A few candidate genes have been found in the chloroplast genome, the most promising being maturase K gene (matK) by itself or in association with other genes.For land plants the core DNA barcode markers are two sections of coding regions within the chloroplast, part of the genes, rbcL and matK. In order to create high quality databases, each plant that is DNA barcoded needs to have a herbarium voucher that accompanies the rbcL and matK DNA sequences.DNA barcoding is 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 mitochondrial cytochrome oxidase 1 (COX1) gene proposed by Hebert et al. (2003) is the most commonly used marker.
Which DNA barcode is currently used in 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. In order to create high quality databases, each plant that is DNA barcoded needs to have a herbarium voucher that accompanies the rbcL and matK DNA sequences.

What are some important applications of plant DNA barcoding?
DNA barcoding has many applications in various fields like preserving natural resources, protecting endangered species, controlling agriculture pests, identifying disease vectors, monitoring water quality, authentication of natural health products and identification of medicinal plants.
How reliable does the rbcL gene work as a barcode for identifying plant species?
The success rates of species identification of the four fragments were higher than 41.00% (rbcL: 41.50% ± 2.81%, matK: 42.88% ± 2.59%, trnH-psbA: 46.16% ± 5.11% and ITS: 47.20% ± 5.76%), demonstrating that these fragments have potentiality in species identification.
Why is rbcL used?
The rbcL gene is a useful barcode because it codes for part of the key photosynthesis enzyme ribulose bisphosphate carboxylase (RuBisCo), so it is present in virtually all plant species. One section of its DNA sequence is very variable between species, making it ideal for DNA barcoding.
What is next generation sequencing technology?
Next-generation sequencing (NGS) is a massively parallel sequencing technology that offers ultra-high throughput, scalability, and speed. The technology is used to determine the order of nucleotides in entire genomes or targeted regions of DNA or RNA.
What makes a good DNA barcode?
To be practical as a DNA barcode a gene region must satisfy three criteria: (i) contain significant species-level genetic variability and divergence, (ii) possess conserved flanking sites for developing universal PCR primers for wide taxonomic application, and (iii) have a short sequence length so as to facilitate …

What gene is used to obtain barcoding sequences for animals?
A region of the mitochondrial gene COI (cytochrome c oxidase subunit I) is used for barcoding animals. COI is involved in the electron transport phase of respiration. Thus, many genes used for barcoding are involved in the key reactions of life: storing energy in carbohydrates and releasing it to form ATP.
Why is mitochondrial DNA used for barcoding?
A barcode from the mitochondrial (mt) genome should represent the most effective single-locus marker because of it smaller population size relative to the nuclear genome, which increases the overall concordance between the gene tree and the underlying species tree [20,21].
What problems could DNA barcoding solve?
Among many other things, barcoding could help remove illegal fish and timber from global markets, slow the spread of invasive pests, reduce bird-plane collisions, and uncover the hideouts of medically-important mosquito species.
What is the difference between Metabarcoding and metagenomics?
In brief, metagenomics could be defined as the characterization of the vast number of genomes present in an environmental sample, using both a taxonomical and a functional analytical approach. DNA metabarcoding, on the other hand, principally focuses on taxonomically describing the species present within a sample.

Can plants be barcoded like animals?
2. Standard plant barcodes. There is no single plant barcode that matches the universality and resolving power of Cytochrome Oxidase (C01) in animals [2].
What is trnH psbA gene?
Barcode trnH-psbA makes for a good candidate for large-scale DNA barcoding of forage legumes and some grasses, such as C. cristatus, D. glomerata and T. flavescens (Table 3). However, further work is needed to produce reference sequences in more forage species and cultivars.
What is DNA Metabarcoding?
DNA metabarcoding is a cutting-edge molecular technique that resembles DNA barcoding in that it targets a specified gene and obtains short genetic sequences for identification. However, this technique sequences hundreds to thousands of organisms at one time rather than focusing on a single unique individual.
What is rbcL in plants?
The rbcL gene is the barcode DNA for plant species. Ternate Island is one of clove plantation center in North Maluku. The diversity and productivity of cloves on the Ternate island known since in earlier times.
What is Sanger DNA sequencing?
Sanger sequencing, also known as the “chain termination method”, is a method for determining the nucleotide sequence of DNA. The method was developed by two time Nobel Laureate Frederick Sanger and his colleagues in 1977, hence the name the Sanger Sequence. To review the general structure of DNA, please see Figure 2.
Where is rbcL located?
RbcL gene is located in the large single copy region of chloroplast genome [43, 44].
Which sequencing technology is the best?
Considerations for DNA sequencing
Currently, second-generation NGS technologies are the most commonly used approach because they remain the fastest and the cheapest form of gene sequencing.
How does Roche 454 sequencing work?
Roche 454 sequencing can sequence much longer reads than Illumina. Like Illumina, it does this by sequencing multiple reads at once by reading optical signals as bases are added. As in Illumina, the DNA or RNA is fragmented into shorter reads, in this case up to 1kb.
What is shotgun DNA sequencing?
Shotgun Sequencing
Shotgun sequencing is a laboratory technique for determining the DNA sequence of an organism’s genome. The method involves randomly breaking up the genome into small DNA fragments that are sequenced individually.
Why is PCR used for DNA barcoding?
DNA barcoding involves the production of PCR amplicons from particular regions to sequence them and these sequence data are used to identify or “barcode” that organism to make a distinction from other species (Lebonah et al., 2014).

Why is CO1 the animal barcode marker?
The mitochondrial CO1 gene region (cytochrome c oxidase 1) has become the standard genetic marker for a broad range of animal phyla since it has been promoted as the “universal” DNA barcoding marker for Metazoa [11]. The CO1 gene bears some characteristics making it particularly effective for evolutionary studies.
What are some of the limitations of DNA barcoding?
For DNA in soil, even less is known about distribution, quantity or quality. The major limitation of the barcoding method is that it relies on barcode reference libraries for the taxonomic identification of the sequences. The taxonomic identification is accurate only if a reliable reference is available.
