Oomycetes are a diverse group of eukaryotes in terrestrial, limnic and marine habitats worldwide include several devastating plant pathogens, for example Phytophthora infestans (potato late blight). The cytochrome c oxidase subunit 2 gene (cox2) has been widely used identification, taxonomy phylogeny various oomycete groups. However, recently the cox1 was proposed as DNA barcode marker instead, together with ITS rDNA. locus some studies Pythium Phytophthora, but rarely other oomycetes,...
Downy mildews are a notorious group of oomycete plant pathogens, causing high economic losses in various crops and ornamentals. The most species-rich genus oomycetes is the Peronospora. This review provides wide overview these ranging from macro- micro-evolutionary patterns, their biodiversity ecology to short overviews for currently economically important pathogens potential emerging diseases. In this overview, taxonomy relevant species also discussed, as application correct names concepts...
Even though the microevolution of plant hosts and pathogens has been intensely studied, knowledge regarding macro-evolutionary patterns is limited. Having highest species diversity host-specificity among Oomycetes, downy mildews are a useful model for investigating long-term host-pathogen coevolution. We show that phylogenies Bremia Asteraceae significantly congruent. The accepted hypothesis have diverged contemporarily with their hosts. But maximum clade age estimation sequence divergence...
The obligate biotrophic lineages of the white blister rusts (Albuginales, Oomycota) are ancient origin compared to rather recently evolved downy mildews, and sophisticated mechanisms biotrophy a high degree adaptation diversity be expected in these organisms. Speciation Oomycetes is usually thought consequence host or geographic isolation. Here we report presence two distinct species Albugo on model plant Arabidopsis thaliana, candida laibachii, latter being formally described this...
The genus
Bremia lactucae is an obligate, oomycete pathogen of lettuce that causes leaf chlorosis and necrosis adversely affects marketability. The disease has been managed with a combination host resistance fungicide applications success over the years. Fungicide are routinely made under assumption inoculum always present during favorable environmental conditions. This approach often leads to in B. populations. Detection quantification airborne near crops provides estimation load, enabling more...
Small galls and white blisters with cup-like fungal structures were observed on the leaves of Machilus thunbergii (Lauraceae), a tree species native to East Asia. Based its distinctive symptoms aster-shaped spores, causal agent was identified as Asteroconium saccardoi. Despite unique characteristics, genus remains taxonomically unresolved (incertae sedis) within phylum Ascomycota due absence both sequence data available culture. The present study successfully obtained ITS LSU rDNA sequences...
Root and stem rot, caused by Pythiales (Oomycota), poses a significant threat to chrysanthemum (Chrysanthemum spp.) cultivation worldwide. In Korea, previously undocumented rot blight symptoms were observed on stems, roots, leaves of Chrysanthemum morifolium (=Dendranthema morifolium), species with high global production. This study identified the causal agents as Globisporangium ultimum Phytopythium helicoides based morphological features molecular phylogenetic analysis internal transcribed...
Pseudoperonospora cubensis is an oomycete pathogen causing downy mildew disease on a variety of Cucurbitaceae, and has recently re‐emerged as destructive crops in this family, mainly cucumber squash. Multilocus sequence analysis ( MLSA ) four mitochondrial two nuclear DNA regions was used to detect changes the genetic structure P. populations occurring Czech Republic that might be associated with reported shifts virulence. The analysed sample set contains 67 isolates collected from 1995 2012...
Oomycetes are widely distributed in various environments, including desert and polar regions. Depending upon different habits hosts, they have evolved with both saprophytic pathogenic nutritional modes. Freshwater ecosystem is one of the most important habitats for members oomycetes. Most studies on oomycete diversity, however, been biased mostly towards terrestrial phytopathogenic species, rather than aquatic although their roles as saprophytes parasites essential freshwater ecosystems. In...
In order to elucidate the fungal diversity and community structure in freshwater environments, numerous strains were isolated from freshwater, submerged soils, twigs, dead insects, etc. Among them, present study has focused specifically on Aspergillus, Penicillium, Talaromyces species, which produce diverse useful metabolites general. Twelve of Aspergillus identified as A. japonicus (n = 5), tubingensis (3), niger (2), flavus 10 belong section Nigri, named black Aspergillus. Eight...
