The alkaloid fuyuziphine was isolated from the whole plant of Fumaria indica. It had inhibitive effect against spore germination of some plant pathogenic fungi (Collectotrichum sp., C. gloeosporioides, C. falcatum, Curvularia maculans, C. lunata, Erysiphe cichoracearum, Helminthosporium pennisetti, Oidium erysiphoides, Ustilago cynodontis, Alternaria chieranthi, A. melongenae, A. brassicicola a...

We have identified an Arabidopsis mutant that displays enhanced disease resistance to the fungus Erysiphe cichoracearum, causal agent of powdery mildew. The edr1 mutant does not constitutively express the pathogenesis-related genes PR-1, BGL2, or PR-5 and thus differs from previously described disease-resistant mutants of Arabidopsis. E. cichoracearum conidia (asexual spores) germinated normall...

Abstract In central Europe, including Germany, Telekia speciosa (heart-leaved oxeye) is a synanthropic, non-native plant species commonly grown as an ornamental plant. A powdery mildew has recently been introduced on this host in Germany. This previously assigned to Golovinomyces cichoracearum (≡ Erysiphe ) sensu lato. Two German specimens of have sequenced and phylogenetically analysed. The an...

Surveys were carried out to determine species composition and host range of powdery mildews (Erysiphaceae) in Gilan province, Iran. Twenty seven taxa were identified. Among them Erysiphe circaeae, E. punicae, E. urticae, Microsphaera erlangshanensis, M. multappendicis, M. trifolii and Podosphaera clandestine/ var. cydonia are new to Iran. Parietaria officinalis and Phuopsis stylosa are new host...

We report a role for the Arabidopsis (Arabidopsis thaliana) RESURRECTION1 (RST1) gene in plant defense. The rst1 mutant exhibits enhanced susceptibility to the biotrophic fungal pathogen Erysiphe cichoracearum but enhanced resistance to the necrotrophic fungal pathogens Botrytis cinerea and Alternaria brassicicola. RST1 encodes a novel protein that localizes to the plasma membrane and is predic...
