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...

Leucobryum boninense is endemic to the Bonin Islands, Japan, and its related species are widely distributed in Asia and the Pacific. We aimed to clarify the phylogenetic relationships among Leucobryum species and infer the origin of L. boninense. We also describe the utility of the chloroplast trnK intron including matK for resolving the phylogenetic relationships among Leucobryum species, as p...

1 This paper has also appeared in the proceedings of the LSK International Conference held in Seoul, Korea, in August 2002, and has been revised. I thank the audience at the LSK conference for their feedback on the earlier version. 2 I would like to thank Arto Anttila, Vivienne Fong, K.P. Mohanan, and my supervisor Tara Mohanan for their valuable comments and suggestions on an earlier version o...

MaturaseK gene (matK) of chloroplast is highly conserved in plant systematics which is involved in Group-II intron splicing. The size of the gene is approximately 1500 base pairs in length, located with in the intron of trnK. In the present study, matK gene from Cucurbitaceae was taken for the analysis of variants, parsimony site, patterns, transition/ transversion rate and phylogeny. The famil...

BACKGROUND Dioscorea is an important plant genus in terms of food supply and pharmaceutical applications. However, its classification and identification are controversial. DNA barcoding is a recent aid to taxonomic identification and uses a short standardized DNA region to discriminate plant species. In this study, the applicability of three candidate DNA barcodes (rbcL, matK, and psbA-trnH) to...

Melilotus is an important genus of legume plants and an herbage with excellent nitrogen fixation; it can tolerate extreme environmental conditions and possesses important medicinal value. However, there is limited genetic information about the genus; thus, we analysed four chloroplast loci (rbcL, matK, psbA-trnH and trnL-F) and one nuclear region (ITS) to determine the genetic diversity of 199 ...

DNA barcoding is a tool for species identification. For plant species identification, two of plastid genes (rbcL and matK) were used as standard barcodes. There are limitations of each gene marker but matK is considered to be the closest plant analogue to the CO1 animal barcode. As a mega-biodiversity country, Indonesia has many plant species used for ornamental and/or medical purposes. This st...

Anacardiaceae is well-known for its edible fruits and economically important species in Indonesia. Approximately 3% of Indonesia's endangered vulnerable belong to this family. Fast accurate identification crucial support the conservation efforts family, such as employing DNA sequences. Species using sequences, known barcoding, has been widely used many applied fields. So far, application barcod...

A DNA barcode is a DNA fragment used to identify species. For land plants, DNA fragments of plastid genome could be the primary consideration. Unfortunately, most of the plastid candidate barcodes lack species-level resolution. The identification of DNA barcodes of high resolution at species level is critical to the success of DNA barcoding in plants. We searched the available plastid genomes f...

DNA barcoding is a desirable tool for medicinal product authentication. DNA barcoding is a method for species identification using short DNA sequences that are conserved within species, but variable between species. Unlike animals, there is no single universal DNA barcode locus for plants. Coding markers, matK and rbcL, and noncoding markers, trnH-psbA (chloroplast) and ITS2 (nuclear), have bee...
