[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, 2012To 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.

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 ...

Four out of twenty-two species of the genus Goniolimon are common in Ukraine: G. besserianum, G. graminifoli-um, G. rubellum and G. tataricum. Two of them, G. graminifolium and G. rubellum, are listed as vulnerable species in the Red Data Book of Ukraine. Some populations of both species are sometimes reported under different species names, manly as G.

Cytogenetic and ITS-psbA-trnH Sequence Analysis for Phylogenetic Inference in Mucuna sp. of India
Tropical Plant Biology, 2015This 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.

[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, 2019A 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 ...

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

Zelkova, a relic of the Cenozoic, is an element of Northern Hemisphere woodlands. We sequenced and combined ITS and trnL-trnF, psbA-trnH, and rbcL to reconstruct a phylogenetic tree. The result shows that there are two geographical groups, East Asia and western Asia–southern Europe appeared within Zelkova. The age of Zelkova was traced to Cretaceous ca.

Barkodlama Bölgesi Olarak Potentilla L. Cinsinde psbA-trnH IGS Sekanslarının Değerlendirmesi
2023Potentilla cinsi 400’den fazla türle, morfolojik değişimlere neden olan geniş bir yayılışa sahiptir. Geniş yayılışın yanı sıra, cinsteki hibridizasyon, introgression, otopoliploidi ve allopoliploidi gibi birçok durum gözlemlenir. Bunlar, yanlış tanımlamalara ve taksonomik problemlere yol açabilir. DNA barkodlama çalışmaları, tür tanımlama ve taksonomik

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.

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
