The document describes the PHRINGE Synteny tool, which allows users to visualize synteny between oomycete genomes. The tool displays genomic regions from a source species and highlights regions of conserved gene order and orthologs in target species. Users can mouse over genes for more information or click genes to link to detailed records. The tool is useful for tracking genes like virulence effectors that may not be syntenic across species due to genomic rearrangements.
