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 …

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 …

Molecular phylogeny of Tribolium (Danthonioideae: Poaceae) and its taxonomic implications
… data from two noncoding regions of DNA (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 …

Cyperaceae tribe Cyperae : phylogenetic relationships and evolutionary patterns of diagnostic characters
… matrix, which consisted of plastid DNA (rbcL, trnL-F intergenic spacer, and rps16), nuclear ribosomal DNA (internal transcribed spacer ITS) sequences and morphological data. From both analyses, tribe Cypereae were resolved into a very strongly supported clade (Posterior probability =98%; …

Phylogenetic Study of Apocynaceae Juss. And Aspidosperma Mart. And Zucc
… (ITS-1 and ITS-2) and the chloroplast genome (trnL intron and trnL-F spacer). Phylogenies derived independently for each molecular data set were compared to assess possible hybridization. Parsimony analysis of all the data combined did not support the subgeneric concept proposed by some …

Molecular Phylogeny of the Genus Houstonia and Allies in Rubiaceae
… two sections. Nuclear (ITS) and plastid (trnL-F, rps16) DNA sequences were used to build a molecular phylogeny depicting relationships within Houstonia and among the closely related genera Stenaria and Stenotis, all of which used to be considered Hedyotis. Separate and combined datasets …

Phylogenetic and functional growth from diversification in the Cape grass genus Ehrharta Thunb
… data from two noncoding regions of DNA (lTS1 and trnL-F) are used to produce a phylogenetic hypothesis for the tribe Ehrharteae. Combined analysis of these data sets resolves four principal clades that approximate the genera Ehrharta s. s., Micro/aena, Tetrarrhena and Zotovia and this result thus …

Further studies with Melianthus L. : a molecular phylogeny, evolutionary patterns of diversification in the genus and pollinator syndromes
… Melianthus L. based on two plastid markers (trnL-F and psbA-trnH) and one nuclear marker (ITS). Topological comparisons with a tree based on an existing morphological data set revealed significant incongruence leading to a loss of resolution upon combination. Ultimately, the combined …

Phylogenetics of North American Psoraleeae (Leguminosae): Rates and Dates in a Recent, Rapid Radiation
… Psoraleeae based on six chloroplast (trnD/T, trnL/F, trnS/G, trnK, matK, and rpoB-trnC) and two nuclear (ITS and waxy) DNA regions. This study explores approaches for coding insertion-deletion events (gaps) as phylogenetic characters using maximum parsimony and Bayesian Inference. Inclusion of …

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 …

Palaeoclimatic impacts on the phylogeography of an Afro-montane liverwort: Jamesoniella colorata (Lophoziaceae )
… chloroplast mutation rate was applied to the trnL-F cpDNA mismatch distribution. The results roughly place the expansions within the last glacial period, demonstrating the general accordance of the phylogeographical and palaeoclimatic data. The molecular work in this study also brought into …

Molecular Phylogenetics and Historical Biogeography of the Tribe Chiococceae (Rubiaceae)
… (ETS, ITS) and two chloroplast (<em>petD, trnL-F</em>) regions using Bayesian inference and maximum parsimony frameworks, a total of nine new taxonomic changes are proposed- generic recognition for five new genera, and synonymization and new combinations for three genera (<em> …

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 …

Systematic studies of the South African Campanulaceae sensu stricto with and emphasis on generic delimitations
… and DNA sequence data from the chloroplast trnL-F and the nuclear ITS regions. These data sets were analyzed separately and in combination. The phylogenetic hypothesis was used to re-assess the questionable generic boundaries in the family. The ITS data produced poor resolution under …

Phylogenetics of the Malacothamnus alliance (Malvaceae): Assessing the role of hybridization and molecular and morphological variation in species delineation
The Malacothamnus alliance consists of three genera, Iliamna, Malacothamnus, and Phymosia. The genera are considered taxonomically complex since hybridization freely occurs, polyploidy levels vary, and there is a lack of distinct morphological characters to delineate taxa. Several taxonomic …
