“…Huge amounts of DNA barcode data are now available, providing invaluable insights for understanding species’ boundaries, community ecology and trophic interactions in ecology and evolution (Joly et al., ; Kress, ; Valentini et al., ). Furthermore, the technology is gradually gaining popularity in such fields as forensic identification (Ferri et al., ), authentication of medicinal herbs (Chen et al., ) and timber identification (Dormontt et al., ). However, genetic variation occurs, often abundantly, within species and populations, and especially across the distribution range of particularly of widespread taxa (Avise, ).…”

Rapid and accurate identification of endangered species is a critical component of biosurveillance and conservation management, and potentially policing illegal trades. However, this is often not possible using traditional taxonomy, especially where only small or preprocessed parts of plants are available. Reliable identification can be achieved via a comprehensive DNA barcode reference library, accompanied by precise distribution data. However, these require extensive sampling at spatial and taxonomic scales, which has rarely been achieved for cosmopolitan taxa. Here, we construct a comprehensive DNA barcode reference library and generate distribution maps using species distribution modelling (SDM), for all 15 Taxus species worldwide. We find that trnL-trnF is the ideal barcode for Taxus: It can distinguish all Taxus species and in combination with ITS identify hybrids. Among five analysis methods tested, NJ was the most effective. Among 4,151 individuals screened for trnL-trnF, 73 haplotypes were detected, all species-specific and some population private. Taxonomical, geographical and genetic dimensions of sampling strategy were all found to affect the comprehensiveness of the resulting DNA barcode library. Maps from SDM showed that most species had allopatric distributions, except T. mairei in the Sino-Himalayan region. Using the barcode library and distribution map data, two unknown forensic samples were identified to species (and in one case, population) level and another was determined as a putative interspecific hybrid. This integrated species identification system for Taxus can be used for biosurveillance, conservation management and to monitor and prosecute illegal trade. Similar identification systems are recommended for other IUCN- and CITES-listed taxa.

“…Apart from authentication of traded medicinal plants, DNA barcoding also finds application in biodiversity monitoring, conservation impact assessment, monitoring of illegal trading, forensic botany, etc. (Ferri et al, 2015;Nithaniyal et al, 2014;Verma and Goswami, 2014).…”

biological reference material herbal barcode library. SummaryThe past couple of decades have witnessed global resurgence of herbal-based health care. As a result, the trade of raw drugs has surged globally. Accurate and fast scientific identification of the plant(s) is the key to success for the herbal drug industry. The conventional approach is to engage an expert taxonomist, who uses a mix of traditional and modern techniques for precise plant identification. However, for bulk identification at industrial scale, the process is protracted and time-consuming. 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 cryptic species. For herbal plant identification, matK, rbcL, trnH-psbA, ITS, trnL-F, 5S-rRNA and 18S-rRNA have been used as successful DNA barcodes. Emerging advances in DNA barcoding coupled with next-generation sequencing and high-resolution melting curve analysis have paved the way for successful species-level resolution recovered from finished herbal products. Further, development of multilocus strategy and its application has provided new vistas to the DNA barcode-based plant identification for herbal drug industry. For successful and acceptable identification of herbal ingredients and a holistic quality control of the drug, DNA barcoding needs to work harmoniously with other components of the systems biology approach. We suggest that for effectively resolving authentication challenges associated with the herbal market, DNA barcoding must be used in conjunction with metabolomics along with need-based transcriptomics and proteomics.

“…All these examples reinforce the value of botanical evidence in solving Brazilian criminal caseworks. Lastly, with the political movements of the Brazilian Forensics aiming to become an independent organ of public safety 31 , as well as the increase in number of case studies and specific literatures 1,9,[32][33][34][35][36] , lies a great opportunity to include the topic in the police academy. The segregation of the Forensic Science (forensic scientists) from higher Brazilian organs of public safety at a constitutional level brings advantages, such as the management of forensic units by career professionals-which are the most suitable professionals in understanding the actual demand of the organs.…”
