The protein patterns from germinated mildew conidia are characteristic for the isolates (AL-1, RU-3 and OR-7) obtained after two-dimensional electrophoresis. The activity of beta-1,4-glucanase in barley leaves after infection increased possibly due to an elicitor activity of a beta-1,4-glucane released from the fungus or the plant cell wall. This was not correlated with the resistance gene. Barley plants infected with mildew show more proteins than healthy plants, they are related to the infection but they did not mirror the respective mildew isolate. The number of proteins or glycoproteins in samples of barley leaf extracts decreases - compared with the original leaf extract - when mixed with the mildew conidia extracts due to an interaction of components. The glycoprotein pattern in a barley line without resistance genes shows more spots than that of the line with the resistance gene
