LITERATURE
anthocyanin levels shows a positive correlation with the expression of dihydroflavonol 4-reductase
anthocyanin levels shows a positive correlation with the expression of dihydroflavonol 4-reductase. Down-regulation of dihydroflavonol 4-reductase expression results in fading leaf color
decrease at stage of pigmentation inititation
ectopic expression of a heterologous flavonol synthase gene leads to the significant down-regulation of endogenous Nicotiana tabacum dihydroflavonol-4-reductase expression in genetically transformed tobacco lines, and promotes Nicotiana tabacum flavonol synthase expression albeit weakly. Conversely, the overexpression of introduced dihydroflavonol-4-reductase genes suppresses the expression of Nicotiana tabacum flavonol synthase and promotes the expression of Nicotiana tabacum dihydroflavonol-4-reductase
expression is down-regulated in response to drought stress and abscisic acid, and unaffected by gibberellic acid treatment
expression is induced by methyl jasmonate, cold, H202 and heat irradiation
expression is up-regulated in response to wounding, with concomitant modulation of catechins content
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

GbDFR1 expression is induced by UVB radiation, abscisic acid, 5-aminolevulinic acid, and ethephon
GbDFR1 expression is suppressed by salicylic acid
GbDFR2 expression is induced by UVB radiation, abscisic acid, ethephon, and salicylic acid , and highly induced by wounding
in response to drought stress
in response to wounding, with concomitant modulation of catechins content. Expression is maximum in younger rather than older leaves

induction of gene BrDFR2 by cold stress dependent on the genotypes, overview
induction of gene BrDFR3 by cold stress dependent on the genotypes, overview
induction of gene BrDFR4 by cold stress dependent on the genotypes, overview
induction of gene BrDFR5 by cold stress dependent on the genotypes, overview

induction of gene BrDFR8 by cold stress dependent on the genotypes, overview
induction of gene BrDFR9 by cold stress dependent on the genotypes, overview
low-dose UV treatment, and 5-aminolevulinic acid, and salicylic acid have no obvious induction effect on GbDFR3
no effect on GbDFR2 expression by 5-aminolevulinic acid
the abundance of endogenous McDFR transcripts is greatly reduced in TRV-McDFR infected leaves
the GbDFR3 expression is downregulated by abscisic acid
the GbDFR3 expression is induced by wounding and ethephon
transcript level is significantly higher in red form of the plant than in the green form of plants

wounding has no effect on GbDFR1 expression
