| Production and Release of Isoflavonoids by Lupin Cell Cultures  | | | Abstract
| Cell cultures derived from white lupin (Lupinus albus) radicles consist o f a mixture o f friable cell aggregates and finely divided cells. Both types o f tissue accumulate two isoflavonoid aglu-cones, genistein and 2'-hydroxygenistein, their 7-O-glucosides, and their respective 6-, 8-, and 3'-monoprenyl-, as well as the 6,3'-diprenyl derivatives. M ost o f these metabolites are differen tially released in the culture medium. The relative am ounts o f aglucones, glucosides and preny-lated derivatives that are produced by the aggregates and cells, as well as those excreted into the medium, are discussed in relation to culture growth. | | |

| Plant Metabolism of Xenobiotics. Comparison of the Metabolism of 3.4-Dichloroaniline in Soybean Excised Leaves and Soybean Cell Suspension Cultures  | | | Abstract
| Excised leaves and cell suspension cultures of soybean (Glycine m ax L.) were incubated with [UL-14C]-3,4-dichloroaniline. The compound was almost completely metabolized after 48 h in both systems; it was apparent that the major detoxification pathways present in the excised leaves were also present in the cultured cells. Besides considerable amounts of insoluble resi dues, the N-glucosyl and the N-malonyl conjugates of 3,4-dichloroaniline, and a yet unknown metabolite was formed in the excised leaves; tentatively the latter was identified with the 6'-0-malonylester of N-glucosyl-3,4-dichloroaniline. The cell suspension cultures produced predominantly the N-malonyl conjugate, besides negligible amounts of the N-glucosyl conju gate, and insoluble residues; the majority of the N-malonyl compound was excreted into the medium. It was shown, that the metabolism of 3,4-dichloroaniline in excised leaves and cell suspension cultures of soybean was directed towards different end products: the excised leaves were able to make extensive use of cell wall structures as a deposit for xenobiotic bound resi dues, resembling plants in this respect; lack of these structures in the cultured soybean cells resulted in a soluble end product, namely the N-malonyl conjugate. | | |
