Dryopteris blanfordii (C.Hope) C.Chr. is a member of the Dryopteridaceae, growing in high altitude Picea or Abies forests (2900-3500 m) in China and India. Phylogenetic relationships between D. blanfordii subsp. nigrosquamosa and closely related species of Dryopteris were investigated using a combined analysis of multiple molecular data sets (the protein-coding region of rbcL and matK genes and...

DNA barcoding involves sequencing a standard region of DNA as a tool for species identification. However, there has been no agreement on which region(s) should be used for barcoding land plants. To provide a community recommendation on a standard plant barcode, we have compared the performance of 7 leading candidate plastid DNA regions (atpF-atpH spacer, matK gene, rbcL gene, rpoB gene, rpoC1 g...

DNA barcoding, as a tool for species discrimination, has been efficiently used in animals. However, there are still debates on which DNA region (s) can be adopted as the standard barcode (s) for land plants. In the present study, we evaluated the four proposed barcoding loci (matK, rbcL, trnH-psbA and ITS) on nine species of Nyssaceae. The results showed that ITS was the best performing single ...

Data is presented in support of a phylogenetic reconstruction of the species-rich early-divergent angiosperm genus Goniothalamus (Annonaceae) (Tang et al., Mol. Phylogenetic Evol., 2015) [1], inferred using chloroplast DNA (cpDNA) sequences. The data includes a list of primers for amplification and sequencing for nine cpDNA regions: atpB-rbcL, matK, ndhF, psbA-trnH, psbM-trnD, rbcL, trnL-F, trn...

Genus Paphiopedilum has species having lovely flowers which are incredibly attractive to everyone. Their ornamental and commercial value caused over-collection illegal poaching trade. Due these reasons, nowadays, the Venus slipper orchids facing deplete in nature. Therefore, it is important consider conservation. Mainly, necessary prioritize identification phylogenetic analysis methods of genus...

Paphiopedilum là một chi nổi bật của nhóm lan Hài, đây nhỏ nhưng có hệ thống phân loại phức tạp với nhiều quan điểm khác nhau. canhii phát hiện năm 2010 và được coi loài đặc hữu Việt Nam. Các nghiên cứu về cho thấy vị trí rất riêng biệt chúng. Để chính xác này, người ta đã phải sử dụng tiêu chí kết hợp. Hiện nay, ngoài phương pháp truyền bằng hình thái, thì chỉ thị tử triển thể ưu khi các học. ...

Medicinal pteridophytes are an important group used in traditional Chinese medicine; however, there is no simple and universal way to differentiate various species of this group by morphological traits. A novel technology termed "DNA barcoding" could discriminate species by a standard DNA sequence with universal primers and sufficient variation. To determine whether DNA barcoding would be effec...

Accurate identification of Arctic plant species is critical for understanding potential climate-induced changes in their diversity and distributions. To facilitate rapid identification we generated DNA barcodes for the core plastid barcode loci (rbcL and matK) for 490 vascular plant species, representing nearly half of the Canadian Arctic flora and 93% of the flora of the Canadian Arctic Archip...

Camellia is a large genus in the tea family of Theaceae. In this genus, several species serve different purposes, such as, medicinal and ornamental plants beverage production. Thus, country-wide cultivation various sought to alleviate poverty promote economic development many regions. However, studies on evaluating its genetic resources as foundation for conservation plant are yet start. Curren...

Hopea chinensis (synonym: H. hongayensis) (Dipterocarpaceae) is a threatened species found so far in only two locations: Quang Ninh (Vietnam) and Guangxi (China). The species shares many morphological characteristics with H. mollissima and the two species are often confused. To overcome this problem of identification and to investigate the genetic relationships of Hopea species with other Dipte...
