Free-living N2-fixing Frankia strains isolated from Casuarina sp. were investigated for genomic polymorphism. We used six 10-mer oligonucleotides as single arbitrary primers (AP) for the polymerase chain reaction (PCR) in order to amplify random DNA fragments in the genome of free-living Frankia strains. Agarose-gels of the amplified genomic DNA revealed that two of the six arbitrary primers sh...

Analogous to metagenomics, environmental transcriptomics (metatranscriptomics) retrieves and sequences environmental mRNAs from a microbial assemblage without prior knowledge of what genes the community might be expressing. Thus it provides the most unbiased perspective on community gene expression in situ. Environmental transcriptomics protocols are technically difficult since prokaryotic mRNA...

A very sensitive and specific method for the random amplification of whole DNA molecules and genomes ranging from 400 base pairs (bp) to 40 Megabase (Mb) is described. This simple, two step PCR (1-3) strategy utilizes tagged random primers that consist of a pool of all possible 3' sequences for binding to the target DNA and a constant 5' region for the detection of incorporated primers. As litt...

UNLABELLED PREMISE OF THE STUDY New microsatellite primers were developed for the diploid herb Anthyllis vulneraria. These primers will be used in upcoming studies focusing on random genetic variation, local adaptation, and phenotypic plasticity in alpine plants. • METHODS AND RESULTS The new primers were adjusted to separate PCR amplicons (70 to 170 bp) on precast Spreadex gels using hori...

Haplorchis taichui specific primers were designed using a high annealing temperature random amplified polymorphic DNA (HAT-RAPD) PCR method and 18 arbitrary primers (Operon Technologies) to generate polymorphic DNA profiles for 13 different parasites. The H. taichui specific fragment was screened. A 256 bp HAT-RAPD marker generated from OPP-11 primer specific for H. taichui was cloned and seque...

The usefulness of random amplified microsatellite polymorphism markers to study the genetic diversity and relationships among cultivars belonging to Prunus salicina and P. domestica and their wild relatives (P. insititia and P. spinosa) was investigated. A total of 226 of 234 bands were polymorphic (96.58%). The 226 random amplified microsatellite polymorphism markers were screened using 15 ran...

A total of 65 blood samples collected from Holstein cattle were employed for DNA extraction. Genomic DNA were amplified by means of random amplified polymorphic DNA (RAPD). One hundred and one random primers (Operon kits OPAA, OPAO, OPAV, OPC, OPE and OPA-06) were used for polymerase chain reactions (PCR). The PCR products were size fractionated by means of electrophoresis in agarose gel, trans...

The suitability of random amplified polymorphic DNA-PCR for the detection of differences between Mycobacterium malmoense strains was evaluated. With two of the 32 tested primers seven fingerprint patterns which proved excellent in distinguishing intraspecies variations of M. malmoense were obtained. The combination of the results obtained with the two primers permitted a clear separation of the...

Y alphoid primers in combination with Alu and LINEs primers generated new DNA fragments in polymerase chain reactions (PCR) on DNA from a Y-only somatic cell hybrid but not from X-only, 3-only, or 21-only hybrids. X alphoid primers used in a similar manner generated new DNA fragments from the X-only hybrid, and 1 of the primers (X2) also generated new DNA fragments on 3-only and 21-only hybrids...

RAPD is a simple dominant marker system widely used in biology. Effectiveness of RAPD can be improved by selecting and redesigning primers whose priming sites occur in target sequence(s) of gene or organism at optimum distance. We developed software that uses sequences of random decamer primers and nucleotide sequence(s) as two input files. It locates the priming sites in input sequences and ge...
