Abstract: 
The growth of the wheat stem rust (Puccinia graminis f.sp. tritici, race 32) on the resistant wheat cv. Feldkrone is restricted by cell necrosis. Those epidermal cells first invaded react hypersensitively as is shown by the appearance of autofluorescence and the formation of lignin in the invaded cells. Cell necrosis was inhibited by soybean agglutinin (SBA), a lectin, which reacts specifically with galactose and N-acetyl-galactosamine, by E. corallodendron lectin (ECO), specific for galactose, as well as by galactose oxidase, an enzyme which acts on the non-reducing terminal D-galactosyl and N-acetyl-D-galactosaminyl residues of surface galactoconjugates. As a result of this inhibition of cell necrosis, the size of the rust colony on treeted leaves increased, i.e. the resistance of the wheat was lowered. Since previous results had shown that SBA binds to galactolipis ont he surface of wheat protoplasts, SBA, ECO and galactose oxidase apparently interfere with the interaction of host plasmalemma with the fungal haustorium wall during the initial stages of infection.
