this induced defensive response ( hyperoleoresinosis ) is the result of a transient rise in the ability to biosynthesize cyclic monoterpenes and diterpene resin acids as measured by the in vivo incorporation of label from [ u- ( 14 ) c ] sucrose relative to untreated controls , and is accompanied by a corresponding rise in the levels or activities of the relevant terpene cyclases as determined by in vitro assay using labeled acyclic precursors .
