Changes in the soluble protein pattern of leaves of eight lines of barley, carrying different resistance genes to mildew, were analysed by SDS‐polyacrylamide gel electrophoresis and isoelectric focusing. Apparently new host proteins were induced by Erysiphe graminis f. sp. hordei in the incompatible reaction which were not present in the immune or susceptible response. These proteins are of low molecular weight, 13,500–27,500 d, and have either very low or very high isoelectric points. Thus, they resemble the pathogenesis‐related proteins found in many dicotyledonous species.
