Plastid Genome Evolution Across the Roridulaceae–Sarraceniaceae Clade (Ericales) in Relation to Carnivorous Strategies

Ecology and Evolution, Volume 16, Issue 4, April 2026.
The Roridulaceae–Sarraceniaceae clade exhibits strikingly divergent carnivorous strategies, providing a framework to examine how trophic shifts influence plastid genome evolution. Comparative plastome analyses reveal recurrent ndh gene disruption across species, while Roridula gorgonias shows pronounced genomic restructuring, including elevated ...

Characterization of an archaeal ubiquitin‐like protein SAMP1

The FASEB Journal, 2013
Small archaeal modifier protein (SAMP1) structurally resembles the eukaryotic ubiquitin (Ub) and bacterial MoaD, sharing with them the β‐grasp fold and C‐terminal GlyGly motif. Our study was aimed to understand the function of SAMP1 using the haloarchaeon Haloferax volcanii as a model system.

Freeze‐dried Lactobacillus spp. improved average daily liveweight gain and reduced methane intensity in growing lambs

Journal of the Science of Food and Agriculture, Volume 106, Issue 6, Page 3857-3865, April 2026.
Abstract BACKGROUND Direct fed microbials (DFM) are natural and safe enteric methane mitigants for ruminant livestock systems. While previous studies have demonstrated the effect of Lactobacillus spp. on methane mitigation, challenges remain in effectively delivering DFM in extensive grazing systems. The objective of this experiment was to evaluate the

Reconstructed ancestral Myo-inositol-3-phosphate synthases indicate that ancestors of the Thermococcales and Thermotoga species were more thermophilic than their descendants.

PLoS ONE, 2013
The bacterial genomes of Thermotoga species show evidence of significant interdomain horizontal gene transfer from the Archaea. Members of this genus acquired many genes from the Thermococcales, which grow at higher temperatures than Thermotoga species ...

The Mystery of Two Straight Lines in Bacterial Genome Statistics. Release 2007

, 2007
In special coordinates (codon position--specific nucleotide frequencies) bacterial genomes form two straight lines in 9-dimensional space: one line for eubacterial genomes, another for archaeal genomes. All the 348 distinct bacterial genomes available in

Cryo-EM structures of the archaeal PAN-proteasome reveal an around-the-ring ATPase cycle

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Proteasomes are ATP-dependent proteases that occur in all three domains of life, and are the principal molecular machines for the regulated degradation of intracellular proteins.

The energetic consequences of oxygen fluxes in a coral reef fish

Functional Ecology, Volume 40, Issue 4, Page 844-856, April 2026.
Abstract Ocean warming elevates metabolic rates in marine ectotherms but often constrains energetic resources, causing an imbalance between supply and demand. Transient hypoxia is near‐ubiquitous across the world's coral reefs and may exacerbate this imbalance, yet its effects on the energetics of reef fishes remain poorly understood. In this study, we

Structural disorder of plasmid-encoded proteins in Bacteria and Archaea

BMC Bioinformatics, 2018
Background In the last decade and a half it has been firmly established that a large number of proteins do not adopt a well-defined (ordered) structure under physiological conditions.

Hi‐C Links Reveal Viral Activity and Infection Within the Free‐Living Microbial Community of a Secondary Chlorophyll Maximum in the Eastern Tropical North Pacific

Environmental Microbiology, Volume 28, Issue 4, April 2026.
Hi‐C sequencing was used to link viral sequences with microbial metagenome assembled genomes in the largely uncultivated waters of an oxygen‐deficient zone's secondary chlorophyll maximum within the Eastern Tropical North Pacific Ocean. ABSTRACT Oxygen‐deficient zones (ODZs) influence global nitrogen cycling as key sites for the removal of bioavailable
