Název v původním jazyce

Local and systemic production of nitric oxide in tomato responses to powdery mildew infection

Popis výsledku v původním jazyce

This article reports the changes in nitric oxide (NO) production in L. esculentum cv. Amateur, L. chmielewskii and L. hirsutum f. glabratum. A specific, two-phase increase in NO production was observed in the extracts of infected leaves of moderately andhighly resistant genotypes. Moreover, transmission of a systemic response throughout the plant was observed as an increase in NO production within tissues of uninoculated leaves. The results suggest that arginine-dependent enzyme activity was probably the main source of NO in tomato tissues, which was inhibited by competitive reversible and irreversible inhibitors of animal NO synthase, but not by a plant nitrate reductase inhibitor. In resistant tomato genotypes, increased NO production was localizedin infected tissues by confocal laser scanning microscopy. NO production observed in the extracts from pathogen conidia, together with elevated NO production localized in developing pathogen hyphae, demonstrates a complex role of NO in pl
