DNA barcoding is commonly used for species identification. Despite this, there has not been a comprehensive assessment of the utility of DNA barcoding in crayfishes (Decapoda: Astacidea). Here we examined the extent to which local barcoding gaps (used for species identification) and global ...
Meta-barcodingMicrobiomeTaxonomyPyrosequencing16S rRNAIn recent years, thanks to the essential support provided by the Next-Generation Sequencing (NGS) technologies, Metagenomics is enabling the direct access to the taxonomic and functional composition of mixed microbial communities living in any environmental...
MT-COI is widely used for DNA barcoding as it has both conserved regions and segments with high divergence (Hebert et al. 2003). Recent work identified a segment of MT-COI capable of discerning wild and domestic goat and sheep taxa in Central Asia, making it an important addition for diet...
The success of parasitoids is in turn a clue to the previously unexplored diversity of their hosts, especially other Holometabola. Full species delimitation and description require more detail than DNA barcoding alone can provide; these are questions best answered by integrative methods that ...

Govindaraghavan and Li proposed that the entire plastid genome should to be used in the field of DNA barcoding (Govindaraghavan et al., 2012, Li et al., 2015). Sucher suggested the genomic fingerprinting can differentiate between individuals, species and populations, and is useful for the ...
11.8.2DNA barcoding DNA barcodingis a taxonomic method that uses a short genetic marker in an organism’s DNA to identify at the species level. Several loci have been suggested, but the mitochondrialcytochrome oxidase1 (COX1) gene proposed byHebertet al.(2003)is the most commonly used marker...
The most commonly used molecular markers for DNA barcoding are COI genes, which are located in the mitochondrial genome (mtDNA). The COI gene has been used for identification of different vertebrates and invertebrates (Tautz et al. 2002; Hebert et al. 2003; Kress et al. 2005; Ward et al....
DNA barcoding consists of two primary components: 1) a genetic sequence or barcode that is unique to a particular species, comparable to a commercial product's UPC code; and 2) an electronic database capable of providing the identity or name of a species by reading and matching its genetic ...
The validity of DNA barcoding relies heavily on the availability of a precise reference database, as it serves as the cornerstone of DNA barcoding. In this study, we constructed a comprehensive ITS2 matrix encompassing genuine NReR and their commonly found adulterants for the first time. This ma...
