Molecular Techniques for Classification and Diagnosis of Plant Pathogenic Oomycota
2010With a delay of approximately 10 years, molecular techniques came in use for the investigation of phylogenetic, taxonomic, and diagnostic problems in oomycetes. The particular problem in plant pathogenic Oomycota lies in their biotrophic nature, which prohibits axenic cultivation of the majority of species, in particular downy mildews and white blister

The glaucophyte Glaucocystis nostochinearum has to our knowledge been observed to be infected by a parasite for the first time. It was found in samples taken from the northernmost freshwater pond in Germany (on the island of Sylt). The fungal parasite was identified as the oomycete Lagenidium sp.

Diversity and evolution of chitin synthases in oomycetes (Straminipila: Oomycota)
Molecular Phylogenetics and Evolution, 2019The oomycetes are filamentous eukaryotic microorganisms, distinct from true fungi, many of which act as crop or fish pathogens that cause devastating losses in agriculture and aquaculture. Chitin is present in all true fungi, but it occurs in only small amounts in some Saprolegniomycetes and it is absent in Peronosporomycetes.

Aplanes braunii (Phylum Oomycota) causes mortality in Anabas cobojius
Mycopathologia, 2003The fresh water fish Anabas cobojius (Hamilton-Buchanan 1822), was found to be parasitised by Aplanes braunii de Bary 1888. It is the first report of Aplanes braunii to cause disease on any fish. A. braunii is a virulent parasite that caused cotton-wool disease involving the skin, fins and muscles of A. cobojius.

Genome Size Determination in Peronosporales (Oomycota) by Feulgen Image Analysis
Fungal Genetics and Biology, 1998Genome size was determined, by nuclear Feulgen staining and image analysis, in 46 accessions of 31 species of Peronosporales (Oomycota), including important plant pathogens such as Bremia lactucae, Plasmopara viticola, Pseudoperonospora cubensis, and Pseudoperonospora humuli. The 1C DNA contents ranged from 0.046 (45. 6 Mb) to 0.163 pg (159.9 Mb). This

Revision of Plasmopara (Oomycota, Peronosporales) parasitic to Impatiens
Mycological Progress, 2017The oomycete Plasmopara obducens was first described on wild Impatiens noli-tangere in Germany in 1877. About 125 years later the first occurrence of P. obducens on cultivated I. walleriana in the United Kingdom was reported, and a worldwide epidemic followed.

3 Systematics of the Straminipila: Labyrinthulomycota, Hyphochytriomycota, and Oomycota
2014This is an account of the molecular systematics and phylogeny of the osmotrophic stramenopile lineages traditionally studied by mycologists, which include the Labyrinthulomycota, Hyphochytriomycota, and Oomycota. All three groups produce zoospores with a mastigonate anterior flagellum, and all fall within Kingdom Straminipila, which is part of the ...

Characterization of native crystalline cellulose in the cell walls of Oomycota
Journal of Biotechnology, 1997Abstract Cellulose samples from 4 Oomycetes species ( Saprolegnia parasitica , Pythium aphanidermatum , Pythium butleri and Phytophtora cactorum ) have been investigated. They were purified by mild hydrolysis of the cell walls, followed by extraction in diluted NaOH.

Taxonomic and phylogenetic analysis of the Oomycota mosquito larvae pathogen Crypticola clavulifera
Fungal Biology, 2018Beside the taxonomic features displayed by Crypticola clavulifera in culture and unpublished data on its phylogeny, little is known about the main phylogenetic features of this unusual mosquito pathogen. We have PCR amplified the 18S SSU rDNA, ITS, and the partial coding regions of COXII and COXI to study the phylogenetic features of this pathogen ...
