Analysis of microsatellites from the transcriptome of downy mildew pathogens and their application for characterization of Pseudoperonospora populations
Downy mildew pathogens affect several economically important crops worldwide but, due to their obligate nature, few genetic resources are available for genomic and population analyses. Draft genomes for emergent downy mildew pathogens such as the oomycete Pseudoperonospora cubensis, causal agent of cucurbit downy mildew, have been published and can be used to perform comparative genomic analysi...
متن کاملConvention I . H . G . C . Proceedings of the Scientific Commission
Hop downy mildew (Pseudoperonospora humuli) and hop powdery mildew (Sphaerotheca humuli) are the most important fungal plant diseases of hop (Humulus lupulus). The early detection and diagnosis of pathogens are often aggravated with symptomless before mass infection or commutation with another pathogens. Molecular analysis of internal transcribed spacer (ITS) regions of rDNA is a novel and very...
متن کاملGenetic and pathogenic relatedness of Pseudoperonospora cubensis and P. humuli.
The most economically important plant pathogens in the genus Pseudoperonospora (family Peronosporaceae) are Pseudoperonospora cubensis and P. humuli, causal agents of downy mildew on cucurbits and hop, respectively. Recently, P. humuli was reduced to a taxonomic synonym of P. cubensis based on internal transcribed spacer (ITS) sequence data and morphological characteristics. Nomenclature has ma...

متن کاملIdentification of QTLs conferring resistance to downy mildew in legacy cultivars of lettuce
Many cultivars of lettuce (Lactuca sativa L.), the most popular leafy vegetable, are susceptible to downy mildew disease caused by Bremia lactucae. Cultivars Iceberg and Grand Rapids that were released in the 18th and 19th centuries, respectively, have high levels of quantitative resistance to downy mildew. We developed a population of recombinant inbred lines (RILs) originating from a cross be...
