We formalize a new problem variant in gene-block discovery, denoted Reference-Anchored Gene Blocks (RAGB). Given a query sequence Q of length n, representing the gene-array of a DNA element, a window size bound d on the length of a substring of interest in Q, and a set of target gene sequences \(\mathcal {T}=\{T_1 \ldots T_c\}\). Our objective is to identify gene-blocks in \(\mathcal {T}\) that are centered in a subset q of co-localized genes from Q, and contain genomes from \(\mathcal {T}\) in… 



Approximate Common Intervals in Multiple Genome Comparison

This work adopts a simple, classical graph-based approach, where the vertices of the graph represent the exact common intervals of the sequences (\ie, regions containing the same gene set), and where edges link vertices that differ by less than less than $\delta$ elements (with $\d delta$ being parameter).

Efficient Computation of Approximate Gene Clusters Based on Reference Occurrences

An efficient set distance based approach that computes approximate gene clusters by means of reference occurrences yields highly comparable results to the corresponding non-reference based approach, while its polynomial runtime allows for approximate gene cluster detection in parameter ranges that used to be feasible only with simpler, e.g., max-gap based, gene cluster models.

A hybrid gene team model and its application to genome analysis.

This paper proposes a novel hybrid pattern model that combines the set and the sequential pattern models and shows that predicted gene teams can be used for various genome analysis: operon prediction, phylogenetic analysis of organisms, contextual sequence analysis and genome annotation.

Score-based prediction of genomic islands in prokaryotic genomes using hidden Markov models

SIGI-HMM is a sensitive tool for the identification of GIs in microbial genomes that allows to interactively analyze genomes in detail and to generate or to test hypotheses about the origin of acquired genes.

An event-driven approach for studying gene block evolution in bacteria

It is shown here that the evolution of gene blocks in proteobacteria can be described by a small set of events, which include the insertion of genes into, or the splitting of genes out of a gene block, gene loss, and gene duplication.

Detecting gene clusters under evolutionary constraint in a large number of genomes

A very efficient algorithm based on a 'gene teams' model that allows genes in the clusters to appear in different orders allows us to detect conserved gene clusters under flexible evolutionary constraints in a large number of genomes.

Evaluation of genomic island predictors using a comparative genomics approach

The comparative genomics approach, IslandPick, was the most accurate, compared with a curated list of GIs, indicating that it has constructed suitable datasets, and the accuracy of several sequence composition-based GI predictors is evaluated.

The Algorithmic of Gene Teams

This paper presents two algorithms for identifying gene teams formed by n genes placed on m linear chromosomes, which run in O(m2n2) time, and follows a direct and simple approach and a more tricky one, which requires linear space.

IslandViewer 3: more flexible, interactive genomic island discovery, visualization and analysis

Overall, IslandViewer 3 represents a significant new version of this GI analysis software, with features that may make it more broadly useful for general microbial genome analysis and visualization.
