Molecular characterization of Borrelia persica, the agent of tick borne relapsing fever in Israel and the Palestinian Authority. [PDF]

open access: yesPLoS ONE, 2010
The identification of the Tick Borne Relapsing Fever (TBRF) agent in Israel and the Palestinian Authority relies on the morphology and the association of Borrelia persica with its vector Ornithodoros tholozani. Molecular based data on B. persica are very

Polymorphism and gene conversion of the 16S rRNA genes in the multiple rRNA operons ofVibrio parahaemolyticus [PDF]

open access: yesFEMS Microbiology Letters, 2005
The genome sequence of a strain of Vibrio parahaemolyticus holds 11 copies of rRNA operons (rrn) with identical 16S rRNA genes (rrs). Conversely, the species type strain contains two rrs classes differing in 10 nucleotide sites within a short segment of 25 bp.

454-Pyrosequencing: A Molecular Battiscope for Freshwater Viral Ecology [PDF]

open access: yes, 2010
Viruses, the most abundant biological entities on the planet, are capable of infecting organisms from all three branches of life, although the majority infect bacteria where the greatest degree of cellular diversity lies.

Transposition of a chromosomal segment bounded by redundant rRNA genes into other rRNA genes in Escherichia coli [PDF]

open access: yesJournal of Bacteriology, 1982
We have constructed several mutants of Escherichia coli which have the chromosomal segment between the directly repeated rrnB and rrnE genes deleted from the normal position and transposed into another one of the seven redundant rRNA genes. We have examples where the transposition has been into rrnC, rrnD, rrnG, and rrnH.

Mobile resistome of human gut and pathogen drives anthropogenic bloom of antibiotic resistance [PDF]

open access: yes, 2020
BACKGROUND:The impact of human activities on the environmental resistome has been documented in many studies, but there remains the controversial question of whether the increased antibiotic resistance observed in anthropogenically impacted environments ...

Phylogenetic position of the Hypsugo alaschanicus based on complete mitochondrial genome sequences

open access: yesMitochondrial DNA. Part B. Resources, 2019
The mitogenome of the Hypsugo alaschanicus is a circular module of 16,911 bp, which consists of 37 genes, containing 13 protein-coding genes, 22 tRNA genes, and 2 rRNA genes (12S rRNA and 16S rRNA), and a control region. The mitogenome of H. alaschanicus

Analyses of rRNA gene chromatin in cell cycle arrested Saccharomyces cerevisiae cells

open access: yesData in Brief, 2019
The existence of two chromatin structures in the rDNA locus was previously demonstrated for a large variety of organisms, ranging from yeast to human. In yeast there are about 150–200 rRNA genes organized in tandem repeats.

Conditional inactivation of Upstream Binding Factor reveals its epigenetic functions and the existence of a somatic nucleolar precursor body. [PDF]

open access: yesPLoS Genetics, 2014
Upstream Binding Factor (UBF) is a unique multi-HMGB-box protein first identified as a co-factor in RNA polymerase I (RPI/PolI) transcription. However, its poor DNA sequence selectivity and its ability to generate nucleosome-like nucleoprotein complexes ...
