Native Polyacrylamide Gel Electrophoresis carried isozyme analysis out using healthy as well as BBrmv infected sample for peroxidase (PO) and Poly Phenol Oxidase (PPO) enzyme. A single definite band of PO (Rm 0.63) was seen only in infected sample whereas thickness of the band with Rm 0.65 showed intensified production of PPO in BBrMV infected plants.
