The genus Onosma is a homogeneous taxon with high morphological variation and due to the similarities among taxa, there are many problems in their identification. Hence, systematically taxonomically, it considered difficult genus. In present study, we included large number of species throughout distribution range. Using nuclear (ITS) two plastids (rpl32-trnL(UAG) trnH-psbA) markers, analyzed ev...

This study proposes the use of genetic analysis as a complementary method for species identification in genus Pinus, particularly cases where anatomical is challenging. Pinus were grouped based on similarities, and efficacy using ycf1b, which most variable identification, rbcL, suggested DNA barcode land plants, was evaluated within each group. Sequences obtained from National Center Biotechnol...

Abstract— The Lathberry Clade includes seven species of Eugenia sect. Umbellatae (Myrtaceae) distributed from Puerto Rico through the Lesser Antilles. Members are trees and shrubs distinguished other Antillean by a combination dull twigs, glabrous leaves with raised midvein, glomerate or fasciculate inflorescences predominantly borne below on old wood, closely spaced ascending inflorescence bra...

In this study, 3 haplotypes were found in populations of Phellodendron amurense based on two combined cpDNA regions (psbA-trnH and trnT-trnL). Nucleotide diversity haplotype 0.43×10 -3 0.41, respectively at the level species. The AMOVA revealed that only 8.53% variation was explained by differences among geographical groups, whereas inter-population intrapopulation 18.32% 71.35% variation, resp...

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...
