Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of 46 barley accessions, including 27 landraces of H. vulgare ssp vulgare (HV), 6 accessions of H. vulgare ssp. spontaneum (HS) and 13 accessions of H. vulgare ssp. agriocrithon (HA), from west China. A high level of polymorphism was fo...

PURPOSE The aim of this study was to compare the asymmetrical light reflex of the control subjects and patients with optic nerve disease and to evaluate the relationships among the relative afferent pupillary defect (RAPD), visual acuity (VA), central critical fusion frequency (CFF), ganglion cell complex thickness (GCCT), and circumpapillary retinal nerve fiber layer thickness (cpRNFLT) using ...

In the present study, 20 sandalwood (Santalum album L.) genotypes were characterized using RAPD, ISSR and SSR markers. Twenty-five RAPD and twenty-one ISSR primers that generated clear and reproducible banding patterns amplified 225 and 208 bands, respectively, among 20 sandalwood genotypes. Out of 225, 181 (83.13 %) RAPD bands were polymorphic while out of 208, 156 (75.77 %) ISSR bands were po...

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...

The efficacy of random primer-pair arrays compared to conventional RAPD method with a single decamer primer was evaluated using DNA from two species of Cucumis. The banding patterns of amplicons revealed enhanced utility of primer-pair arrays over conventional RAPDs, producing more bands and a higher degree of polymorphism, both at intra- and inter-specific levels. Amplification produced by bot...

In this study a total of 16 Fusarium verticillioides strains isolated from corn feed samples were characterized by fumonisin (FB) production and random amplified polymorphic DNA (RAPD). All the strains produced FB1 and FB2 with levels ranging from 2.41 to 3996.36 μg/g, and from 1.18 to 1209.91 μg/g, respectively. From the 16 F. verticillioides strains, four were identified as low (3.59 to 1289....

Bunias orientalis and Erigeron annuus are two alien herbal plant species invading native ecosystems in Lithuania. Both species have similar introduction and invasion history but differ in their life history traits and strategies of reproduction. We used random amplified polymorphic DNA (RAPD) data to compare the genetic diversity in invasive populations of these species. 42 RAPD bands were iden...

Mycoplasma bovis is an important veterinary pathogen causing pneumonia, arthritis, and mastitis in infected cattle. We investigated the genetic diversity of 53 isolates collected in the United Kingdom between 1996 and 2002 with pulsed-field gel electrophoresis (PFGE), amplified fragment length polymorphism (AFLP), and random amplified polymorphic DNA (RAPD) analysis. In addition, the influence ...

The obligatory human pathogen, Mycobacterium tuberculosis, is the most important etiological factor of tuberculosis. Unfortunately, there is little information about genetic diversity of this pathogen. The main aim of this research was the estimation of genetic diversity of M. tuberculosis on the basis of various categories of DNA markers. The genome of 32 strains were scanned by DNA markers su...

One hundred and forty-seven Salmonella serotype Typhimurium strains isolated in three provinces in the midwest of Spain were studied. Of these, 93.6% were drug resistant. There were two predominant resistance phenotypes: 43 isolates (29.3%) were resistant to amoxicillin, tetracyclines, chloramphenicol, streptomycin and sulphamethoxazole and 27 isolates (18.4%) to amoxicillin, amoxicillin/clavul...
