DNA barcoding is currently an effective and widely used tool that enables rapid and accurate identification of plant species. TheOrchidaceaeis the second largest family of flowering plants, with more than 700 genera and 20,000 species distributed nearly worldwide. The accurate identification ofOrchidsn...

DNA barcoding, on the other hand, offers an alternative and feasible taxonomic tool box for rapid and robust species identification. For the success of DNA barcode, the barcode loci must have sufficient information to differentiate unambiguously between closely related plant species and discover new ...
DNA barcoding is a technique for identifying species by analyzing short DNA regions, such as genetic markers. The length of the DNA barcode marker should be long enough to obtain sufficient taxonomic information, but short enough to meet the constraints of sequencing resources. For instance, the ...
Among the plant species of the New World, black locust (Robinia pseudo- acacia L.), a tree of the family Fabaceae native to Appalachia in the Eastern United States, is notable. In addition, we identified crop species largely grown by farmers and common in many agriculture systems of the ...
It can be used to indentify unknown species and discover new species by scanning and analyzingDNA fragments. The advantages of this technology stand out when traditional taxonomy is challenged bylife -stage transformations of their specimen, especially in fungi. Many scientists have beenworking on se...

Only 10 species had fewer than three sequences. This database provides users with the following three functions: 1 Basic information on each crude drug recorded in the JP; 2 Herbal material DNA barcoding identification; 3 The standard operating procedure (SOP) from sampling to data analysis....
DNA barcoding, usually based on the mitochondrial COI fragment1, has been extensively used to discriminate between closely related species, to identify new, cryptic or invasive species and to assess biodiversity across many animal phyla1. The rule-of-thumb in DNA barcoding is that interspecific COI...
