TLDR
The joint usage ofrps16 intron and ITS sequences provides a powerful tool for resolving many of the difficult taxonomic issues in the tribeSileneae.
Abstract
Intron sequences of the chloroplast generps16 from 46 species were used to examine phylogenetic relationships indicated by nrDNA ITS sequence variation in the tribeSileneae (Caryophyllaceae, Caryophylloideae). This region has previously not been utilized for phylogenetic purposes but the results presented here suggest that it is a consistent and valuable complement to the ITS sequences. Therps16 intron trees are largely congruent with the ITS trees. All the major hypotheses suggested by the ITS data are supported, often at similar bootstrap levels. The joint usage ofrps16 intron and ITS sequences provides a powerful tool for resolving many of the difficult taxonomic issues in the tribeSileneae.

The tortoise and the hare II: relative utility of 21 noncoding chloroplast DNA sequences for phylogenetic analysis

TL;DR: The results of this study show that a survey using as few as three representative taxa can be predictive of the amount of phylogenetic information offered by a cpDNA region and that rate heterogeneity exists among noncoding cpDNA regions.

Phylogenetics of asterids based on 3 coding and 3 non-coding chloroplast DNA markers and the utility of non-coding DNA at higher taxonomic levels

TL;DR: The analysis has contributed to reclassification of several families, e.g., Tetrameristaceae, Ebenaceae, Styracaceae, Montiniaceae, Orobanchaceae, and Scrophulariaceae (by inclusion of Pellicieraceae, Lissocarpaceae, Halesiaceae, Kaliphoraceae, Cyclocheilaceae, respectively), and to the placement of families that were unplaced in the APG-system.

Multiple origins of crassulacean acid metabolism and the epiphytic habit in the Neotropical family Bromeliaceae

TL;DR: A phylogenetic analysis of nucleotide sequences for 51 bromeliad taxa indicated that the last common ancestor of Bromeliaceae was a terrestrial C(3) mesophyte, probably adapted to moist, exposed, nutrient-poor habitats.
Journal ArticleDOI

The evolution of antiherbivore defenses and their contribution to species coexistence in the tropical tree genus Inga

TL;DR: In an analysis of community assembly, it is found that Inga species co-occurring as neighbors are more different in antiherbivore defenses than random, suggesting that possessing a rare defense phenotype increases fitness.
Journal ArticleDOI

Patterns of reproductive isolation in three angiosperm genera

TL;DR: Results suggest that changes in ploidy disrupt a simple monotonic relationship between isolation and genetic distance in Silene, and find no evidence for the operation of speciation via reinforcement.

MacClade: Analysis of phylogeny and character evolution

TL;DR: MacClade is a computer program that provides theory and tools for the graphic and interactive analysis of molecular and morphological data, phylogeny, and character evolution, yet its ease of use allows beginning students to grasp phylogenetic principles in an interactive environment.

Cases in which Parsimony or Compatibility Methods will be Positively Misleading

TL;DR: Parsimony or minimum evolution methods were first introduced into phylogenetic inference by Camin and Sokal (1965), and a number of other parsimony methods have since appeared in the systematic literature and found widespread use in studies of molecular evolution.

The limits of amino acid sequence data in angiosperm phylogenetic reconstruction.

TL;DR: Cladistic analysis of amino acid sequence data, including evaluation of all equally or almost equally parsimonious cladograms, shows that much homoplasy (parallelisms and reversals) is present and that few or no well supported monophyletic groups of families can be demonstrated.

Relationships between gene trees and species trees.

TL;DR: It is well known that a phylogenetic tree (gene tree) constructed from DNA sequences for a genetic locus does not necessarily agree with the tree that represents the actual evolutionary pathway of the species involved (species tree).
