SummaryThe transformed roots of Campanula glomerata L. var. dahurica Fish., induced by infection with Agrobacterium rhizogenes MAFF 03-01724, produced the anthocyanins cyanidin 3-glucoside and cyanidin 3-rutinoside, a flavonoid rutin and a phenylpropanoid glucoside coniferin, together with the polyacetylene constituents lobetyol, lobetyolin and lobetyolinin. Although illumination was inhibiting for root proliferation, it was an essential factor for the accumulation of anthocyanin and flavonoid in the tissues. Addition of benzyladenine (BA) to the medium also promoted the accumulation of phenolics (anthocyanins, rutin and coniferin) in the roots. Polyacetylene production in the roots was not greatly affected by either illumination or BA treatment.
