Abstract

Callus culture of Chrysanthemum cinerariaefolium (Trev.) Bocc. (Asteraceae), initiated with axillary buds from the plant, have been shown to produce chrysanthemyl alcohol and chrysanthemic acid. Incubation of a cell-free homogenate from the callus with [1-14 C]-isopentenyl pyrophosphate demonstrated incorporation of radioactivity into chrysanthemyl alcohol and chrysanthemic acid as well as products from isopentenyl pyrophosphate isomerase (EC 5.3.3.2; isopentenyl diphosphate Δ3-Δ2-isomerase) and prenyltransferase activities (EC 2.5.1.11; allylic-terpene-diphosphate:isopentenyl diphosphate terpenoid-allyltransferase).

Key words

Pyrethrum - Chrysanthemum cinerariaefolium - tissue culture - chrysanthemyl alcohol - chrysanthemic acid - pyrethrins - monoterpene biosynthesis - isopentenyl pyrophosphate isomerase - prenyltransferase
