Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds [PDF]

open access: yes, 2017
The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, organelle takeover by hybridization,

Characterization and Identification of Pulsatilla koreana and Pulsatilla tongkangensis Seedlings Based on Morphology, Colorimetric Data, and Molecular Markers

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
Pulsatilla tongkangensis, an endemic species growing in the limited areas in Korea, is considered endangered species, and is growing in sympatric with P. koreana enabling natural hybridization. To characterize the true to the type of P. tongkangensis, we integrated morphological traits and molecular analyses of the nuclear ribosomal ITS (nrITS) and the

Identification of three kinds of Plumeria flowers by DNA barcoding and HPLC specific chromatogram

open access: yesJournal of Pharmaceutical Analysis, 2018
DNA barcoding and HPLC specific chromatogram were used to identify three kinds of Plumeria flowers respectively. DNAs extracted from the three Plumeria species were amplified by PCR with universal primers, and the psbA-trnH region was selected.

Applying DNA Barcodes to Identify Closely Related Species of Ferns: A Case Study of the Chinese Adiantum (Pteridaceae). [PDF]

open access: yesPLoS ONE, 2016
DNA barcoding is a fast-developing technique to identify species by using short and standard DNA sequences. Universal selection of DNA barcodes in ferns remains unresolved. In this study, five plastid regions (rbcL, matK, trnH-psbA, trnL-F and rps4-trnS)

Herbariomics and the peculiar case of Alisma wahlenbergii (Alismataceae)

open access: yesTAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Species identification and delimitation in aquatic plants can be challenging due to their often simple, plastic, and convergent morphology. This has led to varying taxonomic opinions in many genera, including Alisma. One debated case is the narrowly endemic A. wahlenbergii, which occurs submerged in the Baltic Sea region.

An In Silico Approach for Evaluation of ITS, rbcL, and psbA-trnH for DNA Barcoding of Eugenia spp.

open access: yesBiosfer: Jurnal Tadris Biologi
The genus Eugenia is known to be complex with intricate synonyms and taxonomy, and morphological identification is often unreliable due to overlapping characteristics and environmental influences, particularly in the flowers.

Molecular and morphological analysis of subfamily Alooideae (Asphodelaceae) and the inclusion of chortolirion in aloe [PDF]

open access: yes, 2013
Asphodelaceae subfam. Alooideae (Asparagales) currently comprises five genera, four of which are endemic to southern Africa. Despite their importance in commercial horticulture the evolutionary relationships among the genera are still incompletely ...
