Analysis of sequence data for the chloroplast encoded genes rbcL and matK for 40 taxa representing all conifer families and subfamilies, rooted on Ginkgo biloba, provides robust support for the family concepts of Araucariaceae, Cupressaceae sensu lato, Pinaceae and Sciadopilyaceae. Whereas Phyllocladus and Cephalotaxus are robustly linked with, but separated from Podocarpaceae sensu stricto and Taxaceae, respectively, these distinctions decay at far fewer steps (+3.7 and +1.7 steps… Expand

Figures and Tables from this paper

Interspecific relationships and origins of Taxaceae and Cephalotaxaceae revealed by partitioned Bayesian analyses of chloroplast and nuclear DNA sequences
TLDR
The results confirm, on a basis of multiple molecular markers and a complete sampling of basic species, the suggested monophyly of Taxaceae and Cephalotaxaceae and propose interspecific relationships within each group, with profound nomenclatural and taxonomic implications. Expand
Inference of higher-order conifer relationships from a multi-locus plastid data set
TLDR
The broad backbone of conifer phylogeny is reconstructed from a survey of 15–17 plastid loci and associated noncoding regions from exemplar conifer species, and the deepest phylogenetic split is inferred to be between Pinaceae and all other conifers (Cupressophyta). Expand
Interspecific Relationships and Origins of Taxus and Cephalotaxus

TLDR
The results propose interspecies relationship within each group, with profound nomenclatural and taxonomic implications, and combination of partitioned Bayesian analysis and likelihood-based methods produced a more robust phylogenetic hypothesis for the two studied families. Expand
Evolution and biogeography of the austral genus Phyllocladus (Podocarpaceae)
TLDR
Phyllocladus forms a distinct lineage that diverged early in the evolutionary history of Podocarpaceae, and the fossil record indicates that the genus was more widely distributed and morphologically diverse during the early Tertiary than at present. Expand
Relationships within Podocarpaceae based on DNA sequence, anatomical, morphological, and biogeographical data
Despite considerable recent progress in understanding intergeneric relationships, a comprehensive analysis of Podocarpaceae at the species level using molecular data, biogeography, anatomy, andExpand
Phylogenetic Analysis of Araucariaceae: Integrating Molecules, Morphology, and Fossils
TLDR
A strongly supported and well-resolved phylogeny of Araucariaceae that includes both living species and fossil species for the group is obtained and shows the feasibility and usefulness of phylogenetic analyses that incorporate multiple sources of evidence. Expand
Use of Simultaneous Analyses to Guide Fossil‐Based Calibrations of Pinaceae Phylogeny
TLDR
It is demonstrated that simultaneous phylogenetic analyses of chloroplast DNA (matK and rbcL) and nonmolecular characters that include both extant genera and a limited number of fossil taxa provide useful hypotheses for calibrating molecular trees. Expand
Plastome phylogenomics of Cephalotaxus (Cephalotaxaceae) and allied genera
TLDR
The results justify the taxonomic proposal that recognizes Cephalotaxaceae as a monotypic family, and contribute to a clear-cut delineation between Cep Halotaxus and Taxaceae. Expand
Three genome-based phylogeny of Cupressaceae s.l.: further evidence for the evolution of gymnosperms and Southern Hemisphere biogeography.
TLDR
Two single-copy nuclear genes are used, together with chloroplast and mitochondrial genes, to reconstruct the phylogeny of the ecologically-important conifer family Cupressaceae s.l., based on a complete sampling of its 32 genera, and the biogeographic history of Cupressus, Fitzroya and Sequoia is found.

TLDR
Results and developmental genetic data are consistent with homology of the angiosperm bitegmic ovule with the cupule of glossopterids and Caytonia, while the carpel could represent a leaf and a cupule‐bearing axillary branch in living basal angiosperms. Expand

Generic relationships within and between the gymnosperm families Podocarpaceae and Phyllocladaceae based on an analysis of the chloroplast gene rbcL.
TLDR
The results indicate that Podocarpaceae are polyphyletic unless expanded to include Phyllocladaceae, and jackknife support values indicate that although the genera are well supported, relationships both within and between them are not, suggesting that intergeneric relationships in the family require further study.

Phylogenetic Relationships among the Genera of Taxodiaceae and Cupressaceae: Evidence from rbcL Sequences
TLDR
Phylogenetic analyses produced four most parsimonious trees that differ only in the positions of three genera and the degree of resolution of a trichotomy within Cupressaceae s.l. str. Expand
Phylogenetic relationships of conifers inferred from partial 28S rRNA gene sequences.
TLDR
Cl cladistic analyses using a new data set obtained from 28S rRNA gene sequences strongly support the monophyly of conifers including Taxaceae and suggest that the common ancestor of these families, both having the greatest diversity in the Southern Hemisphere, inhabited Gondwanaland. Expand
Relationships within Cupressaceae sensu lato: a combined morphological and molecular approach.
TLDR
Parsimony analysis of matK and rbcL sequence data, together with a nonmolecular database, yielded a well-resolved phylogeny of Cupressaceae sensu lato, and a new infrafamilial classification is proposed in which seven subfamilies are recognized. Expand

TLDR
Inferences of plesiomorphic character states within the family are largely consistent between analyses and support the view that prototypical podocarps had bifacial leaves, cones with several fertile cone scales, and large epimatia (cone scales) that covered the inverted ovules. Expand
Phylogeny of taxaceae and cephalotaxaceae genera inferred from chloroplast matK gene and nuclear rDNA ITS region.
TLDR
The results refute the views that Cephalotaxaceae has no alliance with Taxaceae and that Austrotaxus and Amentotaxus should be excluded from the Taxaceae, and do not support Florin's claim that taxads could be traced to Devonian psilophytes. Expand
Phylogenetic relationships within Araucariaceae based on rbcL gene sequences.
TLDR
Phylogenetic trees determined by the parsimony method indicate that Araucariaceae are well defined by rbcL sequences and also that the monophyly of Agathis or Araucaria is well supported by high bootstrap values. Expand
Phylogenetic assessment of the monotypic genera Sundacarpus and Manoao (Coniferales: Podocarpaceae) utilising evidence from 18S rDNA sequences
TLDR
A phylogenetic assessment of the monotypic genera Sundacarpus and Manoao was conducted employing maximum parsimony the analysis of sequence data from 18S-ribosomal DNA from 34 gymnosperm taxa, finding high bootstrap support for Podocarpaceae, but the order of deep branches within the family is equivocal.

The evolutionary split of Pinaceae from other conifers: evidence from an intron loss and a multigene phylogeny.
TLDR
The data suggest that the non-Pinaceae conifers represent a monophyletic group, in agreement with the conclusion from other recent molecular phylogenetic studies that refute the anthophyte hypothesis. Expand
Seed Plant Phylogeny and the Relationships of Gnetales

TLDR
Results imply that glossophytes originally had glossopterid-like leaves and bract-sporophyll complexes, which were transformed into carpels with bitegmic ovules in angiosperms, but reduced to single, terminal Ovules in Gnetales; flowers arose independently in the two lines. Expand
