Abstrakt: After inoculation of Brassica juncea leaves with Alternaria brassicae, activities of the cell wall degrading enzymes, polygalacturonase (EC 3.2.1.15) and cellulase (EC 3.2.1.4) decreased in leaf blight resistant cultivar RC-781 and increased in the susceptible cultivar Varuna upto 3 d. In the leaves of both the cultivars 11 poly-peptides were observed in the absence of A. brassicae inoculation. After inoculation in the resistant cultivar RC-781 there was no change in the polypeptide pattern, while in the susceptible cultivar Varuna, four polypeptides (43.7 to 58.8 kDa) disappeared only at 3rd day after inoculation.
