The phylogenetic relationships of Silphium and subtribe Engelmanniinae were examined using DNA sequence data. The internal transcribed spacer (ITS) region and the external transcribed spacer (ETS) region were sequenced for 39 specimens representing the six genera of subtribe Engelmanniinae (Berlandiera, Chrysogonum, Dugesia, Engelmannia, Lindheimera, and Silphium), plus five additional genera identified as closely related to the Engelmanniinae by chloroplast DNA restriction site analysis, and… Expand
Phylogeny of Tragopogon L. (Asteraceae) Based on Internal and External Transcribed Spacer Sequence Data
TLDR
ITS and ETS sequence data provide strong support for the monophyly of Tragopogon under parsimony optimality criteria and indicate possible relationships for 17 species that had not been previously placed in any section. Expand
A revised classification of subtribe Helianthinae (Asteraceae: Heliantheae) II. Derived lineages
TLDR
A revised generic-level classification is presented that divides the approximately 350 species of the subtribe among 21 genera, andalyses of the two molecular datasets provided conflicting evidence on relationships among some groups, supporting the hypothesis that hybridization has played a significant role in the divergence of thesubribe.

The phylogeny of Gaura (Onagraceae) based on ITS, ETS, and trnL-F sequence data.
TLDR
Molecular data provide support for the hypothesis that G. sinuata and G. drummondii arose via interspecific hybridization followed by genome doubling; their influence on phylogenetic reconstruction is discussed. Expand
Ragweeds and relatives: Molecular phylogenetics of Ambrosiinae (Asteraceae).
TLDR
Subtribe Ambrosiinae is found monophyletic or nearly so in all analyses and relationships among its genera are examined, allowing consideration of relationships among species and subgeneric groups within Parthenium, Iva, and Ambrosia. Expand
Nuclear rDNA Evidence for Major Lineages of Helenioid Heliantheae (Compositae)
TLDR
Pappi of bristles or bristle-like subulate scales have arisen in various lineages of Heliantheae s.s.l. and in general have received too much weight in previous circumscriptions of suprageneric taxa, according to the phylogenetic data. Expand
Hybrid genera in Liatrinae (Asteraceae: Eupatorieae).
TLDR
Phylogenetic analyses of nuclear ITS/ETS and plastid DNA data indicated that Garberia is the basalmost diverging lineage, and that Hartwrightia is phylogenetically embedded in the subtribe Liatrinae, and showed that Carphephorus s.l. is not monophyletic, and even after removal of the two species of Trilisa, it is still paraphyletic to Liatris. Expand
Phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) Using Its, Ets, and trnK Sequence Data
TLDR
The analyses support the monophyly of the Balsamorhiza/Wyethia clade, a clade of perennial herbs with large taproots and chromosome base numbers of x  =  19 that form aClade in the molecular trees and share synapomorphic large basal leaves. Expand
Molecular phylogeny and evolution of floral characters of Artemisia and allies (Anthemideae, Asteraceae): evidence from nrDNA ETS and ITS sequences
TLDR
The Artemisia/Kaschgaria lineage probably originated from an ancestor with disciform capitula, central hermaphrodite florets and Artemisia pollen type, and character reconstruction reveals that discoid capitula and Anthemis pollen type are the ancestral condition in the subtribe. Expand
An ITS phylogeny of Balsamorhiza and Wyethia (Asteraceae: Heliantheae).
TLDR
The relationships among the species of Balsamorhiza and Wyethia (Asteraceae: Heliantheae) were examined using data from the internal transcribed spacer (ITS) region of the nuclear ribosomal DNA to show that the two groups together form a monophyletic group. Expand

Phylogenetic affinities among and within the coneflower genera (Asteraceae, Heliantheae), a chloroplast DNA analysis

Chloroplast DNA data support Robinson's subtribal disposition of the coneflower genera, including Echinacea and Rudbeckia, and two evolutionary lineages were supported. Expand
a molecular phylogeny of apiaceae subfamily Apioideae: evidence from nuclear ribosomal DNA internal transcribed spacer sequences
TLDR
IT sequences are useful for phylogenetic inference among closely related members of Apioideae but, owing to high rates of nucleotide substitution, are less useful in resolving relationships among the more ancestral nodes of the phylogeny. Expand
Phylogenetic utility of the external transcribed spacer (ETS) of 18S-26S rDNA: congruence of ETS and ITS trees of Calycadenia (Compositae).
TLDR
The 3' region of the external transcribed spacer of 18S-26S nuclear ribosomal DNA was sequenced in 19 representatives of Calycadenia/Osmadenia and two outgroup species to assess its utility for phylogeny reconstruction compared to rDNA internal transcribing spacer (ITS) data to conclude that the ETS holds great promise for augmenting ITS data for phylogenetic studies of young lineages.

TLDR
The nuclear small-subunit rDNA sequences (16S-like) evolve rela­ tively slowly and are useful for studying distantly related organisms, whereas the mitochondrial rRNA genes evolve more rapidly and can be useful at the ordinal or family level. Expand

TLDR
The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters. Expand
