Phylogenetics of Papaver and Related Genera Based on DNA Sequences from ITS Nuclear Ribosomal DNA and Plastid trnL Intron and trnL–F Intergenic Spacers [PDF]

Annals of Botany, 2006
Representatives from Papaver, Roemeria, Stylomecon and Meconopsis were studied to elucidate phylogenetic relationships between Papaver and these closely allied genera.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

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

A molecular phylogenetic study of Deschampsia (Poaceae: Aveneae) inferred from nuclear ITS and plastid trnL sequence data: support for the recognition of Avenella and Vahlodea [PDF]

, 2007
The circumscription and phylogeny of Deschampsia were studied for the first time by parsimony analysis of nuclear ribosomal internal transcribed spacer (ITS) and plastid trnL intron sequences.

Sequence Analysis of the Internal Transcribed Spacer (ITS) Region of the Nuclear Ribosomal DNA (nrDNA) and Chloroplast trnL-F Region (cpDNA) of Some <i>Lactuca</i> L. (Asteraceae) Species in Turkey

Notulae Scientia Biologicae, 2016
In the current study, sequence analysis of some Turkish Lactuca L. species using nrITS DNA and trnL-F cpDNA sequences were performed to elucidate phylogenetic relationships among the taxa under study.

Repeat-type distribution in trnL intron does not correspond with species phylogeny: comparison of the genetic markers 16S rRNA and trnL intron in heterocystous cyanobacteria [PDF]

International Journal of Systematic and Evolutionary Microbiology, 2004
tRNALeu UAA (trnL) intron sequences are used as genetic markers for differentiating cyanobacteria and for constructing phylogenies, since the introns are thought to be more variable among close relatives than is the 16S rRNA gene, the conventional phylogenetic marker.

Complete chloroplast genome of Triticum aestivum cultivar ‘Keumkang’ from Korea (Poaceae) and comparative chloroplast genomes of the members of the Triticum genus

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Bread wheat (Triticum aestivum L.) is a major global food crop, and understanding its maternal lineage and genetic diversity is essential for breeding, authentication, and evolutionary studies. Chloroplast genomes provide valuable markers for phylogenetic inference and cultivar discrimination; however, conventional plant DNA ...

A chloroplast phylogeny of Arisaema (Araceae) illustrates Tertiary floristic links between Asia, North America, and East Africa [PDF]

, 2004
The evolution of Arisaema is reconstructed, based on combined sequences (2048 aligned bases) from the chloroplast trnL intron, trnL-trnF spacer, and rpl20-rps12 spacer obtained for species from all 11 sections, including sectional type species and ...
