Functional characterization of four glycosyltransferases for biosynthesis of steroidal saponins in medicinal plant Paris polyphylla
{{output}}
Paris species are renowned for the production of important medicinal steroidal saponins (e.g., polyphyllins). UDP-dependent glycosyltransferases (UGTs) play important roles in saponin biosynthesis. However, the glycosylation steps have not been fully elucidate... ...
