Annotated bacterial chromosomes from frame-shift-corrected long-read metagenomic data

open access: yesMicrobiome, 2019
Background Short-read sequencing technologies have long been the work-horse of microbiome analysis. Continuing technological advances are making the application of long-read sequencing to metagenomic samples increasingly feasible.

The impact of prophages on bacterial chromosomes [PDF]

open access: yesMolecular Microbiology, 2004
SummaryProphages were automatically localized in se‐quenced bacterial genomes by a simple semantic script leading to the identification of 190 prophages in 115 investigated genomes. The distribution of prophages with respect to presence or absence in a given bacterial species, the location and orientation of the prophages on the replichore was not ...

Global features of sequences of bacterial chromosomes, plasmids and phages revealed by analysis of oligonucleotide usage patterns

open access: yesBMC Bioinformatics, 2004
Background Oligonucleotide frequencies were shown to be conserved signatures for bacterial genomes, however, the underlying constraints have yet not been resolved in detail.

Remnant of Unrelated Amniote Sex Chromosomal Linkage Sharing on the Same Chromosome in House Gecko Lizards, Providing a Better Understanding of the Ancestral Super-Sex Chromosome

open access: yesCells, 2021
Comparative chromosome maps investigating sex chromosomal linkage groups in amniotes and microsatellite repeat motifs of a male house gecko lizard (Hemidactylus frenatus, HFR) and a flat-tailed house gecko lizard (H.

Quantitative analysis of replication-related mutation and selection pressures in bacterial chromosomes and plasmids using generalised GC skew index

open access: yesBMC Genomics, 2009
Background Due to their bi-directional replication machinery starting from a single finite origin, bacterial genomes show characteristic nucleotide compositional bias between the two replichores, which can be visualised through GC skew or (C-G)/(C+G ...

A decade of antimicrobial resistance in Vibrio spp.: genomic and functional insights

open access: yesMicrobiology Spectrum
Environmental pressures and repeated exposure to antimicrobials drive microbial evolution, often through genomic changes or acquisition of mobile genetic elements that enhance fitness and resistance. This has critically influenced the control of cholera,

Distribution of mononucleotide repeats in bacterial chromosomes: A/T-tracts dominate on G/C-tracts [PDF]

open access: yesКомпьютерные исследования и моделирование, 2010
This study analyzes the abundance of mononucleotide tracts of different length in 342 eubacterial and 69 archaeal chromosomes. Despite the fact that the amount of analyzed repeats depends on nucleotide content, the predominance of poly(dA)n- and poly(dT ...

Bacterial Chromosome Organization and Segregation [PDF]

open access: yesAnnual Review of Cell and Developmental Biology, 2015
If fully stretched out, a typical bacterial chromosome would be nearly 1 mm long, approximately 1,000 times the length of a cell. Not only must cells massively compact their genetic material, but they must also organize their DNA in a manner that is compatible with a range of cellular processes, including DNA replication, DNA repair, homologous ...

Organization and segregation of bacterial chromosomes [PDF]

open access: yesNature Reviews Genetics, 2013
The bacterial chromosome must be compacted more than 1,000-fold to fit into the compartment in which it resides. How it is condensed, organized and ultimately segregated has been a puzzle for over half a century. Recent advances in live-cell imaging and genome-scale analyses have led to new insights into these problems. We argue that the key feature of

Optically mapping multiple bacterial genomes simultaneously in a single run. [PDF]

open access: yesPLoS ONE, 2011
Optical mapping of bacterial chromosomes provides an unambiguous low-resolution sequence scaffold of the entire chromosome. In comparison to some techniques, such as pulse field gel electrophoresis, cost and throughput limit the application of this ...
