Defense Systems and Prophage Detection in Streptococcus mutans Strains

Molecular Oral Microbiology, Volume 41, Issue 2, Page 57-68, April 2026.
ABSTRACT Although the species is extensively studied, limited data are available on antiphage defense systems (APDSs) in Streptococcus mutans. The present study aimed to explore the diversity and the occurrence of APDSs and to search for prophages in the genomes of clinical isolates of S. mutans using bioinformatics tools.

Mitogenomic Characterization and Phylogenetic Expansion of Tribe Coccinellini (Coleoptera: Coccinellidae)

Ecology and Evolution, Volume 16, Issue 3, March 2026.
This study presents the complete mitochondrial genomes of nine ladybird species from the tribe Coccinellini and compares them with 58 previously published mitogenomes. Phylogenetic analyses confirm the taxonomic placement of these species within Coccinellini.

Geometric alignment of aminoacyl-tRNA relative to catalytic centers of the ribosome underpins accurate mRNA decoding

Nature Communications, 2023
Accurate protein synthesis is determined by the two-subunit ribosome’s capacity to selectively incorporate cognate aminoacyl-tRNA for each mRNA codon.

ModuLand plug-in for Cytoscape: determination of hierarchical layers of overlapping network modules and community centrality [PDF]

, 2012
Summary: The ModuLand plug-in provides Cytoscape users an algorithm for determining extensively overlapping network modules. Moreover, it identifies several hierarchical layers of modules, where meta-nodes of the higher hierarchical layer represent ...

Decoding system for the AUA codon by tRNAIle with the UAU anticodon in Mycoplasma mobile

Nucleic Acids Research, 2013
Deciphering the genetic code is a fundamental process in all living organisms. In many bacteria, AUA codons are deciphered by tRNAIle2 bearing lysidine (L) at the wobble position.

A chromosome‐scale genome of Sarracenia purpurea reveals a significant expansion of plant defense and stress response gene families following paleopolyploidization

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Plant carnivory evolved through gene co‐option and whole genome duplications (WGDs) over millions of years in at least 13 independent flowering plant lineages, but its genetic mechanisms remain largely unknown. To elucidate these mechanisms in Sarraceniaceae, we sequenced and assembled the Sarracenia purpurea genome and conducted a comparative

Genomic Prediction and Genome‐Wide Association Analysis of Heat Tolerance for Milk Yield in Buffaloes Using a Reaction Norm Model

Journal of Animal Breeding and Genetics, Volume 143, Issue 2, Page 342-353, March 2026.
ABSTRACT The aim of this study was to evaluate the impact of incorporating genomic information on the estimation of genetic (co)variance components and the accuracy of breeding values for milk yield under varying thermal environments, and to identify SNPs associated with genes that play significant roles in heat tolerance.

Characterization and Phylogenomic Implications of the Mitochondrial Genome of Rhithrogena elasmaris (Ephemeroptera: Heptageniidae)

Ecology and Evolution, Volume 16, Issue 2, February 2026.
This study presents the first complete mitochondrial genome of Rhithrogena elasmaris, revealing its structural features and codon usage patterns. Comparative analysis with 29 other Heptageniidae species showed high genetic diversity and strong purifying selection across protein‐coding genes.

Thermodynamic and kinetic insights into stop codon recognition by release factor 1. [PDF]

, 2014
Stop codon recognition is a crucial event during translation termination and is performed by class I release factors (RF1 and RF2 in bacterial cells). Recent crystal structures showed that stop codon recognition is achieved mainly through a network of ...

Effect of Threonylcarbamoyl Modification (t⁶A) in Yeast tRNA^Arg_III on Codon‐Anticodon and Anticodon‐Anticodon Interactions [PDF]

European Journal of Biochemistry, 1981
The effect of N‐[9‐(β‐d‐ribofuranosyl) purin‐6‐ylcarbamoyl]threonine (t6A) adjacent to anticodon U*‐C‐U of yeast tRNAArgIII (where U* is a modified U), compared to its unmodified adenosine counterpart, has been evaluated by three independent methods: (a) the polynucleotide‐directed binding of tRNA on ribosomes, (b) the ribosome‐free trinucleotide ...
