This is in marked contrast to the multiple str approach used for identifying individuals within a species. Dna barcoding is a system for fast and accurate species identification. The ideal plant barcode needs to be amplifiable with only a single set of primers, so that it can be efficiently retrieved from any of the over 200,000 species of plants. Aquatic plant biodiversity and dna barcoding request pdf. It makes use of a short genome a barcode that evolves fast enough to differ between closely related species. In conclusion, rbcl and trnhpsba were the most suitable dna barcode fragments for species identification in mangrove plants. For land plants the core dna barcode markers are two sections of coding regions within the chloroplast, part of the genes, rbcl and matk. Here, we propose two dna regions for barcoding plants and provide an initial test of their utility. Dna barcoding the native flowering plants and conifers of. Dna barcoding involves the use of a single gene to identify a given species through the comparison of nucleotide sequences in the dna to that of the same gene in other species.

In plants, however, low substitution rates of mitochondrial dna have led to the search for alternative barcoding regions. Dna barcoding to the species level is sometimes difficult with a single barcode, as species may share identical barcodes. Dna barcoding analysis and phylogenetic relation of. In addition, in fungi these genes are subject to duplications. Largescale standardized sequencing of the mitochondrial gene co1 has made dna barcoding an efficient species identification tool in many animal groups 1.
