Fig. 2: Chromosomal distribution of metabolic QTLs identified in this study.

QTL regions (represented by the confidence interval) across the C. clementina genome are responsible for metabolite levels from mature pericarp, mature pulp, old leaves and young leaves. The x axis indicates genetic positions across the C. clementina genome in cM. The heat map under the x axis illustrates the density of metabolic QTLs across the genome. The window size is 10 cM. The y axis indicates every flavonoid trait detected in the four tissues. The heat map shown in red on the right illustrates LOD values for each trait
