چکیده

this study pursued the molecular identification of fish species from processed products for human consumption which, a priori, belonged to nine species. dna barcoding using direct sequencing of about 650 bp of the mitochondrial gene cytochrome oxidase subunit i (coi) revealed incorrect labeling in the three alaska pollack samples (11% of all samples). substitution of fish species constitutes serious economic fraud, and our results increase concern regarding the trading of processed fish products in iran from both health and conservation points of view.

DNA barcoding for the identification of smoked fish products

Identification of fish fillets usually requires the application of a molecular tool because most of the morphological traits used in species identification are removed during the filleting process. Early molecular identification methods relied on protein electrophoresis that became recognized as an official method for fish fillet identification (AOAC, 1990; Tenge et al., 1993; Yearsley et al., ...

DNA barcoding Australia's fish species.

Two hundred and seven species of fish, mostly Australian marine fish, were sequenced (barcoded) for a 655 bp region of the mitochondrial cytochrome oxidase subunit I gene (cox1). Most species were represented by multiple specimens, and 754 sequences were generated. The GC content of the 143 species of teleosts was higher than the 61 species of sharks and rays (47.1% versus 42.2%), largely due t...

DNA Barcoding for Species Identification in Bamboos

DNA barcoding first came to the attention in 2003 when Paul Hebert’s research group at the University of Guelph published a paper titled ‘Biological identifications through DNA barcodes’. The basic principle behind DNA barcoding is based on the fact that small DNA sequences are capable of identifying different species as well as they are able to differentiate them. This technique deals with a n...

Phylogenetic Assessment of Some Species of Crocus Genus Using DNA Barcoding

DNA barcoding is a simple method for the identification of any species using a short genetic sequence from a standard genome section. The present study aimed at examining the nuclear and chloroplast diversity as well as the phylogenetic relationships of eight species of saffron including four spring-flowering and five autumn-flowering species from different parts of Iran, using the nuclear barc...
