Abstract Understanding plant diversity and the phylogenetic divergences in Northern Hemisphere is essential for in‐depth evolutionary studies conservation efforts. Maianthemum an ideal example to explore diversification processes Hemisphere, with more than 35 species widely distributed forests North Central America, Europe eastern Asia. Yet relationships within remain elusive. In this study, we reconstructed a well‐supported framework of explored possible gene introgressions reticulate evolution using nuclear chloroplast genomes based on target enrichment Hyb‐Seq approach. Both results supported three clusters corresponding their biogeographic distribution New World, Himalayan‐Hengduan Mountains, north temperate zone, respectively. The genus was inferred be most likely originated America migrations into Asia late Miocene. Our suggested that both incomplete lineage sorting hybridizations/introgressions along geographic isolation have contributed rapid divergence Asia, which may represent complex model radiation plants even Hemisphere.

ABSTRACT The genus Polygonatum boasts abundant germplasm resources and comprises numerous species. Among these, medicinal plants of this genus, which have a long history, garnered attention scholars. This study sequenced analyzed the chloroplast genomes six species ( P. zanlanscianense , kingianum sibiricum cyrtonema filipes odoratum respectively) to explore their interspecific relationships. sequence length (154, 578–155, 807 bp) genome structure were conserved among species, with typical tetrad structure. 127–131 genes contained in genomes, 84–85 are protein‐coding genes, 37–38 transfer RNA 6–8 ribosomal genes. 64–76 simple repeats (SSRs) 36–62 repetitive sequences. Codon bias patterns tended use codons ending A/T. In 30 types RSCU > 1, 93.3% ended A/T Twenty‐one highly variable plastid regions identified plants. Furthermore, phylogenetic analysis encompassing these 53 other revealed that clustered together on one clade, whereas formed separate clades. Notably, emerged as standalone our tree reinforces classification forming monophyly. provides novel basis for intragenus taxonomy DNA barcoding molecular identification within

The tribe Astereae (Asteraceae) includes 36 subtribes and 252 genera, is distributed worldwide in temperate tropical regions. One of the subtribes, Celmisiinae Saldivia, has been recently circumscribed to include six genera ca. 160 species, restricted eastern Australia, New Zealand, Guinea. species show an impressive range growth habit, from small herbs ericoid subshrubs medium-sized trees. They live a wide habitats are often dominant subalpine alpine vegetation. Despite well-supported circumscription Celmisiinae, uncertainties have remained about their internal relationships classification at genus levels. This study exploited recent advances high-throughput sequencing build robust multi-gene phylogeny for subtribe Celmisiinae. target enrichment Angiosperms353 bait set hybpiper-nf paragone-nf pipelines were used retrieve, infer, assemble orthologous loci 75 taxa representing all main putative clades within subtribe. Because diploidised ploidy level as well missing data assemblies, uncertainty remains surrounding inference orthology detection. However, based on variety gene-family sets, coalescent concatenation-based phylogenetic reconstructions recovered similar topologies. Paralogy gene-families caused some problems, but estimated phylogenies well-resolved. phylogenomic evidence supported three clades: Pleurophyllum clade (Pleurophyllum, Macrolearia Damnamenia), mostly Zealand Subantarctic Islands, Celmisia mainland Shawia (including 'Olearia pro parte' Pachystegia) Australia results presented here add accumulating support efficient method documenting plant diversity.

Background/Objectives: Polygonatum grandicaule Y.S.Kim, B.U.Oh & C.G.Jang (Asparagaceae Juss.), a Korean endemic species, has been described based on its erect stem, tubular perianth shape, and pedicel length. However, taxonomic status remains unclear due to limited molecular data. Methods: This study presents the complete plastid genomes (plastomes) of two P. individuals close relative, odoratum (Mill.) Druce var. thunbergii (C.Morren Decne.) H.Hara. Results: The plastomes, ranging from 154,578 154,579 base pairs (bp), are identical those falcatum A.Gray, odoratum, another infundiflorum C.G.Jang. All contain 78 protein-coding genes (PCGs), 30 tRNA genes, four rRNA except for pseudogene infA. Phylogenetic analyses using PCGs whole intergenic spacer (IGS) regions strongly support three sections within Mill. show that variety nested falcatum, grandicaule, infundiflorum. Conclusions: Given genomic variation phylogenetic relationships, we propose treating as part complex, despite their morphological differences. offers valuable putative markers species identification supports application plastome-based super-barcoding in morphologically diverse genus Polygonatum.

Target sequence capture (Hyb-Seq) is a cost-effective sequencing strategy that employs RNA probes to enrich for specific genomic sequences. By targeting conserved low-copy orthologs, Hyb-Seq enables efficient phylogenomic investigations. Here, we present Asparagaceae1726-a probe set 1726 nuclear genes phylogenomics in the angiosperm family Asparagaceae-which will aid often-challenging delineation and resolution of evolutionary relationships within Asparagaceae.
