flavanone 3-hydroxylase, dihydroflavonol 4-reductase and flavonoid 3',5'-hydrolase are expressed in progeny with colored tuber skin, while dihydroflavonol 4-reductase and flavonoid 3',5'-hydrolase are not expressed, and flavanone 3-hydroxylase is only weakly expressed, in progeny with white tuber skin. Expression is regulated by transcription factor Stan2
Manually annotated by BRENDA team
isoform PtrDFR2 transcripts are more than twice as abundant as isoform DFR1 in young petioles and 15 times more abundant in old petioles

DFR activity is lower in YN01-429 as compared to N89-53 seed coats. Two copies of the DFR gene, which are both functional in YN01-429, homeoallelic repression or silencing, together they show very low expression levels (17fold fewer transcripts) relative to DFR acitvity in N89-53 seed coats
Manually annotated by BRENDA team
mRNA accumulation of DFR is higher in the shoots than in the leaves
