    • The establishment of Central American migratory corridors and the biogeographic origins of seasonally dry tropical forests in Mexico 

      Willis, Charles G.; Franzone, Brian F.; Xi, Zhenxiang; Davis, Charles C. (Frontiers Media S.A., 2014)
      Biogeography and community ecology can mutually illuminate the formation of a regional species pool or biome. Here, we apply phylogenetic methods to a large and diverse plant clade, Malpighiaceae, to characterize the ...

    • Estimating phylogenetic trees from genome-scale data 

      Liu, Liang; Xi, Zhenxiang; Wu, Shaoyuan; Davis, Charles Cavender; Edwards, Scott V. (Wiley-Blackwell, 2015)
      The heterogeneity of signals in the genomes of diverse organisms poses challenges for traditional phylogenetic analysis. Phylogenetic methods known as “species tree” methods have been proposed to directly address one ...

    • Horizontal transfer of expressed genes in a parasitic flowering plant 

      Xi, Zhenxiang; Bradley, Robert K; Wurdack, Kenneth J; Wong, KM; Sugumaran, M; Bomblies, Kirsten; Rest, Joshua S; Davis, Charles Cavender (BioMed Central, 2012)
      Background: Recent studies have shown that plant genomes have potentially undergone rampant horizontal gene transfer (HGT). In plant parasitic systems HGT appears to be facilitated by the intimate physical association ...

    • Massive Mitochondrial Gene Transfer in a Parasitic Flowering Plant Clade 

      Xi, Zhenxiang; Wang, Yuguo; Bradley, Robert K.; Sugumaran, M.; Marx, Christopher J; Rest, Joshua S.; Davis, Charles Cavender (Public Library of Science, 2013)
      Recent studies have suggested that plant genomes have undergone potentially rampant horizontal gene transfer (HGT), especially in the mitochondrial genome. Parasitic plants have provided the strongest evidence of HGT, which ...

    • Phylogenomics and Coalescent Analyses Resolve Extant Seed Plant Relationships 

      Xi, Zhenxiang; Rest, Joshua S.; Davis, Charles C. (Public Library of Science, 2013)
      The extant seed plants include more than 260,000 species that belong to five main lineages: angiosperms, conifers, cycads, Ginkgo, and gnetophytes. Despite tremendous effort using molecular data, phylogenetic relationships ...

    • Phylogeny of the Clusioid Clade (Malpighiales): Evidence from the Plastid and Mitochondrial Genomes 

      Ruhfel, Brad R; Bittrich, Volker; Bove, Claudia P.; Gustafsson, Mats H. G.; Philbrick, C. Thomas; Rutishauser, Rolf; Xi, Zhenxiang; Davis, Charles Cavender (Botanical Society of America, 2011)
      Premise of the study: The clusioid clade includes five families (i.e., Bonnetiaceae, Calophyllaceae, Clusiaceae s.s., Hypericaceae, and Podostemaceae) represented by 94 genera and ∼1900 species. Species in this clade form ...

    • Plastid phylogenomics and green plant phylogeny: almost full circle but not quite there 

      Davis, Charles C; Xi, Zhenxiang; Mathews, Sarah (BioMed Central, 2014)
      A study in BMC Evolutionary Biology represents the most comprehensive effort to clarify the phylogeny of green plants using sequences from the plastid genome. This study highlights the strengths and limitations of plastome ...
