This study was accomplished to detect variation generated through eposure of fenugreek (trigonella foenum-graecum L.) seeds seven gamma irradiation doses (0,25,50,100,150,300 and 400) GY by using twenty RAPDs primers as molecular marker ,results indicated that OPA-14 ,OPC-19 OPH-01success in giving five treatments a unique fingerprint. Molecular size amplicon ranged between 2913 bp produced pri...

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...

Thirty-three strains of Cryptococcus neoformans were isolated from clinical specimens, including specimens from AIDS patients in Brazil, and were classified into two serotypes; we detected 31 and 2 strains of serotypes A and B, respectively. Random amplified polymorphic DNA (RAPD) fingerprint pattern analyses of these strains of serotypes A and B showed that the patterns were similar for strain...

Fifteen serotypes of E. coli isolated from poultry were subjected to RAPD-PCR using eight oligonucleotide random primers. Amplification with each of the primers resulted in generation of different DNA fingerprinting profile with varied number of bands. Dendrogram based generation of clustering of E. coli serotypes showed two major clusters. The polymorphic amplicons served as markers for E. col...

Disease susceptibility and genetic variability in 10 eggplant genotypes were studied after inoculating Phomopsis vexans under confined field conditions. Random amplified polymorphic DNA (RAPD) markers were used to assess genetic variation and relationships among eggplant genotypes. The disease index of leaves ranged 0.208-13.79%, while fruit infection ranged 2.15-42.76%. Two varieties, Dohazari...

In this study, we report a simple procedure for developing and using new types of polymerase chain reaction (PCR) primers, named ‘‘high-frequency oligonucleotides–targeting active genes’’ (HFO-TAG). The HFOTAG primers were constructed by first using a ‘‘practical extraction and report language’’ script to identify oligonucleotides (8, 9, and 10 bases) that exist in high frequency in 4700 expres...

the effect of sub culturing frequencies and different cytokinins (benzyl amino purine (bap), 2-isopentenyl adenine (2ip) on genetic stability of micropropagated shoots from olive plant were investigated by using physiological traits and random amplified polymorphic dna (rapd) markers. axillary buds of the olive (cv. dezful) plants were cultured and subcultured in dkw medium, supplemented with b...

PCR-based fingerprinting using random amplified polymorphic DNA (RAPD) has been used widely for genome identification. In this study, 13 Salmonella Typhi strains were isolated from typhoid patients from Aswan, Cairo, Fayoum, and Monofya Governorates of Egypt. The isolates, along with three reference strains, i.e., O901, H901, and Ty2 were subjected to whole genome typing by RAPD PCR. Three RAPD...

The random amplified polymorphic DNA (RAPD) technique has been used widely for purposes such as the construction of linkage maps, QTL analysis, evaluation of genetic diversity, and parentage tests. However, some minor bands of RAPD display a low reproducibility and low reliability. We describe a simple and efficient method for making minor RAPD bands clearer. The first step of this method is to...

A study was conducted to investigate the relationship between the presence of localized bacterial infection and lameness in broiler fowl (Gallus gallus domesticus). Isolation of bacteria from the proximal femur, proximal tibia, and tibiotarsus from broilers with lameness revealed a probable association between lameness and the presence of Staphlylococcus aureus. Other potential pathogens, inclu...
