Pyrenophora graminea is a seed-borne pathogen and is the causal agent of the barley leaf stripe disease. In order to better understand this disease and its genetic interactions with barley, SDS-PAGE electrophoresis, hordein patterns (groups D, C and B) of five barley cultivars inoculated with selected isolates were investigated. Results showed the absence of particular hordein subunits and the degradation of others in most of the cultivars inoculated with virulent isolates. However, a complex interaction pattern was realized between isolates × cultivars with variable virulence and resistance levels respectively. Identical numbers of polymorphic bands were observed through the different assays (for each isolate/cultivar).

Moreover, since single seed tests showed no differences in the hordeins profiles of the non-infected seeds, we presumed that the changes in the hordeins profiles of the infected seeds were due to the infection with P. graminea. The protein profiles were highly repeatable. This reproducibility is encouraging further analysis to identify protein complexes that might contain host defense proteins and pathogenicity factors.
