Two strains of Agrobacterium rhizogenes (15834, LBA 9402) and one Agrobacterium tumefaciens strain [GV 3101 (PMP90RK, p35SGUS-2)] and four culture media were tested and compared for their ability to induce hairy root formation on wounded Papaver somniferum L. hypocotyls. Five weeks after the infection with A. rhizogenes LBA 9402, hairy roots appeared on 80% of the hypocotyls maintained in the hormone-free liquid medium. Six hairy-root cultures were established. Transformation was confirmed by polymerase chain reaction analysis. One clone was analysed for its alkaloid production. The total alkaloid content was higher in the transformed roots (0.46±0.06% DW) than in the untransformed roots (0.32±0.05% DW). The transformed roots accumulated three times more codeine (0.18±0.02% DW) than intact roots (0.05±0% DW). Moreover, morphine (0.255±0.03% DW) and sanguinarine (0.014±0% DW) were found in the liquid culture medium.
