TL;DR
This research established a feasible xylarium genomics approach by applying hybridization capture combined with next-generation sequencing to archived Fraxinus specimens, successfully retrieving high-quality plastid genomes with 99.89–100% coverage.
This study provides the first comprehensive phylogenetic framework for Stellaria based on the chloroplast genome, establishing a robust foundation for future taxonomic revisions and evolutionary studies.
12 plastomes representing major Mentha species, hybrid taxa, and unresolved accessions are analyzed to characterize plastome structure, repeat composition, sequence divergence, phylogenetic relationships, and plastid RNA editing.
This population-scale plastome dataset provides a practical reference for phylogeographic analysis, marker development, and conservation genomic studies in Cypripedium.
This plastome provides a valuable genomic resource and reveals robust discordance between morphology-based classification and plastid phylogenetic placement in F. gasparriniana, providing a foundation for future nuclear-genomic and population-level tests of the alternative evolutionary scenarios underlying this discordance.
Phylogenetic analyses recovered Veronica as a well-supported monophyletic lineage and clarified the plastid positions of the three newly sequenced species, providing plastome resources and molecular evidence for taxonomy, species identification, and future evolutionary studies of Veronica.
