Expression analysis of biosynthetic flavonoid pathway genes in cv. “Tulameen” and “Anne”. Expression of Chs. chalcone synthase; F3h. flavanone 3β-hydroxylase; Dfr, dihydroflavonol 4-reductase; Ans, anthocyanidin synthase; Ufgt UDPG-flavonoid-glycosyltransferase at fruiting stage 3 and 4 in yellow variety “Anne” and red variety “Tulameen”, respectively. The inset picture shows an example of a red and a yellow raspberry at the respective fruit ripening stages. Box plots show the mean values of the expression level with standard deviation, while dots give the sample outline.
