The effect of camptothecin (CPT) on the growth of maize cultured cells. (A) An initially similar number of maize cells (3.3 ± 0.5 mg) were grown on MS medium supplemented with DMSO (Control, CON) or with different concentrations of CPT during 30 days. The difference in fresh weight between day 0 and day 30 is shown. (B) Maize cells were grown on MS medium supplemented with DMSO (black bars) or with 0.5 μM CPT (white bars) throughout different number of days. The difference in fresh weight between day 0 and the indicated day is represented. The graphics depict the average of three independent experiments, and error bars (SE) are annotated.
