PURPOSE This study investigated the correlation between the relative afferent pupillary defect (RAPD) and retinal nerve fiber layer thickness (RNFLT) in optic neuropathy. METHODS RAPD assessment was performed using a log unit neutral density filter bar. Spectral domain optical coherence tomography RTVue-100 (Optovue) was used to examine the subjects. The optic nerve head pattern (ONH) was sub...

The use of random amplified polymorphic DNA from the polymerase chain reaction (RAPD-PCR) allows efficient construction of saturated linkage maps. However, when analyzed by agarose gel electrophoresis, most RAPD-PCR markers segregate as dominant alleles, reducing the amount of linkage information obtained. We describe the use of single strand conformation polymorphism (SSCP) analysis of RAPD ma...

Genetic variations of 15 Brahmi (Bacopa monnieri L.) accessions were evaluated using random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. During RAPD analysis, amplification of genomic DNA of the 15 accessions by 22 primers generated 197 fragments, of which 187 were polymorphic with an average of 8.95 bands per primer. The amplified products varied in size f...

Random amplification of polymorphic DNA (RAPD) analysis using the polymerase chain reaction proved a useful technique in the biodiversity analysis of microorganisms but may lack reproducibility in the poorly standardized methodology. In the present investigation, the RAPD technique was optimized for characterizing cyanobacterial isolates in order to ensure its reproducibility and discriminatory...

The usefulness of random amplification of polymorphic DNA (RAPD) analysis for typing Indian strains of M. tuberculosis was investigated. M. tuberculosis H37Rv, M. tuberculosis DT and 42 clinical isolates of M. tuberculosis were subjected to RAPD-PCR using 7 random decamer primers. All 7 primers were found to be differentiated and produced specific RAPD profiles. The polymorphic amplicons served...

A diploid Solanum clone 9507-04 was used to grow anther-derived plantlets that were putatively monoploid. Sixteen RAPD primers were used to observe the RAPD profiles from anther-donor and anther-derived materials. A total of 56 RAPD markers were scored and each marker was identified according to the primer’s designation and size (kilo base pairs) of the amplified fragment. Of 56 RAPD markers as...

The sodium dodecyl sulfate-polyacrylamide gel electrophoresis patterns of water-soluble proteins and the randomly amplified polymorphic DNA (RAPD) patterns of whole-cell lysates from 21 Aspergillus ustus isolates, including 11 reference strains and 10 patient and environmental strains from one hospital, were investigated. All isolates showed identical protein patterns. The RAPD assay discrimina...

Costus pictus, belonging to the family Costaceae, is one of the valuable medicinal plants with its anti-diabetic property. Despite ever-increasing demand from the pharmaceutical industry, this species is being less exploited at molecular level. Hence, an effort has been made in the present study to characterize the 15 accessions of C. pictus collected from different geographical regions of Indi...

The genetic diversity among 16 strains of Erwinia amylovora, chosen to represent different host plant origins and geographical regions, was investigated by RAPD analysis. One strain of Erwinia herbicola and one of Agrobacterium vitis were used as outgroups. Ninety-eight different RAPD fragments were produced by polymerase chain reaction amplification with six different 10-mer primers. RAPD band...

Twelve species belonging to six fungal genera were found to be associated with wheat (Triticum aestivum L.) grain samples collected from three main regions in Saudi Arabia. The most common genera (average frequency) were Aspergillus (14.3%), Fusarium (29.1%), Penicillium (9.3%), and Alternaria (8.2%). Nineteen isolates of Aspergillus flavus were screened for their ability to produce aflatoxins ...
