EXPRESSION
ORGANISM
UNIPROT
LITERATURE
enzyme expression is induced correspondingly by exogenous elicitors including gibberellic acid (about 2.5fold increased expression at 1 mg/l) and sucrose (about 5fold increased expression at 120 g/l)
-
enzyme gene expression is detected only after the beginning of coloring stage or yellow stage, and is highest in the red pericarps
-
ethylene better stimulates expression of the ufgt promoter in the dark than under light
-
high C/N ratios in the growth media enhance the enzyme expression
the enzyme is expressed not only at the sites of anthocyanin biosynthesis, but also at sites of flavonol glycoside biosynthesis
transcriptional activity is higher expressed in the red color of Phalaenopsis cultivars than in the white cultivars. In the red labellum of Phalaenopsis, the enzyme also shows higher expression levels than that in the white perianth
-
treatment of grape berries with 1-methylcyclopropene inhibits ufgt mRNA accumulation
-
while there is little enzyme expression before veraison, these transcripts begin to accumulate at week 8 and 10 after flowering to reach maximal levels at week 12 after flowering and decreases thereafter
