I. Mechnikov's National University popup.description2 The electrophoretical spectrum of multiple molecular forms of peroxi-dase, superoxide dismutase, phenol oxidase, cytochrome oxidase, ascorbite oxidase were studied in the tissues of the eight Fusarium strains, inshoots and leaves of the eleven lines winter wheat with different resistance to fusarium head blight, in shoots of fifteen wheat varieties (resistant, sensitive and tolerant as selectionists assess) The high pathogenic Fusarium strains have less electrophoretical en-zyme bands on the electrophoregrammes, than nonpathogemc ones All investigated wheat genotypes have resembling structure of oxidoreduc-tase isozymes Expression of some isoforms, particularly superoxid dismutase, phenol oxidase, peroxidase correlates with the plant resistance level to Fusanum Fusarium infection of the plants on early and late ontogenesis (germination and wheat-ear formation) leads to increasing expression of the large majority of multiple molecular forms This increase is more considerable in Fusarium head blight resistance wheat varieties The reaction of the sensitive genotypes is very weak or entirely absent So, expression of the investigated enzyme isoforms correlates with Fusarium head bhghr resistance level of winter wheat plants and it can be use in plant breeding Product Description popup.authors popup.nrat_date 2020-04-02 Close
