A conifer UDP-sugar dependent glycosyltransferase contributes to acetophenone metabolism and defense against insects

Abstract:

Acetophenones are phenolic compounds involved in the resistance of white spruce (Picea glauca) against spruce budworm (Choristoneura fumiferiana), a major forest pest in North America. The acetophenones pungenol and piceol commonly accumulate in spruce foliage in the form of the corresponding glycosides, pungenin and picein. These glycosides appear to be inactive against the insect but can be cleaved by a spruce β-glucosidase, PgβGLU-1, which releases the active aglycons. The reverse glycosyl...
