EXPRESSION
ORGANISM
UNIPROT
LITERATURE
Ag+ increases expression of putrescine N-methyltransferase I (maximum after 48 h). The expression of PMT1 reaches the highest level at 24 h treatment in ethanol
-
dark conditions and the absence of auxin upregulate enzyme promoter activity, with light being dominant to the repressive effects of auxin. Under highly repressive conditions for alkaloid synthesis, including normal culture conditions in the light, both reactive oxygen species scavengers result in significant induction of enzyme promoter activity. Treatment of callus with catalase results in the upregulation of enzyme promoter activity
-
enzyme expression is dramatically induced by methyl jasmonate
-
high-temperature treatment induces enzyme accumulation. Overexpression of MYC2a increases nicotine biosynthesis by enhancing its binding to the promoter of the enzyme
-
isoform PMT1 expression is upregulated by methyl jasmonate in all tissues, reaching the highest level after 24 h of the treatment
isoform PMT2 expression is upregulated by methyl jasmonate in all tissues, reaching the highest level after 24 h of the treatment
the expression level of the enzyme in late vegetative growth stage samples is significantly higher compared to fruiting stage samples
-
treatments with diphenyleneiodinium chloride, Rose Bengal diacetate, and 1,2-dihydroxybenzene-3,5-disulfonic acid do not induce or repress enzyme expression
-
under normal callus growth conditions in the presence of light and auxin, enzyme promoter activity is strongly repressed
