Abstract The genus Lonicera L. is widely distributed and well-known for its high species richness morphological diversity. Previous studies have suggested that many sections of are not monophyletic phylogenetic relationships within the still poorly known. In this study, we sampled 37 accessions , covering four subgenus Chamaecerasus plus six outgroup taxa to recover main clades based on sequences nuclear loci generated by target enrichment cpDNA from genome skimming. We found extensive cytonuclear discordance across subgenus. Both plastid analyses supported sister . Within Isika Niatoon were polyphyletic.

Ancestral area reconstruction indicate Qinghai Tibet Plateau (QTP) Asia, with subsequent dispersal other areas. aridification Asian interior possibly promoted rapid radiation region, uplift QTP appears triggered recent diversification adjacent regions. Overall, study provides new insights taxonomically complex lineages at level process speciation.

Abstract Background and Aims The staghorn fern genus Platycerium is one of the most commonly grown ornamental ferns, it evolved to occupy a typical pantropical intercontinental disjunction. However, species-level relationships in have not been well resolved, spatiotemporal evolutionary history also needs be explored. Methods Plastomes all 18 species were newly sequenced. Using plastome data, we reconstructed phylogenetic among Polypodiaceae members with focus on species, further conducted molecular dating biogeographical analyses genus. Key Results present yielded robustly supported hypothesis Platycerium. Molecular results showed that split from its sister Hovenkampia ~35.2 million years ago (Ma) near Eocene–Oligocene boundary began diverge ~26.3 Ma during late Oligocene, while multiple speciation events within occurred middle Miocene. Biogeographical analysis suggested originated tropical Africa then dispersed eastward southeast Asia–Australasia westward neotropical areas. Conclusions Our using plastid phylogenomic approach improved our understanding global climate changes both Late Oligocene Warming cooling following mid-Miocene Climate Optimum may promoted Platycerium, transoceanic long-distance dispersal plausible explanation for distribution today. study investigating provides case only formation disjunction this but ‘out Africa’ origin plant lineages.

Abstract Premise Biotic disjunctions have attracted scientific attention for the past 200 years. Despite being represented in many familiar plants (such as bald cypress, flowering dogwood, sweetgum, partridgeberry, etc.), eastern North American (ENA)–Mexican (M) disjunction remains poorly understood. Major outstanding questions include divergence times of taxa exhibiting and environmental/geological processes that may underlie disjunction. Symphyotrichum Nees (Asteraceae), one most diverse genera USA, displays several examples disjunct ENA–M taxa. Methods We generated target capture data using Angiosperms353 baitset first well‐sampled phylogenomic hypothesis its close relatives. Focusing on S . subgenus Virgulus , we used MCMC TREE to perform time estimation R package BioGeoBEARS infer ancestral regions biogeographic transitions between America Mexico. Finally, niche reconstruction method Utremi test a role historical aridification generating Results Our molecular suggest recent radiation at Plio‐Pleistocene boundary (~2.5 mya), with early connections Mexico lineages closed off shortly after were followed by vicariance across this region. Except some present‐day broadly distributed species, there is complete lack movement ENA M ~0.5 mya. Conclusions A reconstructed distribution suitable habitat Pleistocene climatic models corroborates results from modeling confirms glacial cycles are more likely be associated breakup connections.

Demonstrating the process of transregional biogeography and mechanisms underlying evolutionary radiations is crucial to understanding biological evolution. Here, we use Hydrangeeae (Hydrangeaceae), a tribe with unique disjunct distribution complex trait variations, using solid phylogenetic framework, investigate how geographical climatic factors interact functional traits trigger plant radiations. We constructed first highly supported dated framework 79 protein-coding genes obtained from 81 plastomes, representing 63 species all major clades, found that most extant originated asynchronous diversification two lineages undergoing repeated expansion retraction, at middle high latitudes Northern Hemisphere between East Asia North America, during Eocene Pleistocene (driven by geologic dynamics). In accordance these drivers, interactions flora central-eastern China Japan occurred frequently after Late Tertiary. resource limitation range fragmentation probably accelerated Hydrangeeae, which supports resource-use hypothesis. Our study sheds light on radiation assembly within Asia, Asian-North American disjunction, through integration phylogenomic biogeographic data ecological data.

Abstract Panax (Araliaceae) is a small genus containing several well known medicinally important species. It has disjunct distribution between Eastern Asia and North America, with most species from eastern Asia, especially the Himalayan‐Hengduan Mountains (HHM). This study used genomic target enrichment method to obtain 358 nuclear ortholog loci complete plastome sequences 59 accessions representing all 18 of genus. Divergence time estimation biogeographic analyses suggest that was probably widely distributed America during middle Eocene. During late Eocene Oligocene may have experienced extensive extinctions global climate cooling. survived diverged early in mountains Southwest China tropical Indochina, where some taxa migrated northwestward HHM, eastward central China, then onward toward Japan America. Gene flow identified as main contributor phylogenetic discordance (33.46%) within . We hypothesize common ancestors P. ginseng + japonicus quinquefolius clade had allopolyploidization, which increased adaptability cooler drier environments. Miocene, dispersals occurred region HHM contiguous areas, suggesting acted refugium also served secondary diversification center for Our findings highlight interplay orographic uplift climatic changes greatly contributed diversity

Abstract The discontinuous geographic distribution pattern of plants in the north temperate zone has been a focus biogeographic research, especially concerning mechanisms behind formation such and spatial temporal evolution this intermittent pattern. Hypotheses boreotropical origin, land bridge migration, out‐of‐Tibet have proposed to explain Lonicera shows typical Europe–Asia–North America distribution, which makes for good case study investigate above three hypotheses. In study, we inferred phylogeny based on plastid genomes nuclear data set with broad taxon sampling, covering 83 species representing two subgenera four sections. Both phylogenetic analyses found section Isika polyphyletic, while sections Nintooa , Isoxylosteum Coelxylosteum were monophyletic subgenus Chamaecerasus . Based chloroplast phylogeny, suggest transferring maximowiczii tangutica into Reconstruction ancestral areas suggests that originated Qinghai–Tibetan Plateau (QTP) and/or Asia, subsequently dispersed other regions. aridification Asian interior may facilitated rapid radiation region. At same time, uplifts Tibetan appear triggered spread recent diversification genus QTP adjacent areas. Overall, our results deepen understanding evolutionary history

Abstract Premise Glacial/interglacial cycles and topographic complexity are both considered to have shaped today's diverse phylogeographic patterns of taxa from unglaciated eastern North America (ENA). However, few studies focused on the phylogeography population dynamics wide‐ranging ENA herbaceous species occurring in forest understory habitat. We examined pattern evolutionary history Podophyllum peltatum L., a widely distributed herb inhabiting deciduous forests ENA. Methods Using chloroplast DNA (cpDNA) sequences nuclear microsatellite loci, we investigated structure genetic diversity species. Molecular dating, demographic analyses, ecological niche modeling were also performed illustrate patterns. Results Our cpDNA results identified three main groups that largely congruent with boundaries along Appalachian Mountains Mississippi River, two major geographic barriers Populations located east Appalachians central exhibited relatively higher levels diversity. Extant lineages may diverged during late Miocene, range expansions different happened Pleistocene glacial/interglacial cycles. Conclusions findings indicate started facilitate divergence P. before Pleistocene. Persistence multiple refugia, including areas around Quaternary glacial period, subsequent under hospitable climatic condition, especially westward expansion, likely responsible for species’ contemporary pattern.
