Flavonoid mQTLs and flavonoid candidate gene eQTLs on pepper chromosomes. Light blue boxes indicate flavonoid mQTLs, the yellow box indicates the Ca-MYB12 transcription factor eQTL and green boxes indicate eQTLs of flavonoid structural candidate genes. Boxes with grey dotted outlines indicate flavone C-glycoside mQTLs and an FS-2 eQTL with significant LOD scores (mQTL ≥ 3.7; eQTL ≥ 3.6) at the CHI-4 locus, but these are not considered as a separate locus for those metabolites, since they overlap with the FS-2 QTL interval. CHS chalcone synthase, CHI chalcone isomerase, F3H flavanone-3-hydroxylase, FLS flavonol synthase, F3′H flavonoid-3′-hydroxylase, FS flavone synthase. (Color figure online)
