    Untangling the origin and diversification of the Carthamus-Carduncellus complex(Cardueae,Compositae)in the Mediterranean basin

    查看更多>>摘要：Understanding the richness and diversification processes in the Mediterranean basin requires both knowledge of the current environmental complexity and paleogeographic and paleoclimate events and information from studies that introduce the temporal dimension.The Carthamus-Carduncellus complex(Cardueae,Compositae)constitutes a good case study to investigate the biogeographic history of this region because it evolved throughout the basin.We performed molecular dating,ancestral area estimation,and diversification analyses based on previous phylogenetic studies of a nearly complete taxon sampling of the complex.The main aims were to determine the role of tectonic and climatic events in the disjunction of the complex and the expansion route of the two main lineages,Carduncellus s.l.and Carthamus.Our results suggest that the main lineages in the complex originated during the Miocene.Later,all main paleogeographic and paleoclimatic events during the Neogene and Pleistocene in the Mediterranean basin had an important imprint on the evolutionary history of the complex.The Messinian Salinity Crisis facilitated the dispersion of the genus Carduncellus from North Africa to the Iberian Peninsula and the split of the genera Phonus and Femeniasia from the Carduncellus lineage.The onset of the Mediterranean climate in the Pliocene together with some orogenic processes could be the main causes of the diversification of the genus Carduncellus.In contrast,Pleistocene glaciations played a key role in the species diversification of Carthamus.In addition,we emphasize the problems derived from secondary dating and the existing differences between two previous dating analyses of the tribe Cardueae.

    Biogeographic analysis based on phylogenomic data supports multiple ancient dispersals that facilitated the eastern Asia-North America-Mexico disjunction in the subfamily Linnaeoideae(Caprifoliaceae)

    1025-1036页
    查看更多>>摘要：The small subfamily Linnaeoideae of Caprifoliaceae exhibits a disjunct distribution in Eurasia and North America,including Mexico,with most taxa occurring in eastern Asia or Mexico and the monospecific Linnaea Gronov.ex L.having a circumboreal to north temperate distribution.We sampled 17 of the 20 species representing all Linnaeoideae genera and used nuclear(target enrichment)and complete plastome sequence data to reconstruct the phylogeny.Our results show strong topological conflicts between nuclear and plastid data,especially concerning Dipelta Maxim.and Diabelia Landrein,supporting hybridization events complicating the deep diversification.Nuclear data were used for divergence time estimation and ancestral area reconstruction.The divergence time between the Mexican Vesalea M.Martens & Galeotti and the Linnaea clade was dated to 39.5 Ma,with a 95％highest posterior density of 28.2 Ma(mid-Oligocene)to 45.2 Ma(mid-Eocene).Reconstructed ancestral areas support a widespread common ancestor of Linnaea plus Vesalea in Mexico and at least another area(eastern Asia,North America,or Europe).The biogeographic analysis,including fossils,supports the ancestral range of Linnaeoideae to be widespread in central and western China+Europe+Mexico,or eastern and northern Asia+central and western China+Mexico,or central and western China+North America+Mexico.The North Atlantic and/or the Bering land bridges may be important in the widespread distribution across continents in the Northern Hemisphere.Our study highlights the importance of utilizing fossils in biogeographic inferences andusing data from different genomes while reconstructing deep and shallow phylogenies of organisms.

    Demographic complexity within walnut species provides insights into the heterogeneity of geological and climatic fluctuations in East Asia

    查看更多>>摘要：East Asia constitutes one of the largest and most complex areas of plant diversity globally.This complexity is attributable to the geological history and climatic diversity of East Asia.However,controversy persists over the biogeographical hypotheses and different studies on this topic.The demographical complexity of temperate deciduous woody plants and heterogeneity of geological and climatic fluctuations in East Asia remain poorly understood.We aimed to assemble the chloroplast and nuclear genomes of 360 individuals from five walnut(Juglans)species in East Asia and comprehensively analyze the phylogenetic inference,genetic structure,population demographic,and selection pressure.The results showed that East Asian walnuts could be divided into two major groups,that is,section Juglans/Dioscaryon and sect.Cardiocaryon.Within sect.Cardiocaryon,the samples were categorized into the northern clade and southern clade,both of which were affected by Quaternary glaciation;however,the southern clade was affected to a lesser extent.The population expansion events observed in sect.Cardiocaryon and sect.Dioscaryon since the late Miocene indicated that Neogene climate cooling substantially affected the distribution of Tertiary relict plants in East Asia.Biogeographic analysis results showed that the uplift of the Qinghai-Tibetan Plateau(QTP)might have contributed to the divergence within sect.Dioscaryon.Our findings highlight the heterogeneity of climatic fluctuations in the northern and southern regions of East Asia during the late Neogene and Quaternary periods and suggest that the uplift of QTP could have facilitated the divergence of temperate deciduous woody plants.

    Genetic formation of Sui populations in southwest China

    查看更多>>摘要：The Sui people living in Guizhou province have a unique ethnic culture and population history due to their long-time isolation from other populations.To investigate the genetic structure of Sui populations in different regions of Guizhou,we genotyped 89 individuals from four Sui populations using genome-wide single nucleotide polymorphisms arrays.We analyzed the data using principal component analysis,ADMIXTURE analysis,f-statistics,qpWave/qpAdm,TreeMix analysis,fineSTRUCTURE,and GLOBETROTTER.We found that Sui populations in Guizhou were genetically homogeneous and had a close genetic affinity with Tai-Kadai-speaking populations,Hmong-Mien-speaking Hmong,and some ancient populations from southern China.The Sui populations could be modeled as an admixture of 33.5％-37.9％of Yellow River Basin farmer-related ancestry and 62.1％-66.5％of Southeast Asian-related ancestry,indicating that the southward expansion of northern East Asian-related ancestry influenced the formation of the Tai-Kadai-speaking Sui people.Future publications of more ancient genomics in southern China could effectively provide further insight into the demographic history and population structure of the Sui people.
