Species identification of medicinal pteridophytes by a DNA barcode marker, the chloroplast psbA-trnH intergenic region.
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...
متن کاملUtility of the trnH–psbA Intergenic Spacer Region and Its Combinations as Plant DNA Barcodes: A Meta-Analysis
BACKGROUND The trnH-psbA intergenic spacer region has been used in many DNA barcoding studies. However, a comprehensive evaluation with rigorous sequence preprocessing and statistical testing on the utility of trnH-psbA and its combinations as DNA barcodes is lacking. METHODOLOGY/PRINCIPAL FINDINGS Sequences were searched from GenBank for a meta-analysis on the usefulness of trnH-psbA and its...
متن کاملPhylogenetic Analysis of Some Luffa Genotypes Based on the sequence of intergenic region of trnH-psbA
Luffa (Luffa cylindrica) is a plant from the Cucurbitaceae family that grows mostly in tropical and subtropical regions, as well as in most regions of Iran. In this research, the genetic diversity of nine native and non-native genotypes of L. cylindrica was investigated through the evaluation of the chloroplast trnH-psbA intergenic region (IGS). After sampling the young leaves, DNA extraction w...
متن کاملAssessment of relationships between Iranian Fritillaria (Liliaceae) Species Using Chloroplast trnh-psba Sequences and Morphological Characters
The genus Fritillaria comprises of 165 taxa of medicinal, ornamental and horticultural importance. Evolutionary relationships in this genus is an interesting research area, attracting many researchers. In this study, phylogenetic relationships among 18 native to endemic species in Iran belonging to four subgenera Petilium, Theresia, Rhinopetalum and Fritillaria, are assessed using chloroplast t...
متن کاملSpecies identification and strain differentiation of dermatophyte fungi by analysis of ribosomal-DNA intergenic spacer regions.
Restriction fragment length polymorphisms (RFLPs) identified in the ribosomal-DNA (rDNA) repeat were used for molecular strain differentiation of the dermatophyte fungus Trichophyton rubrum. The polymorphisms were detected by hybridization of EcoRI-digested T. rubrum genomic DNAs with a probe amplified from the small-subunit (18S) rDNA and adjacent internal transcribed spacer (ITS) regions. The...
