DNA Barcoding of the Endangered Aquilaria (Thymelaeaceae) and Its Application in Species Authentication of Agarwood Products Traded in the Market.

open access: yesPLoS ONE, 2016
The identification of Aquilaria species from their resinous non-wood product, the agarwood, is challenging as conventional techniques alone are unable to ascertain the species origin.

The discovery of a new locality for Aldrovanda vesiculosa (Droseraceae), a critically endangered free-floating plant in Japan

open access: yesJournal of Asia-Pacific Biodiversity, 2023
Aldrovanda vesiculosa L. is a globally endangered aquatic plant, with only two reintroduced populations known in Japan. In October 2022, we found a population of this species with nearly 10,000 individuals in an agricultural pond in Ishikawa Prefecture ...

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

open access: yes, 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 ...

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]

open access: yesAnnals 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

A new combination and typification of Pouzolzia peteri Friis (Urticaceae)

open access: yesNordic Journal of Botany, EarlyView.
Pouzolzia peteri, a lesser‐known species from the African continent, is currently classified as a member of the genus Pouzolzia. However, based on the morphological characteristics of its male flowers and leaf venation, its transfer to the genus Gonostegia is proposed.

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]

open access: yes, 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.

Phylogeny and historical biogeography of Lauraceae [PDF]

open access: yes, 2000
Phylogenetic relationships among 122 species of Lauraceae representing 44 of the 55 currently recognized genera are inferred from sequence variation in the chloroplast and nuclear genomes.

Reinstatement of the name Anisochilus eriocephalus Benth. (Lamiaceae) supported by micromorphological and molecular data

open access: yesNordic Journal of Botany, EarlyView.
In 2019, A. J. Paton et al. proposed a new taxonomic combination, transferring Anisochilus carnosus (L.f.) Wall. ex Benth. to Coleus strobilifer (Benth.) A.J.Paton, and including Anisochilus eriocephalus Benth. within this broader circumscription.

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]

open access: yesInternational 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.
