figure S4: Apple gene predictions found in the QTL interval for flavanol concentration. The figure is depicted as a set of GBrowser tracks showing the position on LG 16 (top track), close up position (second and third tracks), apple genome assembly contigs (fourth track), IASMA predicted apple gene set and apple cDNA sequences (fifth track; Malus Bioview™) [37] mapping to the region (positioned using GMAP). Gene names are indicated where known.
