Role of archaea in aquaculture: prospects and challenges
The success of aquaculture production greatly depends on the health status of aquatic species and the proper management of the water quality. The...

Expanded phylogeny of extremely halophilic archaea shows multiple independent adaptations to hypersaline environments
Extremely halophilic archaea (Haloarchaea, Nanohaloarchaeota, Methanonatronarchaeia and Halarchaeoplasmatales) thrive in saturating salt...

Archaea: A Goldmine for Molecular Biologists and Evolutionists
The rebuttal of the prokaryote–eukaryote dichotomy and the elaboration of the three domains concept by Carl Woese and colleagues has been a...

An Archaic Approach to a Modern Issue: Endophytic Archaea for Sustainable Agriculture
Archaea have existed for over 3.5 billion years, yet they were detected in the plant endosphere only in the recent past and still, not much is known...
-
Viperin immunity evolved across the tree of life through serial innovations on a conserved scaffold
Evolutionary arms races between cells and viruses drive the rapid diversification of antiviral genes in diverse life forms. Recent discoveries have...

Soils and sediments host Thermoplasmata archaea encoding novel copper membrane monooxygenases (CuMMOs)
Copper membrane monooxygenases (CuMMOs) play critical roles in the global carbon and nitrogen cycles. Organisms harboring these enzymes perform the...

Progress and Challenges in Studying the Ecophysiology of Archaea
It has been less than two decades since the study of archaeal ecophysiology has become unshackled from the limitations of cultivation and amplicon...

Characterization of Multi-Domain Proteins in the ArsR/SmtB Family of Transcriptional Regulators
AbstractStudies centered on single-domain proteins revealed several fundamental characteristics about how they work, but the multimeric proteins are...

Ultra-small bacteria and archaea exhibit genetic flexibility towards groundwater oxygen content, and adaptations for attached or planktonic lifestyles
Aquifers are populated by highly diverse microbial communities, including unusually small bacteria and archaea. The recently described...

Protein length distribution is remarkably uniform across the tree of life
BackgroundIn every living species, the function of a protein depends on its organization of structural domains, and the length of a protein is a...
-
Ammonia-oxidizing archaea in biological interactions
The third domain Archaea was known to thrive in extreme or anoxic environments based on cultivation studies. Recent metagenomics-based approaches...

Unique mobile elements and scalable gene flow at the prokaryote–eukaryote boundary revealed by circularized Asgard archaea genomes
Eukaryotic genomes are known to have garnered innovations from both archaeal and bacterial domains but the sequence of events that led to the complex...

Archaea: An Agro-Ecological Perspective
Microorganisms inhabiting bulk soil and rhizosphere play an important role in soil biogeochemical cycles leading to enhanced plant growth and...

Single-Stranded DNA-Binding Proteins in the Archaea
Single-stranded (ss) DNA-binding proteins are found in all three domains of life where they play vital roles in nearly all aspects of DNA metabolism...
-
On Protein Loops, Prior Molecular States and Common Ancestors of Life
The principle of continuity demands the existence of prior molecular states and common ancestors responsible for extant macromolecular structure....

Diversity, metabolism and cultivation of archaea in mangrove ecosystems
Mangroves comprise a globally significant intertidal ecosystem that contains a high diversity of microorganisms, including fungi, bacteria and...

Origins and Functional Significance of Eukaryotic Protein Folds
Folds are the architecture and topology of a protein domain. Categories of folds are very few compared to the astronomical number of sequences....

The electronic tree of life (eToL): a net of long probes to characterize the microbiome from RNA-seq data
BackgroundMicrobiome analysis generally requires PCR-based or metagenomic shotgun sequencing, sophisticated programs, and large volumes of data....

Life Forms of Aquatic Organisms
This chapter gives a kind of minimal introduction to the organisms living in water, as far as it is needed for an ecology textbook. It will not focus...
