Abstract
Using the recently isolated cDNA clone LOX2: Hv : I which codes for the most abundant jasmonate-inducible lipoxygenase (LOX) in barley leaves (Voros et al., 1998), we analysed the capability of different activators of systemic activated resistance (SAR) to induce the expression of that LOX. Upon treatment of barley leaves with salicylate, 2,6-dichloroisonicotinic acid and benzo-(1,2,3)-thiadiazole-7-carbothioic acid S-methyl ester, all these compounds were able to induce the expression of the LOX2: Hv : I gene, whereas upon infection with the powdery mildew fungus (Blumeria graminis f sp. hordei) mRNA accumulation was not detectable in compatible or in incompatible interactions. The induction of the LOX2: Hv : I protein by SAR activators and the expression of different sets of genes induced by jasmonate and salicylate, respectively, are discussed in relation to defense responses against pathogenic fungi.
