Two new species of Peronosporaceae (downy mildews) from Iran
In survey of infected samples to downy mildew of broadbean, Chenopodium murale and Rumex chalpensis using Olympus microscope (BH2) and valid keys and recently published papers, two species were identified (Choi et al. 2009, Ershad 2009, Telle & Thines 2012).
متن کاملBaobabopsis, a new genus of graminicolous downy mildews from tropical Australia, with an updated key to the genera of downy mildews.
So far 19 genera of downy mildews have been described, of which seven are parasitic to grasses. Here, we introduce a new genus, Baobabopsis, to accommodate two distinctive downy mildews, B. donbarrettii sp. nov., collected on Perotis rara in northern Australia, and B. enneapogonis sp. nov., collected on Enneapogon spp. in western and central Australia. Baobabopsis donbarrettii produced both oos...
متن کاملMultiple origins of downy mildews and mito-nuclear discordance within the paraphyletic genus Phytophthora
Phylogenetic relationships between thirteen species of downy mildew and 103 species of Phytophthora (plant-pathogenic oomycetes) were investigated with two nuclear and four mitochondrial loci, using several likelihood-based approaches. Three Phytophthora taxa and all downy mildew taxa were excluded from the previously recognized subgeneric clades of Phytophthora, though all were strongly suppor...
متن کاملEpidemiology and population biology of Pseudoperonospora cubensis: a model system for management of downy mildews.
The resurgence of cucurbit downy mildew has dramatically influenced production of cucurbits and disease management systems at multiple scales. Long-distance dispersal is a fundamental aspect of epidemic development that influences the timing and extent of outbreaks of cucurbit downy mildew. The dispersal potential of Pseudoperonospora cubensis appears to be limited primarily by sporangia produc...
