Systemic acquired resistance (SAR) is one of the intriguing issues for studying the mechanism in signal transduction system in a whole plant. We found that SAR and increase of an antifungal compound were induced rapidly and transiently in barley (Hordeum vulgare L. cv. Goseshikoku) by mechanical and biological stresses. One of the major antifungal compounds was identified as an indole alkaloid, gramine (N,N-dimethyl-3-aminomethylindole), by mass spectrum and NMR analyses. Gramine is well known as a constitutive compound of barley, but it increased significantly in the primary and secondary leaves of barley seedlings within 12 h after pruning or inoculating with the powdery mildew fungi of barley (Blumeria graminis Esp. hordei) and wheat (B. graminis Esp. tritici). However, in the leaf detached from unwounded seedlings or in the leaf inoculated with the barley powdery mildew fungus, gramine did not increase at all. In the water droplets contacted with barley leaves, the amount of leaked gramine increased dependently upon the time after the seedling was injured mechanically. We also found a tight correlation between gramine increase and enhancement of resistance to the barley powdery mildew fungus in barley leaves treated with an endogenous elicitor. Furthermore, such a systemic resistance was not observed in a barley cultivar Morex that lacks the biosynthetic pathway of gramine. From these results, we conclude that gramine is the excellent marker in rapid and transient systemic acquired resistance in barley.

Generation of hydrogen peroxide is not required for harpin-induced apoptotic cell death in tobacco BY-2 cell suspension culture

To characterize molecular and biochemical mechanisms of hypersensitive reaction (HR) in plants, a tobacco suspension culture of BY-2 was treated with the proteinaceous HR elicitor harpin from several pathovars of Pseudomonas syringae. Tobacco BY-2 cells are sensitive to harpins derived from non-pathogenic pathovars of P. syringae, such as pvs. pisi, tomato and glycinea. These three harpins induce apoptotic cell death accompanied by DNA fragmentation in BY-2. Because the cell death was also accompanied by rapid generation of hydrogen peroxide (H2O2), one of the active oxygen species, we investigated the role of H2O2 in harpin-induced cell death. Although treatment with diphenylene iodium chloride (DPI) reduced, and catalase completely abolished, the harpin-induced generation of H2O2, the frequency of cell death was not affected at all. Treatment with superoxide dismutase (SOD) enhanced the generation of H2O2, but the cell death was unaffected. These results indicate that harpin-induced apoptotic cell death does not require oxidative burst. (C) 2001 Editions scientifiques et medicales Elsevier SAS
