Callus and hairy root cultures of Linum leonii were established. The genetic transformation in hairy roots was proven by PCR analysis, which showed integration of rol A and rol C genes into the plant genome. Calli and hairy roots accumulate the arylnaphthalene lignan justicidin B as a major constituent. Hairy roots produce 5-fold higher yields of justicidin B (10.8 mg g(-1) DW) compared to calli. Justicidin B shows strong cytotoxicity on the chronic myeloid leukemia LAMA-8 and K-562 cell lines and on the chronic lymphoid leukemia SKW-3 cell line with IC(50) values of 1.11, 6.08, and 1.62 microM, respectively. Apoptotic properties of justicidin B are reported for the first time.
