Abstract
Tissue cultures ofChrysanthemum cinerariaefolium were established, and then used to study the production of pyrethrin insecticides, and their precursor chrysanthemic acid. Callus cultures and root-differentiated cultures did not contain pyrethrins whereas shoot differentiated callus was found to produce the pyrethrins. Chrysanthemic acid was isolated by extraction from callus cultures, and feeding14C-labelled chrysanthemic acid to a cell suspension ofC. cinerariaefolium established that the acid accumulates largely as a glucoside ester.
