Reconstitution of Archaeal Membrane Lipid Biosynthesis in Bacterial and Eukaryotic Hosts
Published: April 28, 2026 10:00
The membrane lipids of archaea differ from those of bacteria and eukarya in backbone stereochemical configuration, chemical linkage type, and hydrophobic chain structure, a fundamental dichotomy termed the lipid divide. Synthetic biology and metabolicā¦
A new family of rolling-circle replication endonucleases widespread in archaeal viruses and plasmids
Published: April 25, 2026 10:00
Archaea possess a remarkably diverse mobilome, but for many archaeal viruses and plasmids, even the basic processes, such as genome replication, remain poorly understood. Here, we characterize a previously uncharacterized family of putative rolling-circleā¦
Systematic screening of archaeal MazF homologs reveals Tth-MazF1, a versatile, sequence-specific ribonuclease from Thermococcus thioreducens
Published: April 25, 2026 10:00
Nucleotide- and sequence-specific ribonucleases are essential tools for dissecting RNA structure, modification, and composition, yet the enzymatic repertoire available for high-resolution RNA analysis remains limited. Here, we systematically screened 186ā¦
Halophilic bacteria and archaea in salinity-resilient agriculture: mechanisms and multi-omics perspectives
Published: April 16, 2026 10:00
Soil salinization due to anthropogenic activity and climate change is a bottleneck to the global agricultural yield and food security. Conventional approaches for mitigating salt stress, including utilization of chemical fertilizers, have shown limitedā¦
Carbon monoxide metabolism in freshwater anaerobic methanotrophic archaea
Published: April 14, 2026 10:00
Anaerobic methanotrophic archaea mitigate methane emissions in anoxic environments as key members of the biological methane filter. Despite their ecological significance, physiology of anaerobic methanotrophs remains poorly understood. Here, we demonstrateā¦
Cracking donuts and sorting lipids: Geometry controls archaeal membrane stability and lipid organization
Published: April 8, 2026 10:00
Cells are defined by lipid membranes that differ in their structure across the tree of life. While the membranes of most bacteria and eukaryotes consist of single-headed bilayer lipids, the membranes of archaea are composed of mixtures of single-headedā¦
Diversity of Archaea
Published: March 26, 2026 10:00
Archaea are prokaryotes that represent a unique evolutionary lineage distinct from bacteria and eukaryotes. Once thought to exist only in extreme environments, archaea inhabit a wide range of habitats, including soil, marine environments, and the digestiveā¦
Microbial Evolution and Systematics: Archaea and Bacteria
Published: March 26, 2026 10:00
The origin of life on Earth is a profound biological question, with Bacteria and Archaea-the two principal prokaryotic lineages-central to the inquiry. Together, they represent microbial diversity and offer insights into Earth's earliest biosphere andā¦
Biotechnological Applications of Archaea
Published: March 26, 2026 10:00
Archaea are the "silent and unseen majority of life" with an extraordinary capacity to live in some of the most unfavorable habitats in nature, and continue to exist in regions with extreme features that are inhospitable to most other living organisms.ā¦
Diversity and evolution of archaeal immune strategies
Published: March 14, 2026 10:00
Archaeal antiviral defense systems remain poorly characterized despite recent advances in understanding prokaryotic immunity. Here, we analyze 7747 archaeal genomes, the largest and most diverse dataset to date, revealing a striking disparity in defenseā¦
