به منظور ارزیابی تنوع ژنتیکی قارچ عامل بیماری آنتراکنوز گردو ophiognomonia leptostyla در شمالغرب ایران تعداد 25 جدایه از مناطق مختلف جمعآوری و با استفاده از روش تک اسپورسازی خالص شدند. استخراج dna از میسلیوم قارچ با استفاده از روش لیو و همکاران انجام شد. تکثیر منطقه its-rdna توسط جفت آغازگر اختصاصی، its1 و its4 انجام گردید. همچنین منطقه igs-rdna با استفاده از جفت آغازگر ns1r و lr13r تکثیر ش...
The M-protein genes (emm genes) of 103 separate impetiginous Streptococcus pyogenes isolates were sequenced and the sequence types were compared to the types obtained by Vir typing. Vir typing is based on restriction fragment length polymorphism (RFLP) analysis of a 4- to 7-kb pathogenicity island encoding emm and other virulence genes. By using both HaeIII and HinfI to generate RFLP profiles, ...
Genetic analysis was conducted in chicken belonging to lines divergently selected for high or low frequency of skeletal defects (line H and L, respectively). The analysis was based on the DNA fingerprinting technique, using enzyme HinfI and Jeffrey’s 33.6 probe. Principal aims were: 1) to determine the effects of selection on the genetic variation within and between lines, and 2) to search for ...
استخراج dna از تخم و لارو سن دوم نماتد با روش فنل - کلروفرم در مورد جمعیت هایی از گونه های meloidogyne javanica و meloidogyne incognita از ایران انجام و پس از تعیین کمیت و کیفیت، جهت انجام آزمون واکنش زنجیره ای پلیمراز (pcr) مورد استفاده قرار گرفت. با استفاده از آغازگرهای اختصاصی c2f3 / 1108 (20 و 23 نوکلئوتیدی)، قسمتی از dna میتوکندریایی مربوط به ژن کد کننده سیتوکروم اکسیداز، تکثیر و یک نوار 7...
Aim: The present study was undertaken with the objectives to characterize, identify DNA polymorphism in cluster of differentiation 14 (CD14) gene in Karan Fries (KF) cattle and to analyze association between genetic variants with incidence of clinical mastitis in National Dairy Research Institute (NDRI) herd, Karnal. Materials and Methods: Genomic DNA was extracted using blood of randomly selec...
A phylogenetic tree based on 150 5' untranslated region sequences deposited in GenBank database allowed segregation of the sequences into three major groups, including two subgroups, i.e., 1, 2a, 2b, and 3, supported by bootstrap analysis. Restriction site analysis of these sequences predicted that HinfI and either AatII or AciI could be used for genomic typing with 99.4% accuracy. cDNA sequenc...
The six major hepatitis C virus genotypes were investigated by using samples from 79 seropositive and PCR-positive blood donors from three different regions of South Africa as well as 9 patients with chronic renal failure, 19 with liver disease, and 23 with hemophilia. PCR products of the genome were typed by restriction fragment length polymorphic analysis by RsaI-HaeIII and MvaI-HinfI double ...
A survey of the genetic polymorphisms produced by distinct methods was performed in 23 commercial winery yeast strains. Microsatellite typing, using six different loci, an optimized interdelta sequence analysis and restriction fragment length polymorphism of mitochondrial DNA generated by the enzyme HinfI had the same discriminatory power: among the 23 commercial yeast strains, 21 distinct patt...
Objective(s): Iran is considered as one of the high-prevalence areas for β-thalassemia with a rate of about 10% carrier frequency. Molecular diagnosis of the disease is performed both by direct sequencing and indirectly by the use of polymorphic markers present in the beta globin gene cluster. However, to date there is no reliable information on the application of the markers in the Iranian pop...
Acetyl-coenzyme A carboxylase α (ACC-alpha) is considered as the key regulatory enzyme in fatty acid biosynthesis. ACC-alpha gene is located on Caprine chromosome 11 and is polymorphic in many goat breeds. In the current study, we aimed to find possible single nucleotide polymorphisms (SNPs) in the exon 1 region of the ACC-alpha gene in Iranian Mahabadi goat breed. Genomic DNA was extracted fro...
