Glutinoglossum is a recently described genus in Geoglossomycetes, characterized by viscid black fruiting bodies. Glutinoglossum was described based on molecular evidence showing that the fungus formerly known as Geoglossum glutinosum formed a well-supported clade separate from Geoglossum. This study provides a comprehensive examination of Glutinoglossum based on maximum-likelihood and Bayesian ...
A new feather mites species, Proctophyllodes valchukae sp. n., is described from the Long-tailed Tit, Aegithalos caudatus (Linnaeus, 1758) (Passeriformes: Aegithalidae), captured in the Primoriye (Russian Far East). The new species belongs to the tricetratus species group and is most closely related to P. stachyris Atyeo et Braasch, 1966. For the first time for feather mites the standard morpho...
The data of the is presented. technology allows to identify entire spectrum organisms in an experimental sample per one cycle, while separate study for each potentially contained component previously was required. An integrated approach submitted as a method early diagnosis causative agents main fungal diseases during silver birch ( Betula pendula Roth ) and downy pubescens Ehrh. plants. It bas...
In this study, integrative taxonomy is applied to describe a new dactylogyrid species, Ameloblastella pirarara sp. n. from the gills of Phractocephalus hemioliopterus, commercially and ecologically important Amazonian catfish. can be distinguished its congeners mainly by morphology male copulatory organ (MCO), accessory piece, anchors. The species most resembles unapi, Peruvian Amazon, but diff...
(1) Background: Integrative taxonomy has been important in the comprehension of relationships among nematode parasites. Philometridae is a highly diverse family these organisms, but poorly-known regarding genetic characterization and evolution. An integrative taxonomic analysis was performed to improve knowledge evolutionary history Philometridae. (2) Methods: Phylogenies were reconstructed bas...
Specimens of Poecilosclerida taxa, collected from an insular coral community on the Pacific coast Mexico, were identified as members family Crambeidae Lévi, 1963. They associated with larvae and rhagon phases by using morphological characters, nucleotide relationship genetic divergence three independent loci, two mitochondrial (COI 16S rDNA) one ribosomal (28S rDNA C3–C5). Crambe insularis sp. ...
در این پژوهش، 12 سویۀ بومی و 80 سویه از گونههای شناختهشدۀ سه جنس Allophoma،Didymella و Neodidymelliopsis گزینش شدند و در یک تجزیهوتحلیل تبارزایشی جهت همسنجی ناحیههای ژنی ITS، دومین D1 و D2 از زیرواحد بزرگ ژن ریبوزومی (D1/D2 LSU rDNA)، بتاتوبولین و RNA پلیمراز در جداسازی گونهها استفاده شدند. ناحیههای ژنی سویههای بومی با بهکارگیری DNA استخراجشده از زیستتودۀ میسیلیومی خشکانجمادی شده...
R2 retrotransposable elements exclusively insert into the tandemly repeated rRNA genes, the rDNA loci, of their animal hosts. R2 elements form stable long-term associations with their host, in which all individuals in a population contain many potentially active copies, but only a fraction of these individuals show active R2 retrotransposition. Previous studies have found that R2 RNA transcript...
نماتد سیستی سیبزمینی،Globodera rostochiensis در سال 1387 از مزارع سیبزمینی شهرستان بهار در استان همدان گزارش شد. جهت تعیین پاتوتیپ G. rostochiensis، تعداد ده جمعیت از مزارع آلوده سیبزمینی در منطقه بهار جمعآوری شد. شناسایی گونه بر اساس خصوصیات ریختشناسی و ریختسنجی لاروهای سن دوم و سیستها و با استفاده از آغازگر اختصاصی گونه و تعیین ترادف نوکلئوتیدی ناحیه D2-D3 از ژن زیر...
