Phylogenies of the 16S rRNA gene and its hypervariable regions lack concordance with core genome phylogenies

open access: yesMicrobiome, 2022
Background The 16S rRNA gene is used extensively in bacterial phylogenetics, in species delineation, and now widely in microbiome studies. However, the gene suffers from intragenomic heterogeneity, and reports of recombination and an unreliable ...

Epistasis, core-genome disharmony, and adaptation in recombining bacteria. [PDF]

open access: yesmBio
ABSTRACT Recombination of short DNA fragments via horizontal gene transfer (HGT) can introduce beneficial alleles, create genomic disharmony through negative epistasis, and create adaptive gene combinations through positive epistasis.

Population structure analysis and laboratory monitoring of Shigella by core-genome multilocus sequence typing

open access: yesNature Communications, 2022
The laboratory surveillance of bacillary dysentery is based on a standardised Shigella typing scheme that classifies Shigella strains into four serogroups and more than 50 serotypes on the basis of biochemical tests and lipopolysaccharide O-antigen ...

The cyanobacterial genome core and the origin of photosynthesis [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
Comparative analysis of 15 complete cyanobacterial genome sequences, including “near minimal” genomes of five strains of Prochlorococcus spp., revealed 1,054 protein families [core cyanobacterial clusters of orthologous groups of proteins (core CyOGs)] encoded in at least 14 of them.

Core resources for genome analysis

open access: yes, 2021
The Wellcome Sanger Institute will sequence and assemble tens of thousands of genomes across the next decade through large-scale biodiversity sequencing projects such as Darwin Tree of Life. The projects span the entire tree of eukaryotic life, and the genomes will enable new and unprecedented science.

Optimisation of the core subset for the APY approximation of genomic relationships [PDF]

open access: yesGenetics Selection Evolution, 2022
Abstract Background By entering the era of mega-scale genomics, we are facing many computational issues with standard genomic evaluation models due to their dense data structure and cubic computational complexity. Several scalable approaches have been proposed to address this challenge, such as the Algorithm for Proven ...

Aggregation and disaggregation features of the human proteome

open access: yesMolecular Systems Biology, 2020
Protein aggregates have negative implications in disease. While reductionist experiments have increased our understanding of aggregation processes, the systemic view in biological context is still limited.

Thermal proteome profiling for interrogating protein interactions

open access: yesMolecular Systems Biology, 2020
Thermal proteome profiling (TPP) is based on the principle that, when subjected to heat, proteins denature and become insoluble. Proteins can change their thermal stability upon interactions with small molecules (such as drugs or metabolites), nucleic ...

BE4max and AncBE4max Are Efficient in Germline Conversion of C:G to T:A Base Pairs in Zebrafish

open access: yesCells, 2020
The ease of use and robustness of genome editing by CRISPR/Cas9 has led to successful use of gene knockout zebrafish for disease modeling. However, it still remains a challenge to precisely edit the zebrafish genome to create single-nucleotide ...
