Current metabarcoding studies aiming to characterize microbial communities generally rely on the amplification and sequencing of relatively short DNA regions. For fungi, the internal transcribed spacer (ITS) region in the ribosomal RNA (rRNA) operon has been accepted as the formal fungal barcode. Despite an increasing number of fungal metabarcoding studies, the amplification efficiency of prime...

Real-time reverse transcriptase PCR (rRT-PCR) assays have greatly contributed to the detection, control, and prevention of the pandemic influenza A/H1N1 2009 virus. To improve the rRT-PCR assays for detection of pandemic influenza A/H1N1 2009 virus, we evaluated the sensitivity, specificity, and performance of 12 rRT-PCR primer-probe sets [SW (a) to SW (l)] using a panel of virus strains and cl...

A PCR-DGGE primer pair, Tyl2F-Tyl4R, specific to plant parasitic and fungivorous nematodes was designed based on the 18S rRNA gene. The results of community analysis using the primers showed that they are specific to the order Tylenchida. This primer pair detected species belonging to Tylenchida with high sensitivity and high resolution. The number of detected species of plant parasitic and fun...

SUMMARY ExPrimer is a web-based computer program to design primers mainly from a specified exon-exon junction (E-E-jn) of a gene of interest. The tool suggests the optimum primer-pair(s) of which the right (reverse) primer represents a particular E-E-jn of the mRNA. The 'product length' decides the location of the left primer. The results also include all other primer pairs considered and their...

An annual seasonal cycle of composition of a bacterioplankton community in an oligotrophic coastal system was studied by denaturing gradient gel electrophoresis (DGGE) using five different primer sets. Analysis of DGGE fingerprints showed that primer set 357fGC-907rM grouped samples according to seasons. Additionally, we used the set of 16S rRNA genes archived in the RDPII database to check the...

We have compared the efficacies of three general primer pairs for the detection of human papillomavirus (HPV) DNA in formaldehyde-fixed paraffin-embedded carcinomas. The use of these primer pairs leads to underestimates of the HPV prevalence (GP5/6, 61.1%; CPI/IIG, 57.4%; MY09/11, 46.9%; combined, 72.8%). The efficacy of each primer pair seemed to be inversely correlated to the length of the am...

To facilitate the analysis of mitochondrial DNA (mtDNA) control region sequences from highly degraded skeletal remains, a modified mini-primer set was designed to overcome the limitations of the Armed Forces DNA Identification Laboratory (AFDIL) mini-primer set. This modified mini-primer set is less affected by nucleotide variability and PCR amplification conditions than the AFDIL mini-primer s...

In recent years, PCR-based pyrosequencing of 16S rRNA genes has continuously increased our understanding of complex microbial communities in various environments of the Earth. However, there is always concern on the potential biases of diversity determination using different 16S rRNA gene primer sets and covered regions. Here, we first report how bacterial 16S rRNA gene pyrotags derived from a ...
