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...
GDF9 gene is one of the most important effective factors on litter size in sheep. Thus, the aim of the present study was to detect single nucleotide polymorphisms (SNPs) available in exon 2 of GDF9 gene in pure and crossbred of Pakistani sheep using PCR-SSCP. Hence, blood samples were collected from 30 Pakistani sheep, 17 crossbred sheep (Pakistani rams × Lori-Bakhtiari) and 7 crossbred sheep (...
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....
UNLABELLED SNPNB is a user-friendly and platform-independent application for analyzing Single Nucleotide Polymorphism NeighBoring sequence context and nucleotide bias patterns, and subsequently evaluating the effective SNP size for the bias patterns observed from the whole data. It was implemented by Java and Perl. SNPNB can efficiently handle genome-wide or chromosome-wide SNP data analysis in...
Mastitis is one of the most serious and costly diseases affecting dairy cattle production. In the present study, effects of a lactoferrin gene polymorphism (intron 6) on milk somatic cell count (SCC) and subclinical mastitis was investigated in 121 Holstein dairy cattle. Two alleles of A and B and two genotypes of AA and AB were found in an EcoRI recognized single nucleotide polymorphism in int...
Population structure of sea cucumber Holothuria parva in the coasts of Bushehr and Halileh from Persian Gulf was determined by 16S rRNA of mitochondrial genome sequencing in autumn and winter seasons of 2019. In Bushehr and Halileh populations, 2 and 4 haplotypes were identified out of 374 nucleotide sites, respectively, and haplotype 2 was the most abundant in Bushehr population and was observ...
