مقدمه: استرپتوکوکوس پیوژنز بیماریهای عفونی و غیرعفونی متنوعی را ایجاد میکند. تایپینگ جدایههای استرپتوکوکوس پیوژنز یکی از ابزارهای ضروری در مطالعات اپیدمیولوژی مربوط به این باکتری هستند. RAPD-PCR یک تکنیک تایپینگ بر اساس PCR و روشی سریع، ارزان، آسان است. مشکل اصلی این روش تکرارپذیری کم نتایج است که با بهینه سازی پروتکل RAPD حل خواهد شد.مواد و روشها: در این مطالعه بهی...
Molecular markers are used in plant science a variety of ways. The method molecular genome marking based on RAPD-PCR makes it possible to determine the genetic status populations and establish intrapopulation relationships. In this work, we studied polymorphism dandelion Taraxacum officionale using RAPD markers. Five random amplified polymorphic DNA (RAPD) were diversity relationship between tw...
This study reports the genetic variations between populations of the red palm weevil, Rhynchophorus ferrugineus in the UAE area. To test if the red palm weevil population in the UAE belongs to the same genetic group; the randomly amplified polymorphic DNA (RAPD) technique was used to assay seven populations of the insect from different locations. RAPD primer pairs detected a total 216 RAPD frag...
Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of ten experimental materials in Rehmannia glutinosa Libosch .f. hueichingensis (Chao et Schih) Hsiao, including eight cultivars and two virus-free lines micropropagated by tip tissue culture from Wenxian county. A high level of polymor...
کشت بافت و سلول یکی از مهمترین تکنیک ها در اصلاح ژنتیکی و ریزازدیادی سلول ها و بافت های یونجه محسوب می شود. کشت بافت سبب ایجاد تنوع ژنتیکی و اپی ژنتیکی می گردد که اصطلاحاً تنوع سوماکلونال گفته می شود. اگر چه این تنوع می تواند در برنامه های اصلاحی مفید باشد، ولی در استفاده از این تکنیک در ریزازدیادی و دستکاری های ژنتیکی حفظ یکدستی ژنتیکی نسبت به گیاه مادری مهم است. تکنیک های متعددی به طور موفقیت ...
We have assayed genetic polymorphisms in several species of parasitic protozoa by means of random amplified polymorphic DNA (RAPD). One goal was to ascertain the suitability of RAPD markers for investigating genetic and evolutionary problems, particularly in organisms, such as the parasitic protozoa, unsuitable for traditional methods of genetic analysis. Another goal was to test certain hypoth...
Aim-To compare restriction fragment length polymorphism (RFLP) and random amplified polymorphic DNA (RAPD) methods for the epidemiological typing of Mycobacterium tuberculosis.Methods-Thirty one M tuberculosis cultures originating from patients in the Canton of Berne in Switzerland, which had previously been typed by RFLP, were subjected to RAPD analysis. Cultures were coded so that the investi...
Gypsophila L. is the 3rd-largest genus of Caryophyllaceae in Turkey, a country that includes 60 taxa belonging to 56 species of the 126 recognized in the genus. A total of 35 taxa are endemic to Turkey, with an approximately 60% endemism ratio. In this study, the genetic diversity of 14 Gypsophila species from Turkey was analyzed using random amplification of polymorphic DNA (RAPD) and inter-si...
This study evaluates the effectiveness of three different molecular techniques, repetitive extragenic palindromic PCR (REP-PCR), enterobacterial repetitive intergenic consensus sequence PCR (ERIC-PCR) and the random amplified polymorphic DNA (RAPD-PCR) for rapid typing of Photobacterium damselae ssp. piscicida strains isolated from different species of marine fish and geographic areas. The resu...
Chinese kale is an original Chinese vegetable of the Cruciferae family. To select suitable parents for hybrid breeding, we thoroughly analyzed the genetic diversity of Chinese kale. Random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) molecular markers were used to evaluate the genetic diversity across 21 Chinese kale accessions from AVRDC and Guangzhou in ...
