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

open access: yesFrontiers 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 ...

The Second Chromosome Promotes the Adaptation of the Genus Flammeovirga to Complex Environments

open access: yesMicrobiology Spectrum, 2021
Approximately 10% of bacterial strains contain more than one chromosome; however, in contrast to the primary chromosomes, the mechanisms underlying the formation of the second chromosomes and the significance of their existence remain unclear. Species of

Markerless bacterial artificial chromosome manipulation method by red proteins of phage λ mediated homologous recombination utilizing fluorescent proteins for both positive and counter selection

open access: yesHeliyon, 2023
Manipulating viral genomes is an essential technique in reverse genetics and recombinant vaccine development. A strategy for manipulating large viral genomes involves introducing their entire genome into bacterial artificial chromosomes and employing ...

Codon usage domains over bacterial chromosomes. [PDF]

open access: yesPLoS Computational Biology, 2006
The geography of codon bias distributions over prokaryotic genomes and its impact upon chromosomal organization are analyzed. To this aim, we introduce a clustering method based on information theory, specifically designed to cluster genes according to ...

Why genes evolve faster on secondary chromosomes in bacteria. [PDF]

open access: yesPLoS Computational Biology, 2010
In bacterial genomes composed of more than one chromosome, one replicon is typically larger, harbors more essential genes than the others, and is considered primary.

Organization of the bacterial chromosome [PDF]

open access: yesMicrobiological Reviews, 1990
Recent progress in studies on the bacterial chromosome is summarized. Although the greatest amount of information comes from studies on Escherichia coli, reports on studies of many other bacteria are also included. A compilation of the sizes of chromosomal DNAs as determined by pulsed-field electrophoresis is given, as well as a discussion of factors ...

The Role of Temperate Phages in Bacterial Pathogenicity

open access: yesMicroorganisms, 2023
Bacteriophages are viruses that infect bacteria and archaea and are classified as virulent or temperate phages based on their life cycles. A temperate phage, also known as a lysogenic phage, integrates its genomes into host bacterial chromosomes as a ...

Identification of QTLs Conferring Resistance to Bacterial Diseases in Rice

open access: yesPlants, 2023
Bacterial panicle blight, bacterial leaf streak, and bacterial brown stripe are common bacterial diseases in rice that represent global threats to stable rice yields.

A Markovian analysis of bacterial genome sequence constraints [PDF]

open access: yesPeerJ, 2013
The arrangement of nucleotides within a bacterial chromosome is influenced by numerous factors. The degeneracy of the third codon within each reading frame allows some flexibility of nucleotide selection; however, the third nucleotide in the triplet of ...

Chromosomal Location Determines the Rate of Intrachromosomal Homologous Recombination in Salmonella

open access: yesmBio, 2021
Bacterial chromosomes frequently carry multiple copies of genes at separate chromosomal locations.
