Mentha (Lamiaceae) Phylogenetic Analysis Using Chloroplast TRNL-TRNF and Nuclear Ribosomal DNA ITS Sequences
… using DNA sequence data from the chloroplast trnL-trnF and nuclear ribosomal internal transcribed spacer (ITS) regions. Based on trnL-trnF data, Mentha appears monophyletic. However, ITS data place the Mentha species into two distinct clades that include 12 other Mentheae genera. None of the …

Phylogenetic relationships of the Genus Andreaea Hedw.(Andreaeceae,Bryophyta) as inferred from RPS4 and TRNL-F sequences and morphology
… generated from two chloroplast gene loci, the trnL-F intergenic spacer and the coding region of the ribosomal protein S4 (rps4). Separate morphological and molecular analyses produced topologies incongruent in certain parts and congruent in others. However, their combined analysis was better …

Reassessment of Species Boundaries and Phylogenetic Relationships in the Desmodium ciliare complex (Fabaceae) Using Morphological and DNA Data
… characteristics and analyses of both plastid <em>trnL</em>–<em>trnL</em>-<em>F</em> and nuclear ITS DNA were utilized. Based on phylogenetic analysis using 73 ITS and 12 <em>trnL</em>–<em>trnL</em>-<em>F</em> sequences, there was not enough resolution to circumscribe the <em>Desmodium </em>species …

Is Alnus viridis 'a' glacial relict in the Black Forest ?
… sequences of the noncoding trnT-trnF (trnT-L and trnL-F-spacers and trnL-intron) region of the chloroplast genome. Based on the base-pair variations, in the trnL-trnF region all individual population of A. viridis were cluster into 9 groups. However, within the Black Forest at least six different …

Nymphaea odorata (Water-lily, Nymphaeaceae): Analyses of molecular and morphological studies
… transcribed spacer (ITS) region, the chloroplast trnL-F region, and inter-simple sequence repeat (ISSR) markers determined the variation present between and within two species of Nymphaea. The ITS region resulted in a phylogeny depicting strong separation between species (N. mexicana and N. …

Mollecular Phylogeny of tribolium (Danthoniodeae: Poaceae) and its taxonomic implications
… data from two noncoding regions of D A (ITS AND TRNL-F) Were used to produce a phylogeny for the genus Tribolium and its African and Australasian allies. Topological comparisons of the combined molecular data with the appended existing morphological tree were made. A significant incongruence was …

Systematic studies on Thysanotus R.Br. (Asparagales: Laxmanniaceae).
… signal of these characters. The cp DNA (trnL intron and trnL–F intergenic spacer) and nuclear ITS2 gene regions were amplified and the results compared and combined with a morphological analysis. Phylogenetic analyses were carried out using Arthropodium R.Br and Eustrephus R.Br as …

Molecular systematics of the cashew family (Anacardiaceae)
… DNA sequence data for the chloroplast trnL intron and 3’ exon, and the intergenic spacer between trnL and trnF (trnLF) of Anacardiaceae, Burseraceae, Julianiaceae, Pistaciaceae, Podoaceae, Rutaceae, and Sapindaceae were generated to reconstruct phylogenetic relationships of these …

Phylogeny reconstruction of the Schoeneae (Cyperaceae) with a focus on southern African genera
… both plastid and nuclear DNA sequences (rbcL, trnL-trnF, rps16, ITS and ETS) were analysed. New sequences were added to the matrix from Verboom (2006). Parsimony method was used for phylogeny reconstruction. Morphological characters were then optimised on the parsimony tree using both maximum …

Testing the utility of the consortium for the barcoding of life's two 'agreed upon' plant DNA barcodes, matK and rbcL
… of three noncoding cpDNA regions (trnH-psbA, trnL-trnL-trnF, and trnS-trnG-trnG) at identifying species from the genus Prunus L. Upon the announcement by CBOL, additional sequence data was generated for matK and rbcL using the same Prunus taxa to determine how well these two regions would …
