Phylogenetic exploration of bacterial genomic rearrangements.

UNLABELLED: We present a graphical tool dedicated to the exploration of bacterial genome rearrangements. The principle of this exploration relies on the reconstruction of ancestral genomes at each internal node of a gene-order-based phylogenetic tree. This tool allows the selection of internal nodes to visualize the rearrangements between the inferred chromosome of this node and its direct descendant on the tree. AVAILABILITY: PEGR is available at the Genopole Toulouse Bioinformatics platform.
