- Abstract
DNA barcoding involves one or a few standardized short DNA segments to discriminate species. Comparing with the traditional methods, DNA barcoding has some advantages such as expanding species diagnoses to cover all the life stages of an organism, digitized discriminating process, quick and highly precise, requiring less taxonomic experience to discover a new species. DNA barcoding is now being widely utilized in biological sciences, including species identification in biodiversity monitoring, biological invasion, forensic contexts, food and medicinal market. After fifteen years of development, the researchers have achieved consensus on standard DNA barcodes in animal, plants and fungi, and has constructed the global DNA barcoding library. Now the evaluation of DNA barcoding has typically focused on two different perspectives. One is to improve the ability to distinguish closely related species, the other is to construct local DNA barcoding library in order to expand applications of DNA barcoding. For the forestry, DNA barcoding has gained adoption in a set of diverse applied contexts, including wood identification, community ecology and biodiversity monitoring, but there still are several challenges, for example, woody sample degradation and the amplification of the whole barcode. And proceeding barcoding studies in forestry needs to concern on the choice of barcodes, the construction of barcoding library for woody species, the method of data analysis and the combination with next generation sequencing. In the future, DNA barcoding will play a key role in the evaluation, protection and sustainable development of forestry resources.
