Description	Preparations with elicitation activity were obtained from the mycelium of Leptosphaeria maculans, a fungal pathogen of oilseed rape (Brassica napus). Crude delipidated and deproteinized extract from fungal cell walls induced expression of pathogenesis related gene 1 (PR1), hydrogen peroxide accumulation, and enhanced resistance of B. napus plants toward infection by L. maculans. Elicitation activity significantly decreased after treatment of a crude extract with glucanase. Monosaccharide composition analysis of a crude extract purified by ion-exchange chromatography revealed glucose (similar to 58 mol %), mannose (similar to 22 mol %), and galactose (similar to18 mol %) as the major sugars. FT-IR and NMR spectra confirmed the presence of both carbohydrate and polypeptide components in the purified product. Correlation NMR experiments defined trisaccharide bound to O-3 of serine residue alpha-D-Glcp-(1-2)-beta-D-Galf-(1-6)-alpha-D-Manp-(1-3)-L-Ser. Terminal alpha-D-Glcp and (1-6)-beta-Dglucan were also detected. The obtained results strongly support the conclusion that these carbohydrates induce defense response in Brassica napus plants.
