UNIPROT
LITERATURE
exposure of plants to enhanced UV-B radiation induced the UGT84A-encoding genes and leads to a transient increase in sinapoylglucose and sinapoylmalate concentrations, compared to the wild type, crude protein extracts from leaves of UGT84A1 overexpression plants displayed increased activity toward 4-coumarate and ferulate, the preferred in vitro substrates, the overexpressing line UGT84A1 exhibits increased levels of sinapoylglucose in seeds and seedlings, the seed sinapine content is slightly increased in UGT84A1, overexpression of UGT84A1 results in a significant increase of cell wall-bound sinapate
exposure of plants to enhanced UV-B radiation induced the UGT84A-encoding genes and leads to a transient increase in sinapoylglucose and sinapoylmalate concentrations, leaves of UGT84A3 overexpression displayed a significantly higher capacity to synthesize feruloylglucose, the overexpressing line UGT84A3 exhibits increased levels of sinapoylglucose in seeds and seedlings, the seed sinapine content is slightly increased in UGT84A3, analysis of liberated from cell walls reveals for UGT84A3 a significant increase in cell wall-associated 4-coumarate, ferulate and sinapate
exposure of plants to enhanced UV-B radiation induced the UGT84A-encoding genes and leads to a transient increase in sinapoylglucose and sinapoylmalate concentrations, overexpression plants did not display changes in UGT specificity of leave extracts, the overexpressing line UGT84A4 exhibits increased levels of sinapoylglucose in seeds and seedlings, the seed sinapine content is slightly increased
exposure of plants to enhanced UV-B radiation induced the UGT84A-encoding genes and leads to a transient increase in sinapoylglucose and sinapoylmalate concentrations, UGT84A2 overexpression caused increasing activity toward sinapate, the overexpressing line UGT84A2 exhibits increased levels of sinapoylglucose in seeds and seedlings, the seed sinapine content is slightly increased in UGT84A2, mature leaves of UGT84A2 show a slight increase in the sinapoylmalate content, overexpression of UGT84A2 results in a significant increase of cell wall-bound sinapate
given the impact of UGT84A3 overexpression on the amount of cell wall-associated hydroxycinnamates, analysis of the cell wall fraction of the insertion knock-out mutant UGT84A3 shows a significant decrease of the 4-coumarate content in cell walls of null mutant whereas the levels of ferulate and sinapate are not changed compared to the wild type
