Abstract:
Two wild soybean lines and two cultivated soybean varieties with different resistance to soybean mosaic virus were infected with SMV strain N3, and the activities of L-phenylalaninammo-nialyase (PAL), Peroxidase (POD) and Superoxide Dismutase (SOD) in leaves were assayed and the differences of resistance in two subspecies were compared. The results indicated that the activities of defense enzymes in the resistant soybean variety were higher than that of the control, and the susceptible variety was in reverse. The change of enzymes activity was similar, but which in cultivated soybean was faster than that in wild soybean. The defense pathway between wounding and virus invasion was partly overlapping, but the mechanism varied a lot.
