[DNA bacording of Verbenaceae medicinal plant by using ITS2 and psbA-trnH region].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2012
To evaluate the ability of several hotspot candidate sequence of DNA barcodes for identifying medicinal plant species in Verbenaceae.Using universal primers, three chloroplast sequences, psbA-trnH, rbcL, matK, two nuclear ribosomal DNA ITS2 and ITS were amplified and sequenced.

Cytogenetic and ITS-psbA-trnH Sequence Analysis for Phylogenetic Inference in Mucuna sp. of India

Tropical Plant Biology, 2015
This paper reports new chromosomal information and earliest proof on efficacy of nrITS and cp-psbA-trnH gene sequences for barcoding and phylogenetic studies in Mucuna sp. First cytological evidence on M. sempervirens and M. bracteata revealed symmetrical karyotype in both the species.

Phylogenetic relationships among Artemisia species based on nuclear ITS and chloroplast psbA-trnH DNA markers

Biologia (Poland), 2014
The taxonomic and phylogenetic relationships within the genus Artemisia s.l. (Asteraceae) are controversial, and it has been considered 1 to 8 different genera. This work re-investigated the phylogenetic relationships in Artemisia using nuclear ribosomal (ITS) and chloroplast psbA-trnH DNA sequences using three sections of Artemisia, Dracunculus, and ...

Identification and characterization of the Arabidopsis thaliana chloroplast DNA region containing the genes psbA, trnH and rps19′

Current Genetics, 1995
A 1887-nucleotide chloroplast-DNA region from Arabidopsis thaliana was analyzed. It contains the conserved genes psbA for the precursor of the D1 reaction-centre protein of photosystem II, trnH for tRNAHis, and rps19' for the 6.8-kDa protein of the small ribosomal subunit. Northern hybridization and RNase protection experiments suggest co-transcription

Notice of Retraction: A Molecular Phylogenetic Analysis of the Genus Rhododendron Based on psbA-trnH Sequences

2011 5th International Conference on Bioinformatics and Biomedical Engineering, 2011
Phylogenetic relationships within the genus Rhododendron were studied using psbA-trnH intergenic spacer sequences. In the analysis, forty samples of thirty-six Rhododendron species, which belong to seven subgenus according to taxonomy system of Sleumer in "Flora of China" were analyzed.

[Analysis and authentication of cpDNA psbA-trnH regions of Dendrobium species of fengdous].

Yao xue xue bao = Acta pharmaceutica Sinica, 2012
The psbA-trnH regions of Dendrobium species of Fengdous were sequenced by our research group. The psbA-trnH sequences of fifteen Dendrobium species were analyzed with software MEGA 4.0. The results showed that the lengths of sequences varied from 721 to 767 bp. The variable sites were 42 while the informative sites were 11.

[Identification of Dioscorea nipponica and its sects based on psbA-trnH barcode].

Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2019
A rapid and accurate method was established by psbA-trnH sequence to distinguish Dioscorea nipponica from other species belonging to the same genus.In this study, we collected 144 samples of D. nipponica from 17 different producing areas in China, the psbA-trnH sequenced of 23 nucleotide sequences were downloaded from GenBank, the sequences from ...

Identification ofDendrobiumSpecies by a Candidate DNA Barcode Sequence: The ChloroplastpsbA-trnHIntergenic Region

Planta Medica, 2009
DNA barcoding is a novel technology that uses a standard DNA sequence to facilitate species identification. Although a consensus has not been reached regarding which DNA sequences can be used as the best plant barcodes, the psbA-trnH spacer region has been tested extensively in recent years.

Generic relationships and dating of lineages in Winteraceae based on nuclear (ITS) and plastid (rpS16 and psbA-trnH) sequence data

Molecular Phylogenetics and Evolution, 2009
Phylogenetic analyses of representative species from the five genera of Winteraceae (Drimys, Pseudowintera, Takhtajania, Tasmannia, and Zygogynum s.l.) were performed using ITS nuclear sequences and a combined data-set of ITS+psbA-trnH+rpS16 sequences (sampling of 30 and 15 species, respectively).

Molecular phylogenetic identification of Cyrtomium adenotrichum based on rbcL and psbA-trnH barcoding

Mitteilungen Klosterneuburg
Traditionally, new plant species identification relied primarily on morphological characteristics. However, molecular methods have now been demonstrated to provide more reliable identification. Cyrtomium adenotrichum, a fern species discovered in the Nandan limestone area of Guangxi, China, was initially described as a new species based on its distinct
