摘要: Inoculation of one leaf cucumber, muskmelon or watermelon with Colletotrichum lagenarium induces a systemic increase in soluble peroxidase activity. Increased total activity is reflected an intercellular wash fluids tissue. The specific extracted from systemically induced leaves was at least two-fold higher than control leaves. Intercellular migrates as cluster three bands on high pH native polyacrylamide gels, and the patterns are similar for watermelon. peroxidases c. 30 kD determined by SDS gel electrophoresis. Antibodies raised against cucumber reacted partial identity Ouchterloney double diffusion assay.
