Genome rearrangements detected in the three Vibrio genomes were coherent with earlier studies. Through this review, we aim to highlight the importance of the less explored field of SVs in prokaryotic genomes and 150 impact.


We also describe their potential applications in the emerging fields of synthetic biology and genome engineering. Although they were high on throughput, they were limited by detecting only small copy-number variants Iafrate et al.

Mugsy’s performance was evaluated on 57 E. Some of the commonly used analytical ways of detecting SVs. Comparing rearrangements in multi-chromosome genomes proved to be a more daunting task. Though many variant calling technologies have enabled the identification and characterization of SVs Skovgaard et al.

For instance, the reversible switching on—off of colony variation in S. The availability of genome editing tools like ZF-TFs zinc finger transcription factors; Gommans et al.

Engineering zinc finger protein transcription factors: Sign In or Create an Account. Large-scale rearrangements in closely related strains of a species, for example, in the case of Yersinia pestishave shown to significantly contribute to the evolution, divergence and pathogenicity of the organism Liang et al. Localized remodeling of the Escherichia coli chromosome: The availability of datasets in the public domain for a number of prokaryotic species Tatusova et al.


Deletions entail loss of a genomic segment, and could be intragenic, wherein they result in inactivation of a gene or the loss of one or more functional domains or an altered gene function.

Scs Neisseria species contains an extensive array of repetitive sequences such as tandem repeats and IS elements spread throughout its genome. Conceptual overview of functional consequences of SVs. Discovery of statistically significant post-translational modification motifs.

Most of the SVs such as inversions, deletions and translocations have been largely studied in context of genetic diseases in eukaryotes. Mobile elements create structural variation: The functional consequences of insertions are governed by the information content of the inserted fragment and ssvs context of the genomic segment of insertion Dobinsky et al.

Duplication generally results in gain of a copy of the DNA segment carrying information Roth et al.

1501-600 – Unknown

In another study, experimental deletion of the mutS gene of E. Large chromosomal inversions were initially considered to be rare in bacteria Roth et al.

Genome rearrangements in prokaryotes have also been studied in relation to their phenotypic outcomes. The functional consequence of the duplication could vary depending on the information content of the duplicated genomic segment and also on the context in which it is inserted Reams and Neidle, An attenuated strain of Bacillus anthracis CDC has a large chromosomal inversion and altered growth kinetics.

Deletions encompassing loss of essential genes or gene components may significantly hamper cell viability Jasin and Schimmel, The symmetrical organization of bacterial chromosome along the replichores Eisen et al. There have been some important functional consequences of repetitive elements in chromosome rearrangements.

Additionally, the bacterial species N eisseria gonorrhoeaewhich contains fewer repeat elements than N. In some cases, the rearrangement could encompass genes, even operons or a large number of genes depending on the size of the rearranged fragment Hastings et al.


Apart from creating SVs in the genome, TEs and IS elements can also influence the expression of the genes, depending on the context of sv gene in relation to the element. This includes a wide variety of chromosomal contexts such as sequence and structural motifs, repeat elements, insertion sequence IS elements and transposon elements TE Mahillon circu,ar Chandler, ; Treangen et al.

In the following section, we review some of these algorithms and techniques with their circulad applications and limitations. The deciphering of the genomic variability in E. BratNextGen functions by creating a Bayesian clustering model, to detect recombination in taxa along with resampling.

The major understanding on the genomic landscape of SVs was facilitated by the availability of sequencing technologies coupled with computational algorithms to map and identify SVs at a circukar higher resolution Skovgaard et al. The last possibility has been explored by Nagarajan et al. Over the years, several approaches have been developed to detect and characterize SVs.

This type of SV is particularly more evident and common in multi-chromosomal bacteria, where the smaller secondary chromosomes evolve more rapidly Morrow and Cooper, Sv briefly describe the various types of SVs, discuss their probable molecular mechanisms of formation, advances in the development of tools and techniques to detect SVs and also their phenotypic consequences in context of prokaryotic genomes.

Large inversions, which disturb the symmetry around the constrained chromosomal regions, i. In contrast to single-nucleotide variations, SVs provide a much deeper insight into organization of bacterial genomes at a much better resolution.
