Major diseases in grafted cacti have been reported and Fusarium oxysporum, Bipolaris cactivora, Phytophthora spp. and Collectotrichum spp. are known as causal pathogens. These pathogens can lead to plant death after infection. Therefore, some European countries have quarantined imported cacti that are infected with specific fungal pathogens. Consequently, we developed PCR detection methods to i...

PrimeArray is a Windows program that computes oligonuceotide primer pairs for genome-scale gene amplification by the Polymerase Chain Reaction (PCR). The program supports the automated extraction of coding sequences (CDS) from various input-file formats and allows highly automated primer pair-optimization.

in this study, we investigated the relationship between the genetic polymorphism of growth differentiation factor 9 (gdf9) genes and the litter size in 384 individuals of five breeds of black goats. four pairs of primers were designed to detect single nucleotide polymorphism of gdf9 gene in goats by pcr-sscp. the least square was used to analyze the relation between different genotypes and the ...

BACKGROUND Robust designs of PCR-based molecular diagnostic assays rely on the discrimination potential of sequence variants affecting primer-to-template annealing. However, for accurate quantitative PCR (qPCR) assessment of gene expression in populations with gene polymorphisms, the effects of sequence variants within primer binding sites must be minimized. This dichotomy in PCR applications p...

The level of polymorphism among twelve selected progenies of Gymnema sylvestre was investigated through AFLP markers by multiplexing PCR reactions using 64 (8x8) primer combinations. Fourteen primer combinations were selected as the most suitable combination for G. sylvestre. Analysis of the 12 progenies with these 14 primer pairs produced 1689 fragments of which 972 (57.5%) were polymorphic an...

Common kilka Clupeonella cultriventris (Nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the Caspian Sea. A total of 60 specimens of adult common kilka were sampled from two seasons. Fifteen pairs of microsatellites previously developed for A.sapidissima, C. pallasi, C.harengus, and S. pilchardus were tested for ...

Efficiency and specificity of PCR amplification is dependent on several parameters, such as amplicon length, as well as hybridization specificity and melting temperature of primer oligonucleotides. Primer design is thus of critical importance for the success of PCR experiments, but can be a time-consuming and repetitive task, for example when large genomic regions are to be scanned for the pres...

The polymerase chain reaction (PCR) is one of the most rapidly expanding methods in molecular biology. Although the range of applications of PCR is very broad, the key points for successful performance remain the careful selection of optimal primers and the proper determination of the temperature conditions of the reaction. The program presented here, 'Primer Master', has been developed to assi...

We describe polymerase chain reaction primer pairs and reaction conditions for amplification of 15 microsatellite loci from eastern hemlock (Tsuga canadensis). The primers were tested on 23 individuals from a natural population in southwestern North Carolina, USA. These primers yielded an average of 5.9 alleles per locus (range of 2-14), an average observed heterozygosity of 0.45 (range 0.14-0....
