Incorporating trnH-psbA to the core DNA barcodes improves significantly species discrimination within southern African Combretaceae
Recent studies indicate that the discriminatory power of the core DNA barcodes (rbcLa + matK) for land plants may have been overestimated since their performance have been tested only on few closely related species. In this study we focused mainly on how the addition of complementary barcodes (nrITS and trnH-psbA) to the core barcodes will affect the performance of the core barcodes in discrimi...
متن کاملITS and trnH-psbA as Efficient DNA Barcodes to Identify Threatened Commercial Woody Angiosperms from Southern Brazilian Atlantic Rainforests
The Araucaria Forests in southern Brazil are part of the Atlantic Rainforest, a key hotspot for global biodiversity. This habitat has experienced extensive losses of vegetation cover due to commercial logging and the intense use of wood resources for construction and furniture manufacturing. The absence of precise taxonomic tools for identifying Araucaria Forest tree species motivated us to tes...
متن کاملUtility of the trnH–psbA Intergenic Spacer Region and Its Combinations as Plant DNA Barcodes: A Meta-Analysis
BACKGROUND The trnH-psbA intergenic spacer region has been used in many DNA barcoding studies. However, a comprehensive evaluation with rigorous sequence preprocessing and statistical testing on the utility of trnH-psbA and its combinations as DNA barcodes is lacking. METHODOLOGY/PRINCIPAL FINDINGS Sequences were searched from GenBank for a meta-analysis on the usefulness of trnH-psbA and its...
متن کاملSpecies identification of medicinal pteridophytes by a DNA barcode marker, the chloroplast psbA-trnH intergenic region.
Medicinal pteridophytes are an important group used in traditional Chinese medicine; however, there is no simple and universal way to differentiate various species of this group by morphological traits. A novel technology termed "DNA barcoding" could discriminate species by a standard DNA sequence with universal primers and sufficient variation. To determine whether DNA barcoding would be effec...
متن کاملInternal Transcribed Spacer (its), an Ideal Dna Barcode for Species Discrimination in Crawfurdia Wall. (gentianaceae)
BACKGROUND DNA barcoding is a technique used to identify species based on species-specific differences in short regions of their DNA. It is widely used in species discrimination of medicinal plants and traditional medicines. MATERIALS AND METHODS In the present study, four potential DNA barcodes, namely rbcL, matK, trnH-psbA and ITS (nuclear ribosomal internal transcribed spacer) were adopted...
