LITERATURE
a progressive increase in activity of anthocyanidin synthase is observed in purple fruits from 7 to 21 days after anthesis
activity of anthocyanidin synthase in leaves of all genotypes and fruits of green and white colour progressively decreases from 7 to 21 days after anthesis
decrease at stage of flowering
expression is strongly increased under salt stress
FcANS1 expression is responsive to light, as bagging the syconia reduced FcANS1 expression and anthocyanin content in bothfig skin and female flowers compared to natural light conditions
-
FcANS1 expression is significantly upregulated during syconia maturation. Transcript expression of FcANS1 in the fruit peel and female flowers differs between the bagging treatment and the natural lighting controls. FcANS1 transcripts are more abundant in the control samples
-
reduced transcription of the ANS gene caused by mutations in a cis-acting element is likely to result in the pink trait in onions
the expression of RnANS1 (Ribes nigrum anthocyanidin synthase 1) is upregulated during fruit maturation, and correlated with the accumulation of anthocyanins and soluble carbohydrates in the fruit
transcript abundance of ANS correlates closely with petal pigmentation levels, and variation in the expression levels of ANS is a key determinant of differences in organ color between crabapple cultivars
