The Dothideomycete fungus Mycosphaerella graminicola is the causal agent of Septoria tritici blotch, a devastating disease of wheat leaves that causes dramatic decreases in yield. Infection involves an initial extended period of symptomless intercellular colonisation prior to the development of visible necrotic disease lesions. Previous functional genomics and gene expression profiling studies ...

The inoculation of soft wheat by Septoria tritici induces a foliar necrosis and an important modifications in the oxidative metabolism of which the time course clearly distinguishes the studied cultivars according to their behaviour to this disease. In the resistant cultivars (Mahdia, Achtar), the inoculation was accompanied by an early and localized necrosis and a fast and intense increase of ...

In modern cropping systems, the near-universal use of plant protection products selects for resistance in pest populations. The emergence and evolution this adaptive trait threaten treatment efficacy. We identified determinants fungicide quantified their effects at a large spatiotemporal scale. focused on Zymoseptoria tritici, which causes leaf blotch wheat. Phenotypes qualitative or quantitati...

Septoria centellae associated with leaf spot of Centella asiatica is reported for the first time in Korea. The fungus is described and illustrated in detail. It is also compared with related species of Septoria present on Centella and Hydrocotyle spp. with taxonomic comments. Two monoconidial isolates from Jeju and Wando were successfully cultured and have been deposited in the Korean Agricultu...
