Evolution of Eastern Asian and Eastern North American Disjunct Distributions in Flowering Plants
TLDR
Phylogenetic, molecular, geologic, and fossil data all support the hypothesis that the eastern Asian and eastern North American disjunct distributions are relicts of the maximum development of temperate forests in the northern hemisphere. Expand
Phylogeny and biogeography of Panax L. (the ginseng genus, araliaceae): inferences from ITS sequences of nuclear ribosomal DNA.
  • J. Wen, E. Zimmer
  • Biology, Medicine
  • Molecular phylogenetics and evolution
  • 1 October 1996
TLDR
The Himalayas and central and western China are the current centers of diversity of the ginseng genus and the low ITS sequence divergence and a close relationship among species in that region suggest that rapid evolutionary radiation may have created such a diversity of Panax in the Himalaya and in central and eastern China. Expand
Evolutionary diversifications of plants on the Qinghai-Tibetan Plateau
The Qinghai-Tibetan Plateau (QTP) is the highest and one of the most extensive plateaus in the world. Phylogenetic, phylogeographic, and ecological studies support plant diversifications on the QTP… Expand
Infrafamilial classifications and characters in Araliaceae: Insights from the phylogenetic analysis of nuclear (ITS) and plastid (trnL-trnF) sequence data
TLDR
Parsimony and Bayesian-inference analyses suggest that there are three major lineages of Araliaceae, and that these lineages generally correspond with the centers of diversity for the family. Expand
A phylogenetic analysis of Prunus and the Amygdaloideae (Rosaceae) using ITS sequences of nuclear ribosomal DNA.
  • S. Lee, J. Wen
  • Biology, Medicine
  • American journal of botany
  • 2001
TLDR
The analyses suggest two major groups within the Amygdaloideae: PRUNUS: s.l. (sensu lato) and MADDENIA:, and (2) EXOCHORDA:, Oemleria, and PRINSEPIA: The ITS phylogeny supports the recent treatment of including EXO CHORDA: (formerly in the Spiraeoideae) in the Amydraesideae. Expand
Phylogenetic analysis of the grape family (Vitaceae) based on three chloroplast markers.
TLDR
Phylogenetic analysis of the combined data provided a fairly robust phylogeny for Vitaceae, which shows complex multiple intercontinental relationships within the northern hemisphere and between northern and southern hemispheres. Expand
Phylogenetic and biogeographic complexity of Magnoliaceae in the Northern Hemisphere inferred from three nuclear data sets.
  • Z. Nie, J. Wen, +5 authors E. Zimmer
  • Biology, Medicine
  • Molecular phylogenetics and evolution
  • 1 September 2008
TLDR
A relaxed clock relying on uncorrelated rates suggests that the complicated divergent evolution of Magnolioideae began around the early Eocene (54.57mya), concordant with paleoclimatic and fossil evidence. Expand
Molecular phylogeny of Salix L. (Salicaceae) inferred from three chloroplast datasets and its systematic implications
Salix is a taxonomically difficult genus and its generic limits and infrageneric division are still highly controversial. We employed sequences of the chloroplast rbcL gene, trnD-T spacer and… Expand
The Evolution of Araliaceae: A Phylogenetic Analysis Based on ITS Sequences of Nuclear Ribosomal DNA
TLDR
Phylogenetic analyses of ITS sequence data do not support the widely used traditional division of Araliaceae into three tribes, and topologies suggest that biogeographic radiations into different tropical/subtropical regions and into the north and south temperate regions occurred early in the history of core Arali growers. Expand
Biogeographic diversification in Nolana (Solanaceae), a ubiquitous member of the Atacama and Peruvian Deserts along the western coast of South America
TLDR
Recon reconstructs the biogeographic diversification for Nolana L.f. (Solanaceae), a genus of 89 endemic species largely restricted to fog‐dependent desert lomas formations of coastal Peru and Chile, to suggest rapid adaptive radiation in several clades. Expand
