| Description
| - The role of nitric oxide in the pathogenesis of Oidium neolycopersici was studied on leaf discs of three Solanum spp. genotypes differing in their susceptibility to powdery mildew infection. The germination of pathogen conidia, development of infection structures and reaction of host tissues were compared for S. lycopersicum (susceptible), S. chmielewskii (moderately resistant) and S. habrochaites f. glabratum (highly resistant genotype) in presence of compounds modulating NO levels. The effect of NO donor sodium nitroprusside varied among genotypes and studied time intervals whereas NO scavenger 2-phenyl- 4,4,5,5,-tetramethylimidazoline-1-oxyl 3-oxide accelerated fungal development in all three Solanum spp. genotypes. The exposure of leaf discs to NOS inhibitor NG-nitro-l-arginine methyl ester decreased powdery mildew growth namely in S. chmielewskii. Confocal laser scanning microscopy using the fluorescent probe 4-amino-5-(N-methylamino)-2,7-difluorofluorescein diacetate localised NO accumulation both in pathogen germ tubes and appressoria and in penetrated cells of resistant genotypes of S. chmielewskii and S. habrochaites f. glabratum. Our results confirm an essential role for NO in powdery mildew pathogenesis including the penetration of biotrophic pathogen and the initiation of hypersensitive reaction, and suggest the contribution of NO to molecular mechanisms of diversity in interactions of Solanum spp. with O. neolycopersici.
