanisms governing iron uptake by investigating the roles of the iron ...

Protein acetylation in archaea, bacteria, and eukaryotes [PDF]

open access: yes, 2010
Proteins can be acetylated at the alpha-amino group of the N-terminal amino acid (methionine or the penultimate amino acid after methionine removal) or at the epsilon-amino group of internal lysines.

Hidden diversity: Transcriptomic and photosynthetic variation among common ‘wild type’ Chlamydomonas strains

open access: yesThe Plant Journal, Volume 124, Issue 5, December 2025.
SUMMARY The unicellular green alga Chlamydomonas reinhardtii is a widely studied reference organism, particularly in photosynthesis research. It employs photoprotective mechanisms, such as state transitions (ST) and non‐photochemical quenching (NPQ), to cope with rapid light changes. Most widely used strains share a recent common ancestor yet differ by
