Abstract
Barley (Hordeum vulgare) seedlings were inoculated with the biotrophic pathogen Erysiphe graminis f. sp. hordei, the biotrophic nonhost path ogen E. graminis f. sp. tritici, and the necrotrophic nonhost pathogen Pseudomonas syringae pv, syringae. The levels of free salicylic acid and of salicylic-acid conjugates remained low after infection with E. graminis f. sp, hordei or E. graminis f. sp. tritici while they increa sed after inoculation with P, syringae pv. syringae. Pathogenesis-rela ted proteins PR1, PR3 (chitinase), PR5 (thaumatin-like), and PR9 (pero xidase) accumulated after inoculation with all three pathogens.
