Figure 1

Ideograms depicting genome synteny of (a) Atlantic salmon ( Salmo salar ), (b) Arctic charr ( Salvelinus alpinus ), and (c) rainbow trout ( Oncorhynchus mykiss ) with three-spined stickleback ( Gasterosteus aculeatus ). Syntenic affinities with the 2R ancestral genome reconstructed by Kasahara et al. (2007)[50] are colour-coded as per the legend on the bottom right-hand corner. Synteny maps are based on the most recent published linkage maps containing information for EST accessions within each salmonid[31, 45] and the BROAD S1 stickleback genome sequence from ENSEMBL v59 - v61[60]. Salmonid linkage groups (grey) and stickleback chromosomes (red) are standardized to 100 units. Chromosomes and linkage groups are arranged in a p-arm to q-arm clockwise orientation unless otherwise noted. The positions of centromeres (black bands) on metacentric linkage groups AS-4/11/12/17/19/24/28/31/33 are undefined, as is the orientation of AS-19/28p/28q/31/33, RT-1/14p/14q/18q/26/30, and all Arctic charr linkage groups. RT-18p is not included on the reference mapping panel. Satellite marker groupings that remain unlinked to a primary linkage group segment have +2, +3 or +4 appended to their predicted linkage group affiliation. Ideograms created using Circos[63].
