IslandPathversion 1.0

An aid to the identification of genomics islands, including pathogenicity islands, of potentially horizontally transferred genes

See the help file for more information, plus analyses that illustrate the utility of IslandPath.

Select the islandbuttombutton below for a given organism to view a graphical representation of the organism's genome with some features commonly associated with genomic islands marked. These features include abnormal %G+C, dinucleotide bias, proximity to tRNA and other structural RNA and the presence of mobility genes (transposases and integrases). Plain text tables of the ORF %G+C data and ORF-cluster dinucleotide bias data are also available by request. A cautionary note: This analysis does not definitely identify islands of horizontally transferred genes, but rather should be considered a guide for the identification of clusters of genes that are more likely to have horizontal origins. A reminder that such analysis only identifies a subset of potential recent horizontal transfers (i.e. those that involve genetic exchange between organisms of differing DNA signatures). See the publication associated with IslandPath for further information (William Hsiao, Ivan Wan, Steven J. Jones, and Fiona S.L. Brinkman, Bioinformatics, Feb 2003 PMID:12584130). We thank the National Centre for Biotechnology Information (NCBI), particularly Tatiana Tatusov, for providing helpful files for IslandPath and acknowledge the efforts of the many microbial and other genome projects that have made such an analysis possible.

IslandPath is maintained by William Hsiao of the Brinkman Laboratory at Simon Fraser University, BC, Canada. Email islandpath-mail@sfu.ca with any questions/comments. If you wish to be notified of changes to islandpath, you can subscribe to the islandpath-update mailing list by sending an email to maillist@sfu.ca with "subscribe islandpath-update" in the subject or body of the message.

The tables below list organisms alphabetically. You may also view this data according to a measure of %G+C variance in the genome. The gene G+C variance for a bacterial genome appears to reflect the number of incidences of recent horizontal gene exchange with organisms of differing G+C ratios, for extreme cases.
