New algorithms for structure informed genome rearrangement [PDF]
Algorithms for Molecular Biology, 2023 We define two new computational problems in the domain of perfect genome rearrangements, and propose three algorithms to solve them. The rearrangement scenarios modeled by the problems consider Reversal and Block Interchange operations, and a PQ-tree is ...

Dynamics of genome rearrangement in bacterial populations. [PDF]
PLoS Genetics, 2008 Genome structure variation has profound impacts on phenotype in organisms ranging from microbes to humans, yet little is known about how natural selection acts on genome arrangement.

Heterogeneous rates of genome rearrangement contributed to the disparity of species richness in Ascomycota [PDF]
BMC Genomics, 2018 Background Chromosomal rearrangements have been shown to facilitate speciation through creating a barrier of gene flow. However, it is not known whether heterogeneous rates of chromosomal rearrangement at the genome scale contributed to the huge ...

A Novel Virus-Like Agent Originated From Genome Rearrangement of Porcine Circovirus Type 2 (PCV2) Enhances PCV2 Replication and Regulates Intracellular Redox Status In Vitro [PDF]
Frontiers in Cellular and Infection Microbiology, 2022 Genome rearrangement occurs to porcine circovirus type 2 (PCV2) during in vitro and in vivo infections, and a number of rearranged PCV2 genomes have been isolated and characterized. This study was conducted to investigate the role of the rearranged PCV2 (

Genome rearrangement algorithms [PDF]
, 2011 With the increasing amount of sequenced genomes, a comparison of species based on these data becomes more and more interesting. In contrast to the classical approach, where only point mutations were considered, genome rearrangement problems ignore small mutations and only consider large-scale mutations that change the gene order on the chromosomes ...

ParIS Genome Rearrangement server [PDF]
Bioinformatics, 2004 Abstract Summary: ParIS Genome Rearrangement is a web server for a Bayesian analysis of unichromosomal genome pairs. The underlying model allows inversions, transpositions and inverted transpositions. The server generates a Markov chain using a Partial Importance Sampler technique, and samples trajectories of mutations from this chain ...

Analysis of local genome rearrangement improves resolution of ancestral genomic maps in plants [PDF]
BMC Genomics, 2020 Background Computationally inferred ancestral genomes play an important role in many areas of genome research. We present an improved workflow for the reconstruction from highly diverged genomes such as those of plants.

A Path-Deformation Framework for Determining Weighted Genome Rearrangement Distance [PDF]
Frontiers in Genetics, 2020 Measuring the distance between two bacterial genomes under the inversion process is usually done by assuming all inversions to occur with equal probability. Recently, an approach to calculating inversion distance using group theory was introduced, and is

Genome Rearrangement and Planning: Revisited
Proceedings of the International Conference on Automated Planning and Scheduling, 2010 Evolutionary trees of species can be reconstructed by pairwise comparison of their entire genomes. Such a comparison can be quantified by determining the number of events that change the order of genes in a genome. Earlier Erdem and Tillier formulated the pairwise comparison of entire genomes as the problem of planning rearrangement ...

Genome rearrangements with duplications [PDF]
BMC Bioinformatics, 2010 Finding sequences of evolutionary operations that transform one genome into another is a classical problem in comparative genomics. While most of the genome rearrangement algorithms assume that there is exactly one copy of each gene in both genomes, this does not reflect the biological reality very well - most of the studied genomes contain duplicated ...
