Soybean agglutinin, a lectin specific for N-acetyl-d-galactosamine and d-galactose, was previously shown to agglutinate wheat leaf protoplasts (Larkin 1978 Plant Physiol 61: 626-629). We investigated the receptors for soybean agglutinin on the plasma membrane of these protoplasts. After treatment of the protoplasts with galactose oxidase, they were no(More)
When highly resistant wheat (Triticum aestivum L.) varieties are infected by an avirulent race of the stem rust fungus (Puccinia graminis Pers. f. sp. tritici Erics. and E. Henn.), penetrated host cells undergo rapid necrotization. This hypersensitive cell death is correlated with cellular lignification which efficiently restricts further fungal growth.(More)
We have recently reported the isolation and characterization of a glycoprotein (Mr 67 000) from germ-tube walls of Puccinia graminis f. sp. tritici which elicits the cellular hypersensitive lignification response in wheat (G. Kogel et al., 1988, Physiol. Mol. Plant Pathol. 33, 173–185). The present study uses this glycoprotein, referred to as Pgt elicitor,(More)
The growth of the wheat stem rust (Puccinia graminis f.sp. tritici, race 32) on the resistant wheat cultivar 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 soy-bean(More)
Immunoelectron microscopy (IEM) was used to analyze the compatible and incompatible host-pathogen interaction between the obligate, biotroph stem rust (Puccinia graminis f.sp. tritici; Pgt) and primary leaves of wheat (Triticum aestivum L.). The investigation was focused on the subcellular localization of a fungal elicitor glycoprotein of stem rust(More)
Rusted wheat leaves were incubated simultaneously with alanine-1-14C and glucose-6-T. Uredospores formed during the application of the tracers were collected and the bound alanine was isolated from the spores and the host tissue. Comparison of the 14C/T ratio of spore-alanine and host-alanine indicates that the mycelium not only withdraws alanine from the(More)
