Comprehensive analyses of archaeal viral genomes reveal genomic characteristics, divergence, and host interactions [PDF]

Microbiome
Background The ecological significance of bacteriophages has been extensively investigated, while the role of archaeal viruses across different environments remains poorly understood.

Sulfolobus acidocaldarius, half a century of archaeal research [PDF]

Journal of Bacteriology
Since its isolation from a Yellowstone hot spring in 1972, Sulfolobus acidocaldarius has become one of the most important model organisms for archaeal biology. Initially studied for its remarkable adaptation to high temperature and low pH, it has evolved

Removal and bypass of restriction modification systems increases transformation efficiency of Thermococcus kodakarensis [PDF]

Frontiers in Microbiology
Archaea are increasingly recognized as key participants in global nutrient cycles, as idealized platforms for biotechnological applications, and as the progenitors of Eukarya.

Histone diversity in the archaeal domain of life [PDF]

Nature Communications
Two-thirds of all archaea encode histones, proteins that are ubiquitously used to structure chromatin in eukaryotes. Archaeal histone sequences are less conserved than their eukaryotic counterparts, and insight into how they structure DNA is limited to a

On the origins and variation of nucleotide skews of archaeal genomes [PDF]

Frontiers in Microbiology
We have used nucleotide skews as the proxy to understand the evolution of archaeal genomes. Our genome-wide studies using substantial datasets suggest that translational selection and the nature of the genetic code are universally conserved determinants ...

Vertical Stratification in Composition, Metabolic Potential and Co-Occurrence Networks of Archaeal Communities in Mangrove Sediments, Zhanjiang, China. [PDF]

Ecol Evol
We characterized the vertical profiles of archaeal community composition, function, co‐occurrence networks, and assembly mechanisms in mangrove sediments across six depth intervals. Deep sediments hosted higher archaeal diversity, with distinct taxonomic and functional shifts, and more stable co‐occurrence networks compared to surface layers ...

Metagenomic Insights Into Microbial Diversity of Tea Rhizosphere of the Kangra Valley [PDF]

Microbiologyopen
Tea rhizosphere microbial communities in Kangra Valley. ABSTRACT This study provides the first metagenomic assessment of microbial diversity from the tea rhizosphere of the Kangra valley. Tea rhizosphere soil samples were collected from 4 locations (Dharamshala, Baijnath, Palampur, and Joginder Nagar) of the Kangra valley.

The influence of primer choice on archaeal phylogenetic analyses based on 16S rRNA gene PCR

Brazilian Journal of Biology, 2021
Polymerase chain reaction (PCR) assays targeting 16S rRNA genes followed by DNA sequencing are still important tools to characterize microbial communities present in environmental samples.

Data on the optimization of an archaea-specific probe-based qPCR assay

Data in Brief, 2020
Estimation of archaeal numbers by use of fluorescent DNA binding dyes is challenging, because primers targeting the archaeal 16SrRNA genes readily also bind to bacterial 16S rRNA gene sequences, especially when the relative abundance of bacteria is ...

Archaeal DNA Repair Mechanisms

Biomolecules, 2020
Archaea often thrive in environmental extremes, enduring levels of heat, pressure, salinity, pH, and radiation that prove intolerable to most life. Many environmental extremes raise the propensity for DNA damaging events and thus, impact DNA stability ...
