High cytokinin levels induce a hypersensitive-like response in tobacco.

Popis výsledku v původním jazyce

Background and Aims Cytokinins are positive regulators of shoot development. However, it has previously been demonstrated that efficient activation of the cytokinin biosynthesis gene ipt can cause necrotic lesions and wilting in tobacco leaves. Some plant pathogens reportedly use their ability to produce cytokinins in disease development. In response to pathogen attacks, plants can trigger a hypersensitive response that rapidly kills cells near the infection site, depriving the pathogen of nutrients andpreventing its spread. In this study, a diverse set of processes that link ipt activation to necrotic lesion formationwere investigated in order to evaluate the potential of cytokinins as signals and/or mediators in plant defence against pathogens. KeyResults Plants can produce sufficiently high levels of cytokinins to trigger fast cell death without any intervening chlorosis - a hallmark of the hypersensitive response. The results suggest that chloroplastic hydrogen peroxide orchestra
