We investigated Viburnum phylogeny using separate and combined analyses of DNA sequence data from two chloroplast and three nuclear loci. Separate analyses of nuclear and chloroplast data sets resulted in gene trees that were generally congruent with one another and with trees from two previous analyses. Our gene trees do differ in the position of section Pseudotinus, as well as in species relationships within sections Pseudotinus and Lentago. However, tests for incongruence indicate that… 
A chloroplast tree for Viburnum (Adoxaceae) and its implications for phylogenetic classification and character evolution.
TLDR
The value of next-generation plastid sequencing, the ease of creating a formal phylogenetic classification, and the utility of such a system in describing patterns of character evolution are demonstrated.
Dissolution of Viburnum Section Megalotinus (Adoxaceae) of Southeast Asia and Its Implications for Morphological Evolution and Biogeography
This study marks a significant increase in the number of species and genetic loci used in reconstructing the phylogeny of Viburnum. In particular, we expanded sampling of the morphologically
Phylogenetics and genomic patterns of speciation in Pinus with an empahsis on subgenus Strobus
TLDR
It is demonstrated that Pinus chiapensis is a distinct species, but that taxonomy is not universally accepted, and the absence of allelic coalescence is a severe constraint in the application of phylogenetic methods in Pinus.
Toward a resolution of Campanulid phylogeny, with special reference to the placement of Dipsacales
TLDR
These analyses support the monophyly of the four major clades and the relationships among them, andAsterales are inferred to be sister to a clade containing Apiales and Dipsacales, which is consistent with more weakly supported results from previous studies.
Widespread genealogical nonmonophyly in species of Pinus subgenus Strobus.
TLDR
It is felt that incomplete lineage sorting remains the best explanation for the polymorphisms shared among species, and taxa sharing similar life history traits with Pinus are likely to show species nonmonophyly using nuclear markers.
Phylogenetic and Comparative Analyses of Complete Chloroplast Genomes of Chinese Viburnum and Sambucus (Adoxaceae)
TLDR
Describing the complete chloroplast genomes of 21 Viburnum species endemic to China, as well as three Sambucus species, shows the power of the complete cp genomes in improving phylogenetic resolution, and will contribute to a better understanding of plastome evolution in Chinese Adoxaceae.
Phylogeny and biogeography of Cedrus (Pinaceae) inferred from sequences of seven paternal chloroplast and maternal mitochondrial DNA regions.
TLDR
The results indicate that Cedrus could have an origin in the high latitude area of Eurasia, and its present distribution might result from vicariance of southerly migrated populations during climatic oscillations in the Tertiary and further fragmentation and dispersal of these populations.
Phylogeny of the Linnaea clade: are Abelia and Zabelia closely related?
TLDR
A molecular investigation including nine Abelia and five Zabelia species based on nuclear (ITS) and plastid sequence data indicates that Abelia is paraphyletic and possibly polyphyletic, and support for a monophyletic Linnaea clade without ZabelIA is strong.
Evolution and Phylogenetic Importance of Endocarp and Seed Characters in Viburnum (Adoxaceae)
TLDR
The results largely agree with the results based on molecular data and provide several additional insights on character evolution and the position of V. clemensae as sister to the rest of Viburnum is supported by several characters.
Taxonomy, phylogeny and host plants of some Abia sawflies (Hymenoptera, Cimbicidae).
TLDR
Based on the species here sampled, phylogenetic tree reconstructions inferred from three (nuclear and mitochondrial) genes of some West Palaearctic and Nearctic species strongly support a clade recognised widely in earlier literature as Abia or Abia (Abia), but do not always support another clade, Zaraea or Aba (Zaraea), as monophyletic.

Viburnum phylogeny: evidence from the duplicated nuclear gene GBSSI.
TLDR
The GBSSI trees confirm the monophyly of some and non-monophyle of other traditionally recognized taxonomic sections, the presence of three major supra-sectional lineages within Viburnum, and the resolution of many species relationships within the section-level clades.
Testing for Phylogenetic Conflict Among Molecular Data Sets in the Tribe Triticeae (Gramineae)
TLDR
Test results show no evidence for significant differences in the phylogenetic signal among the three nuclear data sets, with the exception of the placement of a single taxon.
DIPSACALES PHYLOGENY BASED ON CHLOROPLAST DNA SEQUENCES
TLDR
Dipsacales in the traditional sense is a monophyletic g roup and Triplostegia is more closely related to Dipsacaceae than it is to Valerianaceae, and confidence in most major clades is now very high.

Dating the Dipsacales: comparing models, genes, and evolutionary implications.
TLDR
A wide range of divergence times that can be obtained using different methods and data sets is demonstrated, and cautions against reliance on age estimates based on only a single gene or methodology.

The most important conclusions of this analysis are that the New World Sect.
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.
Assessing Congruence: Empirical Examples from Molecular Data
TLDR
Although it is readily apparent that multiple data sets are needed for estimating phylogenetic relationships reliably, it is also recognized that different genes may, in fact, possess different branching histories (see Chapter 10).
The Evolution of Reproductive Characters in Dipsacales
TLDR
Improved knowledge of Dipsacales phylogeny provides a solid framework for studies of character evolution, and modifications of the epicalyx parallel those of the ovary and calyx within Valerianaceae, suggesting a transference of function involving homeoheterotopy.
