The similarity of antigenic proteins ofFusarium nivale (Fr.) Ces isolates.

The degree of similarity among dissolvable in water proteins obtained from 10Fusarium nivale isolates was studied. Tandem crossed Immunoelectrophoresis method was applied. Two immunological antisera: anti-F. nivale 4 and anti-F. nivale 15 were used in the investigation. Their homologous reactions resulted in 13 and 12 precipitation bands, respectively. The results allow to divide the isolates into three groups, according to their protein composition.
