Fragments of amplified Xenopus laevis DNA, coding for 18S and 28S ribosomal RNA and generated by EcoRI restriction endonuclease, have been linked in vitro to the bacterial plasmid pSC101; and the recombinant molecular species have been introduced into E. coli by transformation. These recombinant plasmids, containing both eukaryotic and prokaryotic DNA, replicate stably in E. coli. RNA isolated ...
The two variable domains D1 and D2 near the 5' end of the 28S ribosomal RNA gene (large subunit rRNA) have been sequenced for Vespa crabro. The sequence was aligned to corresponding rDNA regions of the wasp species Nasonia vitripennis, Melittobia digitata and the fruit fly Drosophila melanogaster. We analysed the nucleotide composition and sequence similarity for the different regions of the in...
Fungi have unique properties and are used in many areas of agriculture industry because they can produce different enzymes. This study aims to the fungal diversity peat soil from Pontian Johor, Malaysia. The isolates were described on culture media a new medium called EVA identified using phenotypical characteristics molecular D1/D2 domain 28S large subunit ribosomal RNA (28S rRNA) ITS (ITS1-IT...
In a survey of undiscovered taxa in Korea, three zygomycete fungal strains-EML-W31, EML-HGD1-1, and EML-RUS1-1-were isolated from freshwater, grasshopper fecal, and soil samples in Korea. On the basis of the morphological characteristics and phylogenetic analysis of internal transcribed spacer and 28S rDNA, the isolates of EML-W31, EML-HGD1-1, and EML-RUS1-1 were confirmed to be Cunninghamella ...
helicotylenchus یکی از نماتود های انگل گیاهی است که باعث ایجاد خسارت به محصولات باغی و زراعی می شود. گونه های این جنس دارای گستردگی جهانی می باشند. هدف از این تحقیق شناسایی گونه های جنس helicotylenchus و آنالیز مولکولی برخی جمعیت ها با استفاده از ناحیه d2-d3 متعلق به ژن 28s rdna در برخی نقاط استان کرمان می باشد. تا کنون بررسی جامعی در این زمینه در استان کرمان صورت نگرفته است. باتوجه به این که گ...
The phylogenetic position of three taxa from two trematode genera, belonging to the subfamily Acanthostominae (Opisthorchioidea: Cryptogonimidae), were analysed using partial 28S ribosomal DNA (Domains 1-2) and internal transcribed spacers (ITS1-5.8S-ITS2). Bayesian inference and Maximum likelihood analyses of combined 28S rDNA and ITS1 + 5.8S + ITS2 sequences indicated the monophyly of the gen...
black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. in a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in kurdistan province (iran), some black meristematic fungal isolates re...
rhizoctonia zeae causes root rot and sheath blight on corn (zea mays) and several other gramineous plants. in order to determine the genetic diversity of the r. zeae population in mazandaran and golestan provinces, samples were collected from cultivatd soils of both provinces in 2011 and 2012.the identity of isolates as r. zeae were verified by amplification and sequencing of the 18s and 28s rd...
