چکیده
enes with 3 What characterises DNA barcoding is the attempt to standardise the molecular approach by focusing on one or a few g appropriate levels of among-species divergence, and to secure global accessibility to a common database. Additionally, although one gene, cytochrome oxidase I (COI), has proven to be informative across diverse taxa, the aim of DNA barcoding has not been to identify a single common gene, but rather to maximise standardisation across related taxa to ensure high comparability. DNA barcoding is essentially a practical tool that can be applied to compare a target DNA sequence with a reference DNA sequence that may confirm species identity or generate alternative hypotheses of species delineation. It is crucial therefore to appreciate that rather than replacing conventional approaches to taxonomy, which rely heavily on ecological, morphological and behavioural characteristics, DNA barcoding can in many cases render the Linnaean system more accessible. A recent cover of Nature illustrating a modern-age Linnaeus wearing a contemporary naturalist’s outfit and holding a barcode in his hand could not be more paradigmatic.

DNA Barcoding: a new tool with wide array of applications
DNA barcoding is a new term introduced in to scientific literatures by Hebert and coworkers almost a decade ago. The concept of barcoding alone is well-known to the public: a series of black bars printed on many commercial products (Universal Product Code), which are used to distinguish different products. Advances made in molecular biology and molecular techniques late 20th century e.g. sequen...
متن کاملThe MexBOL initiative.
In 2005, Mexican researchers were invited to participate in the Barcode of Life Initiative. A few researchers showed interest in the initiative then, and in 2007, Paul Hebert from the University of Guelph in Canada came to Chetumal and Mexico City and presented his proposal to the scientific community of Mexico. Initially there were mixed feelings, especially because of the complexities of plan...
متن کاملOn Time Fractional Modifed Camassa-Holm and Degasperis-Procesi Equations by Using the Haar Wavelet Iteration Method
The Haar wavelet collocation with iteration technique is applied for solving a class of time-fractional physical equations. The approximate solutions obtained by two dimensional Haar wavelet with iteration technique are compared with those obtained by analytical methods such as Adomian decomposition method (ADM) and variational iteration method (VIM). The results show that the present scheme is...
متن کاملPhylogenetic 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...
