Powdery mildews are a diverse group of pathogenic fungi that can infect a large number of plant species, including many economically important crops. However, basic and applied research on these devastating diseases has been hampered by the obligate biotrophic lifestyle of the pathogens, which require living host cells for growth and reproduction, and lacking genetic and molecular tools for imp...

Abstract Grapevine powdery mildew is caused by Erysiphe necator that seriously harms grape production in the world. Stilbene synthase makes phytoalexins contribute to resistance of grapevine against mildew. A novel VqNSTS3 was identified and cloned from Chinese wild Vitis quinquangularis accession Danfeng-2. Novel transferred into susceptible ‘Thompson Seedless’ Agrobacterium-mediated transform...

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...

Abstract Golovinomyces longipes is a widespread powdery mildew on Solanaceae ( Nicotiana , Petunia and Solanum spp.). In the past, it has been reported only once Verbena Verbenaceae ), non-solanaceaous host. Recently, this found composite Matricaria chamomilla . The identification of species unusual host proved by morphological studies DNA sequence analysis. Both datasets coincide with characte...
