Peronosporaceae species causing downy mildew diseases of Poaceae, including nomenclature revisions and diagnostic resources. [PDF]

Fungal Syst Evol, 2022
Downy mildew pathogens of graminicolous hosts (Poaceae) are members of eight morphologically and phylogenetically distinct genera in the Peronosporaceae (Oomycota, Peronosporales). Graminicolous downy mildews (GDMs) cause severe losses in crops such as maize, millets, sorghum, and sugarcane in many parts of the world, especially in tropical climates ...

Pathogenicity of Botryosphaeriaceae and Phytophthora species associated with Paulownia dieback, canker and root rot in Italy

Phytopathologia Mediterranea, 2023
In recent years, an unusual decline and mortality has been observed in Paulownia plantations throughout the Marche region (Central Italy). Given the economic importance of this emerging forest crop, a study was conducted to determine which pathogens are ...

Phytophthora heterospora sp. nov., a New Pseudoconidia-Producing Sister Species of P. palmivora

Journal of Fungi, 2021
Since 1999, an unusual Phytophthora species has repeatedly been found associated with stem lesions and root and collar rot on young olive trees in Southern Italy. In all cases, this species was obtained from recently established commercial plantations or

Evolution, Diversity, and Taxonomy of the Peronosporaceae, with Focus on the Genus Peronospora [PDF]

Phytopathology®, 2016
Downy mildews are a notorious group of oomycete plant pathogens, causing high economic losses in various crops and ornamentals. The most species-rich genus of oomycetes is the genus Peronospora. This review provides a wide overview of these pathogens, ranging from macro- and micro-evolutionary patterns, their biodiversity and ecology to short ...

The Diversification of Downy Mildew Species Was Not Driven by the Loss of Mycorrhizal Associations or the Evolution of C4 Photosynthesis

PhytoFrontiers, 2022
There are approximately 700 obligate biotrophic species grouped into 20 genera (Oomycota, Peronosporaceae) that cause downy mildew diseases. In 2001, Dick hypothesized that diversification of downy mildew species was driven in part by host plant ...

Relación de Tecia solanivora (Povolný, 1973) (Lepidoptera: Gelechiidae) y el tizón tardío Phythopthora infestans (Mont.) de Bary, 1876 (Peronosporales: Peronosporaceae) con la fenología de la papa Solanum tuberosum Linnaeus, 1753 (Solanales: Solanaceae)

Revista Chilena de Entomología, 2022
El cultivo de papa es el cuarto en importancia mundial, en Colombia Tecia solanivora (Povolný) y Phythopthora infestans (Mont.) de Bary son limitantes que afectan su producción. Se evaluó la relación de la polilla guatemalteca y el tizón tardío en campo.

Phytopythium leanoi sp. nov. and Phytopythium dogmae sp. nov., Phytopythium species associated with mangrove leaf litter from the Philippines

Acta Mycologica, 2018
The genus Phytopythium is a monophyletic taxon of the Peronosporaceae with characteristics intermediate between Phytophthora and Pythium. In the Philippines, reports of Phytopythium are scarce, with the mangrove-swamp-inhabiting species Phytopythium ...

Ancestral chromosomes for the Peronosporaceae inferred from a telomere-to-telomere genome assembly of Peronospora effusa [PDF]

, 2021
Abstract We report the first telomere-to-telomere genome assembly for an oomycete. This assembly has extensive synteny with less complete genome assemblies of other oomycetes and will therefore serve as a reference genome for this taxon.
