Microsatellites occur in all plant genomes and provide useful markers for studies of genetic diversity and structure. Chloroplast microsatellites (cpSSRs) are frequently targeted because they are more easily isolated than nuclear microsatellites. Here, we quantified the frequency and uses of cpSSRs based on a literature review of over 400 studies published 1995-2013. These markers are an import...

The 16S rRNA gene of Haemobartonella felis was amplified by using universal eubacterial primers and was subsequently cloned and sequenced. Based on this sequence data, we designed a set of H. felis-specific primers. These primers selectively amplified a 1,316-bp DNA fragment of the 16S rRNA gene of H. felis from each of four experimentally infected cats at peak parasitemia. No PCR product was a...

The mosaic structure of the cagA gene has been suggested to affect Helicobacter pylori CagA-associated pathogenesis. An improved polymerase chain reaction assay allowed for a rapid and detailed molecular analysis of the cagA gene 3'-region in a single amplification step, followed by amplicon sequencing using universal M13 and T7 sequencing primers.

background: classical bacteriological detection of brucella species from food, and environment is routinely carried out based on morphological and biochemical characteristics. however, for increasing specificity and sensitivity of species identification methods, development of a molecular assay is necessary that was main aim of this study. methods: panel of some reference strains belonging to t...

The caption for Figure 5 reads: One-color SNV quantification. (A) Primers are designed with the single nucleotide variant at the 3′ end of the complementary region. Noncomplementary tails of varying lengths are then added to the 5′ end and amplified with a universal reverse primer. (B) 1:4 mixture of MUT/WT BRAF template amplified with mutant primers with the short tail and wild-type primers wi...

The alignment of the 28S gene of several species of Pezizales allowed to select two pairs of primers able to amplify the internal transcribed spacer region of ribosomal DNA in mycorrhizal fungi, such as truffles. The higher yield of the amplification product demonstrates a better annealing of the new primers to the rDNA, as compared to the universal primers internal transcribed spacer 1 and int...

Prokaryotic communities in pristine and oil-contaminated desert soil, seawater, and hypersaline coastal soil were analyzed using culture-dependent and culture-independent approaches. The former technique was the dilution-plating method. For the latter, total genomic DNA was extracted and the 16S rRNA genes were amplified using a universal bacterial primer pair and primer pairs specific for Acti...

We investigated the bacterial communities of nine Bartonella-positive fleas (n = 6 Oropsylla hirsuta fleas and n = 3 Oropsylla montana fleas), using universal primers, clone libraries, and DNA sequencing. DNA sequences were used to classify bacteria detected in a phylogenetic context, to explore community assembly patterns within individual fleas, and to survey diversity patterns in dominant li...

Fig. S1. Results of polymerase chain reaction (PCR) using universal primers targeting mycobacterium DNA: hsp65 short (hsp65S; 441 bp), long (hsp65L; ca.770 bp), rpoB short (rpoBS; ca.330bp), long (rpoBL; ca.450bp) genes and the 16S-23S spacer region (internal transcribed spacer (ITS); ca. 350 bp). Clear strong bands with hsp65L, rpoBS, and ITS primers proved the existence of mycobacteria DNA. I...
