Maintaining genomic diversity in goat populations in different parts of Iran is essential for breeding programs, increasing production, survival, resistance to diseases, and various environmental changing conditions. The aim of the present study was to determine the sequence of HVR1 from the mitochondrial genome of Iranian native goats including Sistani, Pakistani, Black and Lorry ecotypes...
The Persian sturgeon, Acipenser persicus (Borodin, 1897), is an economically important species, which mainly inhabits the Caspian Sea. However, little is known about its population genetic structure. In this study, variation in nucleotide sequences of the mitochondrial DNA (mtDNA) control region of wild stock Persian sturgeon was determined to assess the genetic diversity among different natura...
The regular echinoids were recorded from Chennai Coast,Tamilnadu, South India and the animals were belong to 4 families, 5 genera and 5 species. An identification key to generic level and synoptic description are provided. Temnopleurid sea urchin Salmaciella oligopora (Clark, 1916) was recorded for the first time in 20-30m depth between Chennai and Pondicherry Coasts, South East Coast of India....
There is a lot of information about genes sequence but their functions are still unknown. So, to fill the gap between structure and function of these sequences many reverse genetic researches have been done. Current experiment studying, how to design gene-specific primers, that can determine single nucleotide diversity and its impact on gene function.This research was condacted at International...
RNAi mechanism plays a major role in silencing the expression of target genes by siRNAs. In the current study, in silico properties of 30 genes in omega-2 gliadin and 266 nt and 326 nt mutations were investigated before and after cloning in an expression vector. Specific primers were designed for 30 genes with spacer regions of 75 nt and 178 nt (for gene invert repeats). The frequency of siRNA ...
Detection of Mycoplasma synoviae (MS) by culture and polymerase chain reaction (PCR) has been reported from commercial chicken farms in different provinces of Iran. In some reports the phylogenetic analysis of MS isolates based on 16S rRNA and variable lipoprotein hemagglutinin (vlhA) genes have been carried out. The PCR product containing partial 16S rRNA genes of Iranain isolates was sequence...
To the best of our knowledge, little information is available regarding the presence of Anaplasma species in camels in Iran. This study sought to investigate the presence of Anaplasma species by microscopy and polymerase chain reaction (PCR) assays in 100 healthy dromedaries (Camelus dromedarius) arriving for slaughter. The microscopic examination of Giemsa-stained blood films revealed that Ana...
in the present study, the diversity of trichoderma spp. was investigated in alkaline pistachio soils at different geographic area in kerman province, iran. a total of 161 trichoderma isolates were obtained and identified at the species level by analysis of their morphological characters and sequence analysis of their internal transcribed spacer regions of the rrna cluster and tef1 genes as phyl...
It is difficult to distinguish between clinically significant slowly-growing, non-pigmented mycobacteria, notably to separate M. aviumand M. intracellulare from one another and from M. scrofulaceum strains. The purpose of this study was to evaluate the extent to which 16S rRNA sequencing could be used to highlight the taxonomic relationships of the mycobacterial strains, which are difficult to ...
