Fig. 4

Circular ideogram showing locations of synteny mapped transcripts and QTLs. Black rectangles represent southern flounder linkage groups. The location of QTLs identified in Japanese flounder are indicated by red (QTL for resistance to lymphocystis [30]), orange (QTL for resistance to Edwardsiella tarda [31]), and yellow (QTLs for growth; qWi-f14–1, qWi-f14–2 and qWe-f14, [64]).Genes identified as being significantly up- or down-regulated in European flounder when exposed to pollutants [33] are represented in blue inside the circle; genes identified as being differentially expressed in the context of salinity differences [32] are indicated in green outside the circle. Relative height of bars represents number of transcripts mapped to a single location
