Abstract Hemlock, Tsuga (Pinaceae), has a disjunct distribution in North America and Asia. To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two western North American species, T. heterophylla and T. mertensiana, and a clade of Asian… Expand
Molecular phylogeny and biogeography of Pseudotsuga (Pinaceae): insights into the floristic relationship between Taiwan and its adjacent areas.
TLDR
It is suggested that Pseudotsuga might have originated from North America and then migrated to eastern Asia by the Bering land bridge during the early Miocene, and Taiwan is closely related to both southwest and east China in flora. Expand
A New Species and Introgression in Eastern Asian Hemlocks (Pinaceae: Tsuga)
TLDR
Divergent topologies suggest chloroplast capture of T. chinensis by Japanese T. sieboldii and Ulleungdo hemlocks are distinct from other northeastern Asian species in leaf and cone morphology and phenologically in common-garden observations, and are described as a new species, T. ulleungensis. Expand
Biogeography of North Pacific Isoëtes (Isoëtaceae) inferred from nuclear and chloroplast DNA sequence data
TLDR
This study identifies the biogeographic origin of the North Pacific Isoëtes and suggests long-distance dispersal as the most likely explanation for their intercontinental distribution. Expand
Phylotranscriptomics reveals the complex evolutionary and biogeographic history of the genus Tsuga with an East Asian-North American disjunct distribution.
TLDR
The results of phylogenetic analysis, molecular dating and ancestral area reconstruction indicate that Tsuga very likely originated from North America in the late Oligocene and dispersed from America to East Asia via the Bering Land Bridge during the middle Miocene, and found complex reticulate evolutionary pattern among the East Asian hemlock species. Expand
Phylogenetic analysis of eastern Asian and eastern North American disjunct Lespedeza (Fabaceae) inferred from nuclear ribosomal ITS and plastid region sequences
TLDR
Phylogenetic relationships among Lespedeza species and related taxa were inferred from nuclear ribosomal internal transcribed spacer and plastid sequences, and it was revealed that the genus Campylotropis is sister to the other two genera. Expand
Phylogenetic relationships, possible ancient hybridization, and biogeographic history of Abies (Pinaceae) based on data from nuclear, plastid, and mitochondrial genomes.
TLDR
Results from biogeographic analyses and divergence time estimation suggested an origin and early diversification of Abies in an area of high latitude around the Pacific during the Eocene and an 'out-of-America' migration, for the origin of an eastern Asian and western North American disjunct species pairs in section Amabilis. Expand
Reexamination of the pattern of geographical disjunction of Chamaecyparis (Cupressaceae) in North America and East Asia.
TLDR
A dispersal-vicariance analysis, and geologic and fossil evidence indicated that at least two independent dispersal events occurred from North America to East Asia, which support the previous biogeographic inference by ptDNA. Expand
The Phylogeny and Biogeographic History of Ashes (Fraxinus, Oleaceae) Highlight the Roles of Migration and Vicariance in the Diversification of Temperate Trees
TLDR
The cosmopolitan genus Fraxinus, which comprises about 40 species of temperate trees and shrubs occupying various habitats in the Northern Hemisphere, represents a useful model to study speciation in long-lived angiosperms and molecular dating suggested that the initial divergence of the taxonomical sections occurred during the middle and late Eocene and Oligocene periods. Expand
Whole chloroplast genome sequences of the Japanese hemlocks, Tsuga diversifolia and T. sieboldii, and development of chloroplast microsatellite markers applicable to East Asian Tsuga
TLDR
The high transferability of these loci, and the fact that all species contained loci with non-overlapping allele size ranges, indicates that these markers will be useful for genetic studies of all East Asian Tsuga species for investigating species boundaries, phylogeography and stand-level processes. Expand
Insights from Chloroplast DNA into the Progenitor-Derivative Relationship Between Campanula punctata and C. takesimana (Campanulaceae) in Korea
TLDR
This study pinpoints a very narrow geographical source area and suggests the potentially important role of Dokdo Island as an initial stepping stone for Ulleung Island endemics and finds substantially lower genetic diversity statistics for C. takesimana compared to its progenitor. Expand

Molecular phylogeny and biogeography of Picea (Pinaceae): implications for phylogeographical studies using cytoplasmic haplotypes.
TLDR
It is suggested that Picea originated in North America, and that its present distribution could stem from two times of dispersal from North America to Asia by the Beringian land bridge, and then from Asia to Europe. Expand
Recolonization and radiation in Larix (Pinaceae): evidence from nuclear ribosomal DNA paralogues
TLDR
This study suggests that the distribution pattern analysis of members of multiple gene family would be very useful in tracking the evolutionary history of some taxa with recent origin or rapid radiation that cannot be resolved by other molecular markers. Expand
A phylogeny of cycads (Cycadales) inferred from chloroplast matK gene, trnK intron, and nuclear rDNA ITS region.
TLDR
According to the phylogenies, the past geography of the genera of cycads and the evolution of character states are hypothesized and discussed, and within the suborder Zamiieae, Stangeria, and the tribe Zamieae evolved significantly faster than other genera. Expand
Phylogeny and biogeography of Valerianaceae (Dipsacales) with special reference to the South American valerians
TLDR
Estimates suggest that Valerianaceae colonized South America prior to the formation of the Isthmus of Panama, and indicate that Plectritis is nested within South American Valeriana, as opposed to being sister to Centhranthus as previously hypothesized. Expand
Phylogenetics of Pinus (Pinaceae) based on nuclear ribosomal DNA internal transcribed spacer region sequences.
TLDR
A 650-bp portion of the nuclear ribosomal DNA internal transcribed spacer region was sequenced in 47 species of Pinus, representing all recognized subsections of the genus, and 2 species of Picea and Cathaya as outgroups, highlighting taxa of particularly problematic placement including Pinus nelsonii and P. aristata. Expand
Internal transcribed spacer region evolution in Larix and Pseudotsuga (Pinaceae).
TLDR
The phylogenetic hypothesis did not conflict with a stepping stone model of evolution for Pseudotsuga, but a basal lineage could not be inferred for either genus and a slow rate of concerted evolution among nrDNA loci was suggested. Expand
Variation in the nrDNA ITS of Pinus subsection Cembroides: implications for molecular systematic studies of pine species complexes.
TLDR
Within the pinyon clade, phylogenetic structure is present, but different clones from the same (or different) individuals of a species are polyphyletic, indicating that coalescence of ITS copies within individual genomes predates evolutionary divergence in the group. Expand
Chloroplast DNA phylogeny, reticulate evolution, and biogeography of Paeonia (Paeoniaceae).
TLDR
A refined hypothesis of species phylogeny of section Paeonia was proposed by considering the discordance between the nuclear and cpDNA phylogenies to be results of hybrid speciation followed by inheritance of cpDNA of one parent and fixation of ITS sequences of another parent. Expand
Marked Intragenomic Heterogeneity and Geographical Differentiation of nrDNA ITS in Larixpotaninii (Pinaceae)
Nuclear ribosomal DNA (nrDNA) of gymnosperms, especially Pinaceae, is characterized by slow concerted evolution and exhibits substantial ITS-region length variation (975–3663 bp), in sharp contrastExpand
Phylogeny and divergence times in Pinaceae: evidence from three genomes.
TLDR
Intergeneric relationships of Pinaceae using sequences of the chloroplast matK gene, the mitochondrial nad5 gene, and the low-copy nuclear gene 4CL are studied to suggest morphology of both vegetative and reproductive organs has undergone convergent evolution within the pine family. Expand
