decrease at stage of pigmentation inititation
expression is down-regulated in response to drought stress and abscisic acid, and unaffected by gibberellic acid treatment

expression is down-regulated in response to drought stress and abscisic acid, and unaffected by gibberellic acid treatment; in response to drought stress
expression is up-regulated in response to wounding, with concomitant modulation of catechins content

expression is up-regulated in response to wounding, with concomitant modulation of catechins content; in response to wounding, with concomitant modulation of catechins content. Expression is maximum in younger rather than older leaves
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; GbDFR2 expression is induced by UVB radiation, abscisic acid, ethephon, and salicylic acid , and highly induced by wounding; the GbDFR3 expression is induced by wounding and ethephon
GbDFR1 expression is suppressed by salicylic acid; the GbDFR3 expression is downregulated by abscisic acid
induction of gene BrDFR10 by cold stress dependent on the genotypes, overview; 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 BrDFR6 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; wounding has no effect on GbDFR1 expression
the abundance of endogenous McDFR transcripts is greatly reduced in TRV-McDFR infected leaves
