Phylogeography of Chrysanthemum indicum L. (Compositae) in China based on trnL-F sequences
Biochemical Systematics and Ecology, 2010Abstract Using chloroplast DNA (cpDNA) trnL-F sequences, we studied the phylogeographic pattern and demographic history of Chrysanthemum indicum with 81 individuals from 27 populations representing the partial geographic range in China. Fifteen haplotypes were identified based on nucleotide variation. Relatively high levels of haplotype diversity (Hd

Phylogenetic analysis of IRIS L. from China on chloroplast TRNL-F sequences
Biologia, 2018Phylogenetic relationships among the six Iris subgenera were reconstructed by chloroplast trnL-F sequences data using maximum likelihood. The entire matrix of aligned bases analyzed includes 1043 characters and the length of all sequences varied from 747 bp to 893 bp, and mutation sites accounted for 18.79% of the total length.

Ophioglossaceae are a putatively ancient lineage of ferns in which the aerial portion of the plant is composed of a single leaf. The simplicity of foliar morphology has limited the number of characters available for constructing classifications and contributed to taxonomic difficulties at nearly every level of classification within the family. Analysis

Both nuclear ribosomal ITS and chloroplast trnL-F sequences were acquired for 57 species (accessions) of Lysimachia and its close relatives, and were analyzed together with sequences retrieved from databases. The results of phylogenetic analyses based on these data (separately or combined) show that Lysimachia is paraphyletic, with the monotypic genus ...

The chloroplast trnL-F region was used as an independent data set for phylogenetic analysis of 118 aroid taxa. We investigated the intergeneric relationships of subfamily Monsteroideae (Araceae) and used this as a basis for an interspecific phylogenetic study of Rhaphidophora Hassk., the largest genus of the Monsteroideae. Results of the molecular tree

ITS and trnL-F Sequences Analysis of Potentilla bifurca L var. humilior Rupr.
2015 Seventh International Conference on Measuring Technology and Mechatronics Automation, 2015To provide scientific data of the internal transcribed spacer (ITS) and chloroplast trn L-F sequences for identification of Potentilla bifurca L var. Humilior Rupr., we extracted the genome DNA from the leaves of Potentilla bifurca L var. Humilior Rupr.

Phylogeny of korean rubus (rosaceae) based on its (nrDNA) and trnL/F intergenic region (cpdna)
Journal of Plant Biology, 2006We examined the phylogeny of the genusRubus in Korea using an internal transcribed spacer (ITS) of the nuclear ribosomal DNA and a trnL-trnF (trnL/F) intergenic region of the chloroplast DNA. In all, 21 ingroup species (1.2 kb for each species) were analyzed using parsimony, resulting in 672 aligned sequences from ITS, and 502 bases with trnL/F ...

Polystichum is one of the largest and most taxonomically complex fern genera in China. The evolutionary relationships of Chinese Polystichum and related genera, and the relationship between our Polystichum phylogeny and ecogeographic distribution, were tested by the use of DNA sequence data.

Abstract The genera of tribe Sipaneeae have been either included within tribe Rondeletieae or treated as its sister tribe, and historically placed in subfamily Cinchonoideae. The herbaceous habit was the only character used to separate Sipaneeae from Rondeletieae. Recent molecular phylogenies included

Molecular phylogeny of Incarvillea (Bignoniaceae) based on ITS and trnL-F sequences.
American journal of botany, 2012Incarvillea is a herbaceous and temperate member of Bignoniaceae, previously divided into four subgenera, Niedzwedzkia, Amphicome, Incarvillea, and Pteroscleris. Niedzwedzkia and Amphicome have in the past been treated as independent genera. Different relationships have been proposed for the four subgenera.
