با توجه به اهمیت میگوی سرتیز (Metapenaeus affinis) در چرخه صیادی خلیجفارس، بررسی مقدماتی ساختار ژنتیکی جمعیت این گونه با توالییابی ژن میتوکندریایی 16S rRNA انجام شد. تعداد 18 قطعه میگو از سه منطقه بندرعباس، بوشهر و خ...
Gonyostmum semen is a freshwater raphidophyte that has increased in occurrence and abundance in several countries in northern Europe since the 1980s. More recently, the species has expanded rapidly also in north-eastern Europe, and it is frequently referred to as invasive. To better understand the species history, we have explored the phylogeography of G. semen using strains from northern Europ...
Morphological and molecular characteristics of spirometrid tapeworms, Spirometra decipiens, were studied, which were recovered from a heavily infected stray cat road-killed in Eumseong-gun, Chungcheongbuk-do (Province), the Republic of Korea (=Korea). A total of 134 scolices and many broken immature and mature proglottids of Spirometra tapeworms were collected from the small intestine of the ca...
گاو در تمدن انسان ابتدایی نقش مهمی داشته است بنابراین مطالعه خاستگاه این حیوان می تواند به ما جهت شناختن جنبه های ناشناخته تاریخ کمک کند. نژادهای گاو را می توان به دو گروه اصلی تائورین بدون کوهان و زبوی کوهان دار تقسیم کرد. با توجه به اینکه اکثر گاوهای ایرانی از زیر گروه کوهان دار می باشند، لذا مطالعه آنها از اهمیت خاصی برخوردار می باشد. این مطالعه جهت بررسی توالی جایگاههای ژنی cytochrome b و d...
Species identification of Taenia tapeworms was performed using morphologic observations and multiplex PCR and DNA sequencing of the mitochondrial cox1 gene. In 2008 and 2009, a total of 1,057 fecal samples were collected from residents of Kongwa district of Dodoma region, Tanzania, and examined microscopically for helminth eggs and proglottids. Of these, 4 Taenia egg positive cases were identif...
The Rieske FeS protein, an essential catalytic subunit of the mitochondrial cytochrome bc1 complex, is encoded in yeast by the nuclear gene RIP1, whose deletion leads to a respiratory-deficient phenotype. By using biolistic transformation, we have relocated the nuclear RIP1 gene into mitochondria. To allow its expression within the organelle and to direct its integration downstream of the cox1 ...
The assembly of cytochrome c oxidase (CcO) in yeast mitochondria is shown to be dependent on a new assembly factor designated Coa1 that associates with the mitochondrial inner membrane. Translation of the mitochondrial-encoded subunits of CcO occurs normally in coa1Delta cells, but these subunits fail to accumulate. The respiratory defect in coa1Delta cells is suppressed by high-copy MSS51, MDJ...
Group I introns are mobile, self-splicing genetic elements found principally in organellar genomes and nuclear rRNA genes. The only group I intron known from mitochondrial genomes of vascular plants is located in the cox1 gene of Peperomia, where it is thought to have been recently acquired by lateral transfer from a fungal donor. Southern-blot surveys of 335 diverse genera of land plants now s...
The definitive hosts of Sarcocystis sinensis in water buffaloes have hitherto been unknown, but the close similarity of this species to the cat-transmitted Sarcocystis bovifelis in cattle suggested they were felids. In a previous study, two domestic cats were fed macroscopic sarcocysts of Sarcocystis fusiformis contained within or dissected from the esophageal muscles of water buffaloes, while ...
Saccharomyces cerevisiae cells lacking the cytochrome c oxidase (CcO) assembly factor Coa2 are impaired in Cox1 maturation and exhibit a rapid degradation of newly synthesized Cox1. The respiratory deficiency of coa2 Delta cells is suppressed either by the presence of a mutant allele of the Cox10 farnesyl transferase involved in heme a biosynthesis or through impaired proteolysis by the disrupt...
