RAPD-PCR genetic markers were used to assess variation in wheat plants and connections among six genotypes. Four random primers produced 140 DNA fragments, averaging 6.7 identifiable bands per primer. Among the genotypes, 85 pieces (44.64 percent) polymorphic. Several RAPD marker had distinct signify recurrence patterns that thing differently amongst germplasm of groupings. Within-community acc...
مقدمه: لیشمانیوز به ویژه از نوع جلدی به صورت یک مشکل مهم بهداشتی در بسیاری از نقاط ایران از جمله شهر نیشابور در استان خراسان رضوی مطرح میباشد. گونههای متفاوتی از این انگل سبب ایجاد بیماری شده و تعیین گونههای آن جهت کنترل و پیشگیری از بیماری لازم است. از طرفی تمام گونهها و سویههای متعلق به جنس لیشمانیا از نظر مورفولوژیک یکسان هستند و تشخیص گونههای عامل سالک به صورت میکروسکوپی امکان پذیر نب...
مطالعه جمعیت های یک گونه هم از جنبه گونه زایی و هم از نظر تاکسونومی مورد توجه محققین می باشد. اگر چه این مطالعات بیشتر جنبه مورفولوژیک داشته است و در حال حاضر بیشتر بر اساس تفاوت های ژنتیکی بین جمعیت ها استوار است. در این مطالعه چهار جمعیت گیاه علف لیمو cymbopogon olivieri از مناطق بنگود و زرچین در استان کرمان و باغات و شهداد در استان هرمزگان مورد بررسی قرار گرفتند. میزان اسانس چهار جمعیت مختلف...
Randomly amplified polymorphic DNA (RAPD) and pulsed-field gel electrophoresis (PFGE) for the analysis of 13 Moraxella catarrhalis isolates, 11 successive strains isolated from sputa of five children and 2 isolates obtained the same day from twins, were compared. RAPD and PFGE both yielded nine types from the 13 isolates, showing a chronic colonization with one strain in three patients and a su...
We compared random amplified polymorphic DNA (RAPD) fingerprinting with cross-absorption agglutination and restriction enzyme analysis for typing bovine leptospires. Using RAPD fingerprinting, we examined a number of Leptospira serovars, namely, hardjo genotypes bovis and prajitno, pomona, balcanica, tarassovi, swajizak, kremastos, australis, and zanoni, which are likely to be isolated from Aus...
In this study, the discriminatory power of pulsed field gel electrophoresis (PFGE) and random amplified polymorphic DNA (RAPD) methods for subtyping of 54 clinical isolates of Klebsiella pneumoniae were compared. All isolates were typeable by RAPD, while 3.6% of them were not typeable by PFGE. The repeatability of both typing methods were 100% with satisfying reproducibility (≥ 95%). Although t...
PURPOSE We examined the relationship between relative afferent pupillary defects (RAPDs) and macular structural damage measured by macular thickness and macular ganglion cell-inner plexiform layer (mGCIPL) thickness in patients with glaucoma. METHODS A cross-sectional study was done of 106 glaucoma patients and 85 healthy individuals from the Diagnostic Innovations in Glaucoma Study. All subj...
Sesame (Sesamum indicum L.) is an ancient oilseed crop known for its nutty seeds and high-quality edible oil. It is an unexplored crop with a great economic potential. The present study deals with assessment of genetic diversity in the crop. Twenty two RAPD and 18 SSR primers were used for analysis of the 47 different sesame accessions grown in different agroclimatic zones of India. A total of ...
Impact assessment of contaminants in soil is an important issue in environmental quality study and remediation of contaminated land. A random amplified polymorphic DNA (RAPD) 'fingerprinting' technique was exhibited to detect genotoxin-induced DNA damage of plants from heavy metal contaminated soil. This study compared the effects occurring at molecular and population levels in barley seedlings...
Six field strains of Ornithobacterium rhinotracheale isolated from chickens in Elazig province located in the East of Turkey were typed by serotyping and random amplified polymorphic DNA assay using a random primer (OPG-11). Using the AGP test used for serotyping, serotype A was found to be the predominant serotype, only one strain was serotyped as serotype B. By RAPD assay, the tested ORT stra...
