Estimates of genetic diversity can be based on different types of data. The aim of this research were to study genetic diversity among Croatian wheat cultivars by random amplified polymorphic DNA (RAPD) markers, morphological traits and pedigree records; to analyse differences between wheat cultivars from two breeding centres; and to evaluate usability of RAPD markers for estimation of genetic ...
In the last decade, the random amplified polymorphic DNA (RAPD) technique based on the polymerase chain reaction (PCR) has been one of the most commonly used molecular techniques to develop DNA markers. RAPD is a modification of the PCR in which a single, short and arbitrary oligonucleotide primer, able to anneal and prime at multiple locations throughout the genome, can produce a spectrum of a...
در این مطالعه تنوع ژنتیکی 69 فرد از نه جمعیت طبیعی متعلق به دو گونه dianthus موجود درشمال شرق ایران با استفاده از داده های pard به منظور دستیابی به اطلاعات مهم ژنتیکی بررسی گردید. 111 باند چندشکلی با کمک 11 آغازگر rapd بدست آمد. درصد باندهای چند شکلی، تنوع ژنتیکی نی و اندیس شانون محاسبه گردید. دندروگرام بر اساس روش upgma جمعیتهای مورد بررسی را به دو گروه اصلی مطابق با دو گونه جدا نمود و نزدیکی ...
Forage kochia (Kochia prostrata ssp. virescens 'Immigrant' is native to the arid and semiarid regions of central Eurasia. It was introduced into the United States in 1966 as PI 314929 and released as a perennial forage shrub in 1984. Kochia americana is a perennial native to the United States, whereas Kochia scorparia is an introduced annual species that became a weed. To assess both the breedi...
Genetic variability in pepper genotypes has been widely assessed using phenotypic traits and molecular markers, which are essential to estimate the genetic divergence of species thus recommend parental individuals for breeding programs. In this scenario, study aimed evaluate between ornamental accessions (C. annuum L.) RAPD markers. Seventeen one plant commercial cultivar Calypso were used stud...
Chlorophytum borivilianum is a traditional medicinal plant distributed throughout the trop‐ ics and subtropics. In the present investigation, RAPD and ISSR analyses were used to assess the genetic diversity among 21 accessions collected from different geographical regions of India using 20 RAPD primers and 6 ISSR primers. RAPD and ISSR primers revealed 92.26% and 82.76% polymorphism, respective...
Visceral leishmaniasis (VL) is mainly due to the Leishmania donovani complex. VL is endemic in many countries worldwide including East Africa and the Mediterranean region where the epidemiology is complex. Taxonomy of these pathogens is under controversy but there is a correlation between their genetic diversity and geographical origin. With steady increase in genome knowledge, RAPD is still a ...
With random amplified polymorphic DNA (RAPD) markers, we have tagged a genomic region in Populus sp. involved in qualitative resistance to Melampsora larici-populina. Our approach was based on three steps: use of RAPD markers that can be quickly and efficiently researched: application of "bulked segregant analysis" technique on individuals of one interspecific family P. trichocarpa x P. deltoid...
Cadmium is a toxic unnecessary element for humans and plants which is easily absorbed by plants. Genetic variation in cadmium accumulation provides an opportunity for breeding programs to select genotypes with low cadmium. Due to the high cost of plant tissue analysis to determine the amount of cadmium, use of markers to make efficient selection of low cadmium accumulating genotypes is an effec...
Random amplified microsatellite polymorphism (RAMP) is a PCR-based marker which uses a combination of two classes of markers: Simple sequence repeat (SSR) and Random amplified DNA polymorphism (RAPD) markers. RAMP has been demonstrated to be a potentially valuable molecular marker for the study of genetic relationships in cultivated plant species. The objective of this study was to optimize the...
