Characterization of Aster lautureanus (Asteroideae, Asteraceae) Chloroplast Genome and Phylogenetic Insights

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
In this study, we first sequenced and characterized the complete chloroplast genome of Aster lautureanus and conducted comprehensive analyses of genome structure, codon usage, repeat sequences, phylogeny, and divergence time. ABSTRACT The genus Aster represents an important group of flowering plants with complex evolutionary relationships, yet genomic ...

The Complete Plastid Genome of Astrohibiscus caesius (Hibisceae, Malvaceae) and Its Phylogenetic Placement

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
The complete plastid genome of Astrohibiscus caesius has a typical quadripartite structure (161,092 bp) and encodes 112 unique genes with an AT‐rich bias. Phylogenomic analysis confirms that Hibiscus is polyphyletic and Astrohibiscus forms a distinct lineage outside all major Hibiscus clades, providing whole‐plastome evidence supporting this monotypic ...

Molecular Phylogenetic Studies of Korean Calystegia R.Br. Based on ITS and psbA-trnH Sequences

open access: yesKorean Journal of Plant Taxonomy, 2011
Molecular phylogenetic studies were conducted to evaluate evolutionary trends, relationships and species identities among four species, one variety and one outgroup of the Korean Genus Calystegia. The important characteristics of Calystegia are the shape of the lamina, the length ofthe corolla and the presence of hair.

Pilosella bauhinii (Schult.) Arv.-Touv. and P. cymosa subsp. vaillantii (Tausch) S. Bräut. & Greuter (Asteraceae) from new localities in north-central Poland

open access: yesActa Societatis Botanicorum Poloniae, 2015
We provide information about two species, Pilosella bauhinii and P. cymosa subsp. vaillantii (Asteraceae), from new localities in north-central Poland (ATPOL DC18). All individuals of both species grew on a railway embankment in Górzno-Lidzbark Landscape

Plastome Evolution and Codon Usage Dynamics in Argentina (Rosaceae): Phylogenomic Resolution and Adaptive Signatures

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This study assembled chloroplast genomes for three Argentina species and compared them with 15 others to resolve long‐standing taxonomic issues. Phylogenomic analyses strongly supported the monophyly of Argentina and identified five major clades, while analyses of codon usage revealed that natural selection is the predominant force shaping codon ...

Genetic variation of Kaempferia (Zingiberaceae) in Thailand based on chloroplast DNA(psbA-trnH and petA-psbJ) sequences

open access: yesGenetics and Molecular Research, 2010
Genetic variation and species authentication of 71 Kaempferia accessions (representing 15 recognized, six new, and four unidentified species) found indigenously in Thailand were examined by determining chloroplast psbA-trnH and partial petA-psbJ spacer sequences. Ten closely related species (Boesenbergia rotunda, Gagnepainia godefroyi, G.

Comparing Accuracy and Biases of DNA Metabarcoding, Hybridization Capture, and Metagenomic Sequencing for Quantifying Herbivore Diets

open access: yesMolecular Ecology Resources, Volume 26, Issue 5, July 2026.
ABSTRACT DNA metabarcoding using relative read abundance (RRA) is commonly applied to estimate herbivore diet composition, yet its quantitative accuracy remains uncertain. We assessed taxonomic resolution and quantitative performance of RRA from DNA metabarcoding compared to metagenomic sequencing and hybridization capture, using deer scats from ...
