Phylogenetics of Taxus Using the Internal Transcribed Spacers of Nuclear Ribosomal DNA and Plastid trnL-F Regions

Phylogenetics of Papaver and related genera based on DNA sequences from ITS nuclear ribosomal DNA and plastid trnL intron and trnL-F intergenic spacers.

BACKGROUND AND AIMS Representatives from Papaver, Roemeria, Stylomecon and Meconopsis were studied to elucidate phylogenetic relationships between Papaver and these closely allied genera. METHODS Two molecular data sets were used individually and combined and included sequences from the internally transcribed spacer region (ITS) of 18S-26S nuclear ribosomal DNA and the trnL intron and the trn...

The Phylogeny of Calligonum and Pteropyrum (Polygonaceae) Based on Nuclear Ribosomal DNA ITS and Chloroplast trnL-F Sequences

This study represents phylogenetic analyses of two woody polygonaceous genera Calligonum and Pteropyrum using both chloroplast fragment (trnL-F) and the nuclear ribosomal internal transcribed spacer (nrDNA ITS) sequence data. All inferred phylogenies using parsimony and Bayesian methods showed that Calligonum and Pteropyrum are both monophyletic and closely related taxa. They have no affinity w...

Rapid detection, discrimination and quantification of Theileria orientalis types using ribosomal DNA internal transcribed spacers

Phylogeny of Chloranthus (Chloranthaceae) based on nuclear ribosomal ITS and plastid TRNL-F sequence data.

The internal transcribed spacers (ITS) of the nuclear ribosomal DNA and trnL-F region of the chloroplast DNA were sequenced for all ten species of Chloranthus and the outgroup Sarcandra (Chloranthaceae). Parsimony analyses of separate and combined data sets strongly suggest that Chloranthus is monophyletic and can be divided into two major clades: one containing C. erectus, C. spicatus, C. serr...
