Characterization of glycosyltransferases responsible for salidroside biosynthesis in Rhodiola sachalinensis

► UGT72B14 has an important function in salidoroside synthesis. ► UGT73B6 contribute to salidoroside synthesis. ► UGT74R1 does not participate in salidroside synthesis. ► A transformed hairy root system is suitable for salidroside production.
