Mycosphaerella graminicola (Zymoseptoria tritici commonly known as Septoria), the causal agent of Septoria Leaf Blotch (STB), is considered one of the major threats to European wheat production. Previous studies have shown the importance of ubiquitination in plant defence against a multitude of pathogens. However the ubiquitination machinery in wheat is under studied, particularly E2 enzymes th...

septoria tritici blotch (stb), caused by mycosphaerella graminicola (anamorph: septoria tritici), is one of the most important diseases of wheat worldwide that has been intensified recently in some regions of iran including moghan plain. in this study reaction of 23 bread and durum wheat cultivars to 10 isolates of the pathogen collected from moghan region during 2007 and 2008, were evaluated u...

Northern areas of the western United States are one of the most productive wheat growing regions in the United States. Increasing productivity through breeding is hindered by several biotic stresses which slow and constrain targeted yield improvement. In order to understand genetic variation for stripe rust (Puccinia striiformis f. sp. tritici), Septoria tritici blotch (Mycosphaerella graminico...

The disease septoria leaf blotch of wheat, caused by fungal pathogen Septoria tritici, is of worldwide concern. The fungus exhibits a hemibiotrophic lifestyle, with a long symptomless, biotrophic phase followed by a sudden transition to necrotrophy associated with host necrosis. Little is known about the systematic interaction between fungal pathogenicity and host responses at specific growth s...

Zymoseptoria tritici, the causal agent of septoria tritici blotch, a serious foliar disease of wheat, is a necrotrophic pathogen that undergoes a long latent period. Emergence of insensitivity to fungicides, and pesticide reduction policies, mean there is a pressing need to understand septoria and control it through greater varietal resistance. Stb6 and Stb15, the most common qualitative resist...

Im Rahmen dieser Studie soll eine Nahsensorikmethode zur Identifizierung und Quantifizierung von Pflanzenkrankheiten entwickelt werden. Die Komplexität verschiedener Pathogene einbeziehend, soll der Einfluss der Schaderreger Erysiphe graminis (Echter Mehltau) und Septoria tritici (Blattdürre) als Vertreter zweier unterschiedlicher Erregerklassen auf die Reflexion von Weizenpflanzen untersucht w...

This is a morphocultural study under in vitro and in vivo condition on some Septoria tritici variants mainly originated from isolates collected from cultivars bearing Bobwhite 'S' and Kavkaz germplasm. The objective was to show the variability in cultural and morphobiometrical characters of atypical isolates (variants) derived from these germplasms and discuss the relationship with the pathogen...

Crops are attacked by many potential pathogens with differing life-history traits, which raises the question of whether or not the outcome of infection by one pathogen may be modulated by a change in the host environment brought on by infection by another pathogen. We investigated the host-mediated interaction between the biotroph Blumeria graminis f.sp. tritici (Bgt), the powdery mildew pathog...
