From RAPD fingerprints, the example of RAPD banding patterns are shown in Figure 1. The RAPD profiles showed substantial differences between the control and the treated plants with apparent changes (disappearance and/or appearance) in the number of DNA bands produced by each primer. The GTS values ranged from 52.3 to 91.1% (Table 1). At the highest concentration of Cd supplemented (120 mg/kg), the DNA resulted in the highest changes (GTS = 52.3%). The results indicate that the GTS value in I. aquatica was affected by Cd exposure. These results correlated with previous data suggested that Cd could induce DNA changes in plant species
