Summary of the differential protein expression in P. cyrtonema rhizomes grown in different cadmium concentrations. a Number of up/down regulated proteins in cadmium treated (D2-D5) rhizomes as compared to D1. b Venn diagram showing number of common and specific proteins that were differentially expressed in rhizomes grown in different cadmium concentrations. Where D1 = 0.5 mg/kg (CK), D2 = 1 mg/kg, D3 = 2 mg/kg, D4 = 4 mg/kg, and D5 = 8 mg/kg
