Screening of universal DNA barcodes for identifying grass species of Gramineae

Frontiers in Plant Science, 2022
There is currently international interest in applying DNA barcoding as a tool for plant species discrimination and identification. In this study, we evaluated the utility of four candidate plant DNA barcoding regions [rbcL, matK, trnL-F, and internal ...

A New Species of Arthropteris From Samoa

New Zealand Journal of Botany, Volume 64, Issue 2, June 2026.
A new species, Arthropteris samoensis (Arthropteridaceae), recorded from the Samoan islands of Upolu and Savai‘i, is described and illustrated. In Samoa, the new species is distinguished from Arthropteris palisotii s.l. by its smaller stature and more delicate texture (laminae mostly < 3 cm wide vs.

Patterns of Nucleotide Substitution in Angiosperm cpDNA trnL (UAA)–trnF (GAA) Regions [PDF]

Molecular Biology and Evolution, 2000
Patterns of substitution in chloroplast encoded trnL_F regions were compared between species of Actaea (Ranunculales), Digitalis (Scrophulariales), Drosera (Caryophyllales), Panicoideae (Poales), the small chromosome species clade of Pelargonium (Geraniales), each representing a different order of flowering plants, and Huperzia (Lycopodiales). In total,

Phylogenetic analysis and the recognition of a new genus for Mexican Crassulaceae segregated from Echeveria

TAXON, Volume 75, Issue 3, June 2026.
Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL, matK, rps16, ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 ...

Systematics of Parnassia (Celastraceae) inferred from plastid and nuclear DNA sequence data [PDF]

PhytoKeys
We presented a comprehensive phylogenetic analysis of Parnassia covering approximately 80% of recognized species. By integrating five plastid markers (rbcL, matK, rpl32-trnL, trnT-trnL and trnL-trnF) with nuclear marker ITS sequences and applying both ...

Testing robustness of relative complexity measure method constructing robust phylogenetic trees for Galanthus L. Using the relative complexity measure [PDF]

, 2013
Background: Most phylogeny analysis methods based on molecular sequences use multiple alignment where the quality of the alignment, which is dependent on the alignment parameters, determines the accuracy of the resulting trees.

ITS and trnL-F Sequences analysis of Potentilla discolor Bge. [PDF]

Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015
To provide scientific data of the internal transcribed spacer (ITS) and trnL-F sequences for the authentication of Potentilla discolor Bge., we extracted the genome DNA from the leaves of Potentilla discolor Bge., purchased from Hebei Province, amplified the ITS region using ITS universal primers of angiosperm, and sequenced the purified PCR products ...
