In the present study, marine crab Portunuspelagicus was screened with 17 primers and made to score polymorphism. The main emphasis of study assess genetic diversity at intra specific level among 3 accessions P. pelagicus species Gulf Mannarusing RAPD markers. analysis shows that there is a high polymorphism different accessions. From this it understood each location varied respect environmental...

in recent years, several plant species have been used as bioindicators, and several tests have been developed to evaluate the toxicity of the environmental contaminants. in this study, the root length and dna band pattern of root tips in maize (zea mays l.) seedlings were exposed at different concentration of cadmium pollutant (40 and 80 mg l−1). the results indicated that the root length of ma...

Sesame (Sesamum indicum L.) is an ancient oilseed crop known for its nutty seeds and high-quality edible oil. It is an unexplored crop with a great economic potential. The present study deals with assessment of genetic diversity in the crop. Twenty two RAPD and 18 SSR primers were used for analysis of the 47 different sesame accessions grown in different agroclimatic zones of India. A total of ...

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...

the genetic diversity of 40 tobacco (nicotiana tabacum l.) cultivars was analyzed using 12 issr primers. thecultivars were evaluated for 14 traits using a simple lattice design (7×7) with two replications. of 149 amplified bands, 142 (95.3%) were polymorphic. maximum and minimum bands were generated by primers ubc825 (17 bands and 94.11% polymorphic) and ubc824 (7 bands and 100% polymorphic), r...

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...

Grapevine (Vitis vinifera L.) is one of important economic fruit crops found in Salahaldin province \ Iraq. To examine the Molecular characterization and genetic relationships among nine grape varieties by using random amplified polymorphic DNA (RAPD) marker. Fifteen RAPD primers produced band (71, 56%), while two yielded monomorphic bands only. The size fragment ranged between 250-2700 bp, wit...

Impact assessment of contaminants in soil is an important issue in environmental quality study and remediation of contaminated land. A random amplified polymorphic DNA (RAPD) 'fingerprinting' technique was exhibited to detect genotoxin-induced DNA damage of plants from heavy metal contaminated soil. This study compared the effects occurring at molecular and population levels in barley seedlings...

We optimized RAPD techniques by increasing the length of RAPD primers and performing a strict screening of PCR annealing temperature to distinguish 60 sweet orange cultivars from the Research Institute of Pomology at the Chinese Academy of Agricultural Sciences. A new approach called cultivar identification diagram (CID) was used to improve the efficiency of RAPD markers for cultivar ident...
