Rhei Rhizoma (Dahuang in Chinese) is widely known as a purgative and antiinflammatory agent. In the Japanese Pharmacopoeia, Rhei Rhizoma is prescribed for four Rheum species, Rheum palmatum, R. tanguticum, R. officinale, and R. coreanum, while the first three species are prescribed for Dahuang in the Chinese Pharmacopoeia. Due to the morphologic similarity of the aerial parts and frequent occur...
The Atlantic Forest is a phytogeographic domain with a high rate of endemism and large species diversity. The Sapotaceae is a botanical family for which species identification in the Atlantic Forest is difficult. An approach that facilitates species identification in the Sapotaceae is urgently needed because this family includes threatened species and valuable timber species. In this context, D...
DNA barcoding is expected to be one of the most promising tools in biological taxonomy. However, there have been no agreements on which core barcode should be used in plants, especially in species-rich genera with wide geographical distributions. To evaluate their discriminatory power in large genera, four of the most widely used DNA barcodes, including three plastid regions (matK, rbcL, trnH-p...
بارکدگذاری DNA روشی ساده برای شناسایی گونهها با استفاده از یک توالی کوتاه ژنتیکی از یک بخش استاندارد ژنوم است. این روش به منظور شناسایی هشت گیاه دارویی جمعآوریشده از استان اردبیل مورد استفاده واقع شد. استخراج DNA به روش تغییریافته CTAB انجام گرفت و PCR با آغازگرهای طراحیشده بر اساس بارکدهای کلروپلاستی rbcL، trnH-psbA، matK و بارکد هستهای ITS انجام شد. سپس محصولات PCR خالصسازی و تعیین ت...

DNA barcoding of perennial fruit tree species of agronomic interest in the genus Annona (Annonaceae)
The DNA barcode initiative aims to establish a universal protocol using short genetic sequences to discriminate among animal and plant species. Although many markers have been proposed to become the barcode of plants, the Consortium for the Barcode of Life (CBOL) Plant Working Group recommended using as a core the combination of two portions of plastid coding region, rbcL and matK. In this pape...
The orchid genus Oberonia Lindl., is a taxonomically complex genus characterized by recent species radiations and many closely related species. All Oberonia species are under conservation as listed in the CITES and the IUCN Red List Categories and Criteria. Given its difficulties in taxonomy and conservation status, Oberonia is an excellent model for developing DNA barcodes. Three analytical me...
DNA barcoding is a fast-developing technique to identify species by using short and standard DNA sequences. Universal selection of DNA barcodes in ferns remains unresolved. In this study, five plastid regions (rbcL, matK, trnH-psbA, trnL-F and rps4-trnS) and eight nuclear regions (ITS, pgiC, gapC, LEAFY, ITS2, IBR3_2, DET1, and SQD1_1) were screened and evaluated in the fern genus Adiantum from...
To elucidate the affinity and phylogeny of the endemic North American genus Uvularia, two chloroplast genes, matK and rbcL, were sequenced for all five species of the genus {Uvularia floridana, U. grandifolia, U. perfoliata, U. puberula, and U. sessilifolia) and four selected members of the Liliales (Erythronium japonicum, Disporum sessile, Medeola virginiana, and Clintonia borealis). Sequence ...
