The photoactivated toxin, cercosporin, produced by Cercospora species, plays an important role in pathogenesis of this fungus to host plants. Cercosporin has almost universal toxicity to cells due to its production of reactive oxygen species including singlet oxygen. For that reason, Cercospora species, which are highly resistant to their own toxin, are good candidates to identify genes for res...

A common bean truncated CRINKLY4 kinase controls gene-for-gene resistance to the fungus Colletotrichum lindemuthianum. Journal of Experimental Botany 72, 3569–3581.

The use of antifungal drugs in the therapy of fungal diseases can lead to the development of antifungal resistance. Resistance has been described for virtually all antifungal agents in diverse pathogens, including Candida and Aspergillus species. The majority of resistance mechanisms have also been elucidated at the molecular level in these pathogens. Drug resistance genes and genome mutations ...

Although different mechanisms have been proposed in the recent years, plant pathogen partial resistance is still poorly understood. Components of the chemical warfare, including the production of plant defense compounds and plant resistance to pathogen-produced toxins, are likely to play a role. Toxins are indeed recognized as important determinants of pathogenicity in necrotrophic fungi. Parti...

In a field experiment with a susceptible population of annual wild carrot (Daucus carota) from Iran, artificial inoculations with the fungal pathogen A. dauci led to a strong and very significant increase of the diseased leaf area. The pathogen caused a very significant decrease in fecundity and seed survival of the host. This considerable fitness reduction by A. dauci would suggest that introg...

Septoria tritici blotch (STB), caused by the ascomycete fungus Mycosphaerella graminicola (asexual stage: Septoria tritici), is one of the most important foliar diseases of wheat. In this research, quantitative expression analysis of five candidate genes for the induction of resistance to STB (PR-1, Bsi, Msr, Per, and Ppi) was conducted in the wheat cultivars ‘Seri 82’ (susceptible) and ‘Fronta...

Antibiotic resistance is a critical threat to human and animal health. Despite the importance of antibiotics, regulators continue to allow antibiotics to be used in low-value applications--subtherapeutic dosing in animals, and spraying tobacco plants for blue mold, for example--where the benefits are unlikely to outweigh the costs in terms of increased resistance. We explore the application of ...

Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is a major constraint in global wheat production. The lack of genetic diversity modern elite cultivars largely hinders improvement STB resistance. Wheat landraces are reservoirs untapped diversity, which can be exploited to find novel resistance genes or alleles. Here, we characterized 188 Swiss for using four Z. isolates...
