From fruiting bodies of L. edodes strain L-54, single-spore isolates (SSIs) were collected. Two parental types of L-54 were regenerated via monokaryotization. By means of random-amplified polymorphic DNA (RAPD), DNA samples from L-54, its two parental types, and 32 SSIs were amplified with arbitrary primers. Dedikaryotization was demonstrated, and 91 RAPD-based molecular markers were generated....

Classification and differentiation of Bacillus anthracis isolates by genetic markers play an important role in anthrax research. We used a PCR based method--Random Amplification of Polymorphic DNA (RAPD)--to identify genetic markers in B. anthracis strains. Twenty-five differential genetic markers were identified which divided the strains into five different groups. Three selected RAPD-markers ...

Relative afferent pupillary defects (RAPD) were detected in 32.3% of patients with amblyopia by a modification of the swinging flashlight test and the synoptophore. After consideration of various clinical investigations the significant factors identified in patients showing a RAPD were: anisometropia, early age of onset where strabismus was present, level of visual acuity following treatment, l...

Trichophyton rubrum is an important cause of dermatomycoses. Molecular strain typing methods have recently been developed to address questions about epidemiology and source of relapse following treatment. This report describes the application of RAPD for molecular strain differentiation of this fungus utilizing the primers 1- (5'-d[GGTGCGGGAA]-3') and 6- (5'-d[CCCGTCAGCA]-3'). A total of five R...

Random amplified polymorphic DNA (RAPD) analysis was adapted for genomic identification of cell cultures and evaluation of DNA stability in cells of different origin at different culture passages. DNA stability was observed in cultures after no more than 5 passages. Adipose-derived stromal cells demonstrated increased DNA instability. RAPD fragments from different cell lines after different num...

Genetic and epigenetic changes (DNA methylation) in the mother plants of somatic hybrids (1st cycle) and their regenerants (30th cycles sub-cultured) were analyzed using methylation-sensitive ISSR and RAPD markers. ISSR and RAPD profiles and their cluster analyses based on the Jaccard’s similarity coefficient revealed 100% genetic similarity among the mother plant and their regenerants. While f...

ABSTRACT Collections of Puccinia triticina, the wheat leaf rust fungus, were obtained from Great Britain, Slovakia, Israel, Germany, Australia, Italy, Spain, Hungary, South Africa, Uruguay, New Zealand, Brazil, Pakistan, Nepal, and eastern and western Canada. All single-uredinial isolates derived from the collections were tested for virulence polymorphism on 22 Thatcher wheat lines that are nea...

Eight hundred Erysipelothrix strains isolated between 1992 and 2002 from swine with erysipelas in Japan were serotyped. Thirty-seven, 47, 73, and 643 strains were isolated from animals with acute septicemia, urticaria, chronic endocarditis, and chronic arthritis, respectively, of which 381, 146, 254, and 19 isolates belonged to serotypes 1a, 1b, and 2b and other serotypes, respectively. All ser...

Kumar A, Verma N. 2012. A comparative phylogenetic analysis of medicinal plant Tribulus terrestris in Northwest India revealed by RAPD and ISSR markers. Biodiversitas 13: 107-113. Several DNA marker systems and associated techniques are available today for fingerprinting of plant varieties. A total of 5 RAPD and 8 ISSR primers were used. Amplification of genomic DNA of the 6 genotypes, using RA...

Due to advances in molecular biology techniques, large numbers of highly informative DNA markers have been developed for the identification of genetic polymorphism. 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 markers are amplificatio...
