Piper species are used for spices, in traditional and processed forms of medicines, in cosmetic compounds, in cultural activities and insecticides. Here barcode analysis was performed for identification of plant parts, young plants and modified forms of plants. Thirty-six Piper species were collected and the three barcode regions, matK, rbcL and psbA-trnH spacer, were amplified, sequenced and a...

In a striking contrast, matK is one of the most rapidly evolving plastid genes and also one of the few plastid genes to be retained in all nonphotosynthetic plants examined to date. DNA sequences of this region were obtained from photosynthetic and nonphotosynthetic plants of Orobanchaceae and their relatives. The resulting plastid DNA phylogeny was congruent with that recently obtained from an...

Andaliman (Zanthoxylum acanthopodium DC) is a native plant of North Sumatra province. Zanthoxylum member Rutaceae family widely found in northern Sumatra, Indonesia. The aim this study was to barcode Z. province, Indonesia based on cpDNA maturase K (matK). Samples were collected seven localities across six regions Phylogenetic analysis conducted using Maximum Likelihood method. results phylogen...

Two new species, Machilus bokorensis Yahara & Tagane and Machilus brevipaniculata Yahara & Tagane (Lauraceae) are described from Bokor National Park, Cambodia with their illustrations and DNA barcodes of the two plastid regions of rbcL and matK and the nuclear region of ITS.

Many species of Schisandraceae are used in traditional Chinese medicine and are faced with contamination and substitution risks due to inaccurate identification. Here, we investigated the discriminatory power of four commonly used DNA barcoding loci (ITS, trnH-psbA, matK, and rbcL) and corresponding multi-locus combinations for 135 individuals from 33 species of Schisandraceae, using distance-,...

Dryobalanops belong to a member of Dipterocarpaceae, which has high economic value. Due illegal harvesting for its wood, the population tends decrease every year, so rapid conservation effort was needed. D. oblongifolia and lanceolata were important members dryobalanops, have listed as endangered (EN), according IUCN. This study aims provide information on DNA isolation amplification process. d...
