Phylogenomics and Biogeography of the Eastern Asian–Eastern North American Disjunct Genus Hylodesmum (Fabaceae)

open access: yesBiological Diversity, Volume 3, Issue 1, Page 14-32, March 2026.
Integrating data from plastid genomes, nrDNA, and 353 low‐copy nuclear genes, this study establishes a robust phylogenetic framework for Hylodesmum. This framework supports a taxonomic revision recognizing 18 species and reveals a complex pattern of bidirectional EA–ENA dispersal, with mammals as a plausible dispersal agent. ABSTRACT Phylogenomics with

Maternal origin, genome constitution and evolutionary relationships of polyploid Elymus species and Hordelymus europaeus

open access: yesBiologia Plantarum, 2011
The trnS/psbC region of chloroplast DNA (cpDNA) was sequenced for 18 Elymus polyploid species, Hordelymus europaeus and their putative diploid ancestors. The objective was to determine the maternal origin and evolutionary relationships of these polyploid

Extraction and analysis of high-quality chloroplast DNA with reduced nuclear DNA for medicinal plants

open access: yesBMC Biotechnology
Background Obtaining high-quality chloroplast genome sequences requires chloroplast DNA (cpDNA) samples that meet the sequencing requirements. The quality of extracted cpDNA directly impacts the efficiency and accuracy of sequencing analysis.

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

A Dynamic Tandem Repeat in Monocotyledons Inferred from a Comparative Analysis of Chloroplast Genomes in Melanthiaceae

open access: yesFrontiers in Plant Science, 2017
Chloroplast genomes (cpDNA) are highly valuable resources for evolutionary studies of angiosperms, since they are highly conserved, are small in size, and play critical roles in plants.
