Localization of clusters and conserved blocks in the (a) hoxb2, (b) pax6 and (c) scl datasets. For each dataset, the different orthologous intergenic sequences are shown: Rn,Rattus norvegicus; Mm, Mus musculus; Pt, Pan troglotydes; Hs, Homo sapiens; Fr, Fugu rubripes. Clusters of conserved mammalian subsequences that were subjected to motif detection (that is, clusters containing at least one subsequence per mammalian organism) are represented on the respective mammalian sequences (cluster 1 in red, cluster 2 in blue and cluster 3 in green). The conserved blocks identified using BlockSampler are represented on the Fugu intergenic sequence (in the color of the mammalian cluster it is located in). For each block the localization relative to the start of the Fugugene is given. The transcription start sites are marked with an inverse triangle.
