Retrogenes in S. japonica. a Schematic alignments of Ectocarpus sp. intron-rich sex-chromosome genes (top) and intronless, autosomal orthologs in S. japonica (bottom). Genes that are located on the Ectocarpus sp. SDR are highlighted in bold. Exons, dark blue; UTRs, light blue; introns, dotted lines (introns are not shown to scale). b Expression of S. japonica intronless retrogenes whose orthologs in Ectocarpus sp. are either located on the sex chromosome (Sex-chromosome-derived) or autosomal (Autosome-derived)
