DOR:98.1000/1735-0859.1397.16.146.32.2.1605.1606 به منظور بررسی و شناسایی سفیدکهای سطحی استان لرستان اقدام به جمعآوری قارچهای مولد سفیدک سطحی (Erysiphales) از پارکها، مزارع و رویشگاههای طبیعی شد. پس از شناسایی گیاهان و میکرومتری اندامهای قارچی و ثبت مشخصات مورفولوژیک در نهایت با استفاده از کلیدهای شناسایی و مقالات معتبر قارچهای عامل سفیدک پودری شناسایی شدند. در این بررسی گونههای Er...
The common powdery mildew plant diseases are caused by ascomycete fungi of the order Erysiphales. Their characteristic life style as obligate biotrophs renders functional analyses in these species challenging, mainly because of experimental constraints to genetic manipulation. Global large-scale ("-omics") approaches are thus particularly valuable and insightful for the characterisation of the ...
Podosphaera is a genus of the powdery mildew fungi belonging to the tribe Cystotheceae of the Erysiphaceae. Among the host plants of Podosphaera, 86 % of hosts of the section Podosphaera and 57 % hosts of the subsection Sphaerotheca belong to the Rosaceae. In order to reconstruct the phylogeny of Podosphaera and to determine evolutionary relationships between Podosphaera and its host plants, we...
Phylogenetic relationships of the Uncinula lineage, which is the basal group in the genus Erysiphe, were investigated with 167 sequences of nuc ITS1-5. 8S-ITS2 and the 28S rDNA regions. Backbone tree analyses with six datasets and two tree-constructing methods revealed that the Uncinula lineage is divided into seven distinct clades. Clades 1-5 each contained a representative powdery mildew spec...
during the study of powdery mildew related to erysiphaceae family from abardeh region in mashhad (khorasan-e-razavi province), one species of rose (rosa persica michx.ex juss, summer 2006) with symptoms of powdery mildew was collected. the symptoms observed with the naked eye including the dense cottony shape mycelia infected the leaf surfaces as well as some parts of the stem. mycelia were den...
