Methods for identifying species by using short orthologous DNA sequences, known as "DNA barcodes," have been proposed and initiated to facilitate biodiversity studies, identify juveniles, associate sexes, and enhance forensic analyses. The cytochrome c oxidase 1 sequence, which has been found to be widely applicable in animal barcoding, is not appropriate for most species of plants because of a much slower rate of cytochrome c oxidase 1 gene evolution in higher plants than in animals. We…

Utility of DNA Barcoding for Plant Biodiversity Conservation
TLDR
The region ITS2 showed better intra-species variation, followed by psbA-trnH, which reveals that the ITS2 region is able to distinguish all tested species of the plant kingdom, but evaluations of DNA barcodes have to be conducted for more species covering many genera to confirm the above results.
DNA barcoding methods for land plants.
TLDR
Results from the two chosen core plant DNA barcode regions rbcL and matK plus two supplementary regions trnH-psbA and internal transcribed spacer (ITS) (or ITS2) have demonstrated reasonable levels of species discrimination in both floristic and taxonomically focused studies.
DNA barcoding the floras of biodiversity hotspots
TLDR
Analysis of >1,000 species of Mesoamerican orchids, DNA barcoding with matK alone reveals cryptic species and proves useful in identifying species listed in Convention on International Trade of Endangered Species (CITES) appendixes.
The specific DNA barcodes based on chloroplast genes for species identification of Orchidaceae plants
TLDR
The DNA barcoding of 4 chloroplast genes were used to provide theoretical basis for species identification, germplasm conservation and innovative utilization of orchids and the standardized and accurate barcode information of Orchids is provided.
300,000 species to identify: problems, progress, and prospects in DNA barcoding of land plants
TLDR
Two DNA regions, the plastid trnH-psbA spacer and nuclear ribosomal ITS region, have been shown to have potential as an identification barcode for land plants, although with some significant drawbacks.
DNA barcoding in land plants: evaluation of rbcL in a multigene tiered approach
TLDR
Analysis of over 10 000 rbcL sequences from GenBank demonstrate that this locus could serve well as the core region, with sufficient variation to discriminate among species in approximate ranges, and a tiered approach wherein highly variable loci are nested under a core barcoding gene is proposed.
Evolutionary Analysis based on DNA Barcoding of Certain Aquatic Plants using rbcL Gene Sequences
TLDR
The findings showed that using rbcL gene sequences, majority of the samples, i.e. (90%) were identified at genus level but at species level only 10% identification was possible, which is significantly lower than the previous studies.
Searching for DNA barcodes in plants.
The utility of large scale standardized DNA sequencing and bioinformatics tools are now increasing in the area of plant systematics and evolution while a short DNA segment can be effectively used for
Multiple Multilocus DNA Barcodes from the Plastid Genome Discriminate Plant Species Equally Well
TLDR
Resolution to the contentious debate on plant barcoding should involve increased attention to practical issues related to the ease of sequence recovery, global alignability, and marker redundancy in multilocus plant DNA barc coding systems.
Land plants and DNA barcodes: short-term and long-term goals
TLDR
An assessment of how well current phylogenetic resources might work in the context of identification (versus phylogeny reconstruction) with two of the markers commonly sequenced in land plant phylogenetic studies, plastid rbcL and internal transcribed spacers of the large subunits of nuclear ribosomal DNA (ITS), finds that both of these DNA regions perform well.

The use of chloroplast DNA to resolve plant phylogenies: noncoding versus rbcL sequences.
TLDR
P pairwise comparisons among dicots and monocots for rbcL and two noncoding sequences of cpDNA show that these regions evolve faster (more than three times faster, on average) than rBCL, and that the trnL intron evolves at a rate that is the same as that of the intergenic spacer.
Identification of Birds through DNA Barcodes
TLDR
The finding of large COI sequence differences between, as compared to small differences within, species confirms the effectiveness of COI barcodes for the identification of bird species, and implies that a standard screening threshold of sequence difference could speed the discovery of new animal species.
The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis.
TLDR
The results of this study show that a survey using as few as three representative taxa can be predictive of the amount of phylogenetic information offered by a cpDNA region and that rate heterogeneity exists among noncoding cpDNA regions.
Chloroplast DNA phylogeny, reticulate evolution, and biogeography of Paeonia (Paeoniaceae).
TLDR
A refined hypothesis of species phylogeny of section Paeonia was proposed by considering the discordance between the nuclear and cpDNA phylogenies to be results of hybrid speciation followed by inheritance of cpDNA of one parent and fixation of ITS sequences of another parent.

To elucidate relationships at deep levels within Saxifragaceae we analyzed phylogenetically a data set of sequences for six DNA regions, four representing the chloroplast genome (rbcL, matK,
Evolution of Hedera (the Ivy Genus, Araliaceae): Insights from Chloroplast DNA Data
TLDR
The maternal parents of the polyploid species H. hibernica, H. iberica, and H. pastuchovii are identified on the basis of the comparison of the chloroplast DNA phylogeny and the ITS topology, and allopolyploidization playing a major part in the evolution of Hedera.
Deep-level diagnostic value of the rDNA-ITS region.
TLDR
The analysis of the deep-level phylogenetic signal in the highly conserved but short 5.8S and hypervariable ITS2 sequences indicates that ITS region sequences can diagnose organismal origins and phylogenetic relationships at many phylogenetic levels and provide a useful paradigm for molecular evolutionary study.

Biological identifications through DNA barcodes
TLDR
It is established that the mitochondrial gene cytochrome c oxidase I (COI) can serve as the core of a global bioidentification system for animals and will provide a reliable, cost–effective and accessible solution to the current problem of species identification.
