DNA barcoding is a method of species identification using a short section of DNA from a specific gene or genes. The premise of DNA barcoding is that by comparison with a reference library of such DNA sections (also called "sequences"), an individual sequence can be used to uniquely identify an organism to species, just as a supermarket scanner uses the familiar black stripes of the UPC barcode ...

Pollen DNA barcoding is the process of identifying pollen donor plant species through the amplification and sequencing of specific, conserved regions of plant DNA. Being able to accurately identify pollen has a wide range of applications though it has been difficult in the past due to the limitations of microscopic identification of pollen.
The key concept for barcoding macroinvertebrates, is proper selection of DNA markers (DNA barcode region) to amplify appropriate gene regions, using PCR techniques. The DNA barcode region needs to be ideally conserved within a species, but variable among different (even closely related) species and therefore, its sequence should serve as a ...
Optical mapping [1] is a technique for constructing ordered, genome-wide, high-resolution restriction maps from single, stained molecules of DNA, called "optical maps". By mapping the location of restriction enzyme sites along the unknown DNA of an organism, the spectrum of resulting DNA fragments collectively serves as a unique "fingerprint" or "barcode" for that sequence.
The DNA barcoding of animals (and specifically of bats) is used as an example in the diagram at the right and in the discussion immediately below. First, suitable DNA barcoding regions are chosen to answer some specific research question. The most commonly used DNA barcode region for animals is a segment about 600 base pairs long of the ...
DNA barcoding of cyanobacteria can be applied in various ecological, evolutionary and taxonomical studies. Some examples include assessment of cyanobacterial diversity and community structure, [ 34 ] identification of harmful cyanobacteria in ecologically and economically important waterbodies [ 35 ] and assessment of cyanobacterial symbionts ...
Fungal DNA barcoding is the process of identifying species of the biological kingdom Fungi through the amplification and sequencing of specific DNA sequences and their comparison with sequences deposited in a DNA barcode database such as the ISHAM reference database, [1] or the Barcode of Life Data System (BOLD). In this attempt, DNA barcoding ...
