Abstract: | The content of wheat germ agglutinin (WGA) in hydrogen peroxide-treated seedlings was studied by indirect competitive enzyme-linked immunosorbent assay. WGA content in roots showed a transitory increase: at 10 mM hydrogen peroxide, the maximum level was observed after 2 h; at 1 mM hydrogen peroxide, the maximum occurred 2 or 24 h after treatment. Lectin induction by hydrogen peroxide is viewed as an element of a feedback mechanism limiting the operation of defense responses during pathogenetic processes. |
