DNA barcoding: an efficient technology to authenticate plant species of traditional Chinese medicine and recent advances

Chinese Medicine, 2022
Traditional Chinese medicine (TCM) plays an important role in the global traditional health systems. However, adulterated and counterfeit TCM is on the rise. DNA barcoding is an effective, rapid, and accurate technique for identifying plant species.

VIP Barcoding: Composition vector-based software for rapid species identification based on DNA barcoding

, 2014
Species identification based on short sequences of DNA markers, that is, DNA barcoding, has emerged as an integral part of modern taxonomy. However, software for the analysis of large and multilocus barcoding data sets is scarce.

Fast phylogenetic DNA barcoding [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2008
We present a heuristic approach to the DNA assignment problem based on phylogenetic inferences using constrained neighbour joining and non-parametric bootstrapping. We show that this method performs as well as the more computationally intensive full Bayesian approach in an analysis of 500 insect DNA sequences obtained from GenBank.

DNA Barcoding: Promise and Pitfalls

PLoS Biology, 2004
In this issue of PLoS Biology, Hebert et al. (2004) have set out to test the resolution and performance of “DNA barcoding,” using a single mtDNA gene, cytochrome c oxidase I (COI), for a sample of North American birds. Before turning to details of this study, it is useful as context to consider the following questions: What is DNA barcoding, and what ...

Leveraging machine learning and citizen science data to describe flowering phenology across South Africa

Plants, People, Planet
Societal Impact Statement Recent shifts in flowering times are an index of, and a response to, human driven climate change. However, most information on these flowering changes is heavily skewed to the northern hemisphere.
