Phylogenetic and sequence analysis of the growth hormone gene of two sturgeons, Huso huso and Acipenser Gueldenstaedtii
In this study, the cDNA Growth Hormone (cGH) of the Belugasturgeon (Husohuso) and Russian sturgeon (Acipensergueldenstaedtii) were cloned and sequenced, and phylogenetic relationships were examined using nucleic acid and amino acid sequences. The nucleotide sequence of the Beluga GH has an open reading frame of 645 nucleotides encoding a protein 214 amino acid residues. The signal peptide cleav...
متن کاملSequence Analysis and Phylogenetic Profiling of the Nonstructural (NS) Genes of H9N2 Influenza A Viruses Isolated in Iran during 1998-2007
The earliest evidences on circulation of Avian Influenza (AI) virus on the Iranian poultry farms date back to 1998. Great economic losses through dramatic drop in egg production and high mortality rates are characteristically attributed to H9N2 AI virus. In the present work non-structural (NS) genes of 10 Iranian H9N2 chicken AI viruses collected during 1998-2007 were fully sequenced and subjec...
متن کاملPhylogenetic Analysis of Three Long Non-coding RNA Genes: AK082072, AK043754 and AK082467
Now, it is clear that protein is just one of the most functional products produced by the eukaryotic genome. Indeed, a major part of the human genome is transcribed to non-coding sequences than to the coding sequence of the protein. In this study, we selected three long non-coding RNAs namely AK082072, AK043754 and AK082467 which show brain expression and local region conservation among vertebr...
متن کاملPhylogenetic Analysis of Beta-Glucanase Producing Actinomycetes Strain TBG-CH22 - A Comparison of Conventional and Molecular Morphometric Approach
Actinomycetes are inexhaustible producers of commercially valuable metabolites, are continually screened for beneficial compounds. The taxonomic and phylogenetic study of novel actinomycetes strains are mostly based on conventional methods and primary DNA structure of 16s rRNA. Although 16s rRNA sequence is well accepted in phylogeny studies, its secondary structures have not been widely used. ...
متن کاملA comparative phylogenetic analysis of Theileria spp. by using two two "18S ribosomal RNA" and "Theileria annulata merozoite surface antigen" gene sequences
More than 185 species, strains and unclassified Theileria parasites are categorized in the Entrez Taxonomy. The accurate diagnosis and proper identification of the causative agents are important for understanding the epidemiology, prevention and appropriate treatment. This study aims to discuss the importance of two genes of Theileria annulata 18S ribosomal RNA (18S rRNA) and Theileria annulata...
متن کاملPhylogenetic analysis of two Iranian grapevine virus A isolates using coat protein gene sequence
Symptomatic grapevine samples were collected from vineyards in Zanjan province to detect Grapevine virus A. Total RNA was extracted from symptomatic leaf samples and subjected to cDNA synthesis using random hexamer primers. Then, a DNA fragment around 800 bp including the complete coat protein (CP) gene was amplified from nine out of 57 samples by polymerase chain reaction (PCR) using specific ...
