Partial characterization of cytosolic superoxide dismutase activity in the interaction of meloidogyne incognita with two cultivars of glycines max

Abstract

Superoxide dismutase (SOD) was identified in the root knot nematode, Meloidogyne incognita by gel electrophoresis. A band with SOD activity present in the nematodes was common to both the nematode and soybean (Glycines max). The soybean cultivars had two bands with SOD activity that were not detected in the nematode. The preparasitic second stage juveniles contained a band with SOD activity that was unique, but this band was not detected in the parasitic stages nor in parasitized root tissue. The SOD activity in root knot nematodes changed qualitatively and quantitatively as the nematodes matured as determined in IEF (iso-electric focusing) gels stained with nitro blue tetrazolium. This suggests that increases in SOD activity detected in plant root tissue parasitized by root knot nematodes may be of nematode and/or plant origin.
