[Conjugation resistance to Fusarium graminearum Schwabe with multiple molecular forms of some enzymes in winter...

Electrophoretic spectra of multiple molecular forms of peroxidase (EC 1.11.1.7), superoxide dismutase (EC 1.15.1.1), phenol oxidase (EC 1.10.3.1), and cytochrome oxidase (EC 1.9.3.1) in seedlings of two aegilops species and eleven genotypes of bread winter wheat differing in the level of their resistance to Fusarium infection are presented. Several izoforms of peroxidase, phenol oxidase, and superoxide dismutase correlate with the level of resistance to Fusarium. Infection of plants with the pathogen enhances expressiveness of some multiple forms of enzymes. Such response to infection in less pronounced in the sensitive genotypes as compared with that in the resistant ones.
