PREMISE OF THE STUDY PCR amplification of the matK barcoding region is often difficult when dealing with multiple angiosperm families. We developed a primer cocktail to amplify this region efficiently across angiosperm diversity. METHODS AND RESULTS We developed 14 matK primers (seven forward, seven reverse) for multiplex PCR, using sequences available in GenBank for 178 taxa belonging to 123...
The deep sequencing of 16S rRNA genes amplified by universal primers has revolutionized our understanding of microbial communities by allowing the characterization of the diversity of the uncultured majority. However, some universal primers also amplify eukaryotic rRNA genes, leading to a decrease in the efficiency of sequencing of prokaryotic 16S rRNA genes with possible mischaracterization of...
A universal restriction site-free cloning method has been developed to precisely insert a DNA fragment into a vector at any desired location without altering any nucleotide(s) in either the DNA fragment or the vector. The technique employs two pairs of chimeric primers, each containing a ribonucleotide. One pair of primers is used to amplify a target DNA fragment and another is used to prepare ...
Background: Meat species adulteration has become a problem of concern. This study aimed to compare two previously published multiplex Polymerase Chain Reaction (PCR) methods for meat species authentication. Methods: The primers used in the first multiplex PCR involved species-specific reverse primer for sheep, goat, cattle, pig, and donkey with universal forward primer. In the second multiple...
