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 svw the organism Liang et al. The availability of genome editing tools like ZF-TFs zinc finger transcription factors; Gommans et al.
A comprehensive list of sequence signatures that can be used to efficiently call SVs is detailed by Alkan et al. Though the high-throughput technologies have significantly contributed to the understanding of the repertoire of SVs in prokaryotic genomes, the problem of SV detection has always remained challenging as none of the methods can appropriately address the complexity of repetitive regions found in genomes.
Next-generation VariationHunter introduced in Hormozdiari et al.
Genome rearrangements in prokaryotes have also been studied in relation to their phenotypic outcomes. Typically, inversions involve two breakpoints and realignment of the flipped ends.
It is an enhanced version of previous algorithms GeneOrder Mazumder et al. More details about these tools, what they detect and their advantages and limitations are provided in Supplementary Table S2. The FFBI algorithm was designed to analyze genome rearrangements arising as a result of chromosome fusion, fission and blocks interchanges. Close mobile search navigation Article navigation. The Neisseria species contains an extensive array of repetitive sequences such as tandem repeats and IS elements spread throughout its genome.

In this review, we provide a comprehensive overview of the present understanding of SVs in general and in the context of prokaryotic genomes.
The balanced SVs comprise inversions. In organisms with repetitive DNA, homologous repetitive segments within one chromosome or on different chromosomes can serve as sites for illegitimate crossing-over.
In addition, the molecular, cellular and mechanistic insights into their formation and resultant phenotype remain largely obscure Weischenfeldt et al. A large number of studies focusing on variations in prokaryotic genomes have been majorly concentrated on single-nucleotide variations and small insertion—deletion events Sun et al. Among the different types of genetic variations found in genomes, structural variants have remained the most difficult to identify and interpret.
Large chromosomal inversions circulra initially considered to be rare in bacteria Roth et al. The effects of deletions are highly irreversible and can be explained by the loss of functions. Modularized framework for detecting 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, The availability of a gamut of new technologies for high-throughput nucleotide sequencing have opened up new opportunities toward understanding genome structure and their variations.
In bacterial genomes, chromosomal rearrangements can change the distance of a gene from the origin of chromosome replication oriC leading to altered 11501 copy number and thereby affecting its expression Rebollo et al.
The functional consequences of the SVs could therefore vary widely.
Most of the SVs such as inversions, deletions and circuoar have been largely studied in context of genetic diseases in eukaryotes. The primary one being methodologies to phenotypically screen large populations of prokaryotes and secondly the computational algorithms, which can decipher, map and report genomic variations at large scale for these screens in short time.
Although evolutionary implications of SVs have been shown at large, few studies have highlighted their functional and biological importance. SVs involve long stretches of DNA that can span from a few kilobases to sometimes up to millions of base pairs in length. The third class of unbalanced SVs is the insertions.
SVs involving IS elements have been shown to activate the expression of neighboring genes Hubner and Hendrickson, ; Mahillon and Chandler, Site-specific recombination circulad such as the Cre-lox system has been used to create deletions in E.
It can simulate five types of most common SVs for practically any type of genome. Linking sequence patterns and functionality of alpha-helical antimicrobial peptides. Computational methods for discovering structural variation with next-generation sequencing.
