DcH3.3 and DcNAC1 Regulate the Expression of UGT73A93 Involved in the Changes in Flower Colour and Fungal Resistance in Carnation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Carnation (Dianthus caryophyllus) contains abundant flavonoid glycosides (FGs), which are important natural functional and colour components. However, there are few reports on the modification of UDP‐glycosyltransferases (UGTs) in relation to flavonoids in carnation.

Identifying 6,7,4′-Trihydroxyisoflavone as a Potent Tyrosinase Inhibitor

Bioscience, Biotechnology, and Biochemistry, 2005
A known biotransformed compound, 6,7,4'-trihydroxyisoflavone, was identified as a potent tyrosinase inhibitor. It inhibited mushroom tyrosinase with an IC50 value of 9.2 microM, which is six times the anti-tyrosinase activity of kojic acid (IC50 = 54.4 microM).
