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...

Grapevines are one of the most intensely treated crops with a high potential risk to health and biodiversity. Thus, distribution control agrochemicals is crucial obtain quality sustainable product for intensive viticulture. Although search systems reduce waste chemical products consistent in some countries, such as Italy, machinery used obsolete. The development an upgrading system sprayers can...

Pathogens belonging to the Oomycota, a group of heterokont, fungal-like organisms, are amongst the most notorious pathogens in agriculture. In particular, the obligate biotrophic downy mildews and the hemibiotrophic members of the genus Phytophthora are responsible for a huge variety of destructive diseases, including sudden oak death caused by P. ramorum, potato late blight caused by P. infest...

Abstract Muscadinia rotundifolia, the muscadine grape, has been cultivated for centuries in southeastern United States. M. rotundifolia is resistant to many of pathogens that detrimentally affect Vitis vinifera, grape species commonly used winemaking. For this reason, a valuable genetic resource breeding. Single-molecule real-time reads were combined with optical maps reconstruct two haplotypes...
