Abstract The internal transcribed spacer (ITS) region of 18S–26S nuclear ribosomal DNA (rDNA) was sequenced in 65 taxa representing most coneflowers (i.e., species in Dracopis, Echinacea, Ratibida, and Rudbeckia) and other taxa representing 21 outgroup genera of tribe Heliantheae. Results of parsimony analysis of the rDNA dataset by itself and in combination with the cpDNA dataset uphold the hypothesis from an earlier cpDNA restriction site study that Echinacea is not closely related to the… 

Phylogeny of Stephanomeria and related genera (compositae-lactuceae) based on analysis of 18S-26S nuclear rDNA ITS and ETS sequences.

A phylogenetic analysis of DNA sequences from the internal transcribed spacer (ITS), the external transcribed spacer (ETS), and the 5.8S regions of 18S-26S nuclear rDNA from all diploid species of

Phylogenetic Relationships within the Tageteae (Asteraceae) Based on Nuclear Ribosomal ITS and Chloroplast ndhF Gene Sequences

The phylogeny suggests that the Tageteae probably originated in Mexico and that there have been at least three independent introductions into South America.

Nuclear rDNA Evidence for Major Lineages of Helenioid Heliantheae (Compositae)

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.

A Molecular Phylogenetic Study of Arnica (Asteraceae): Low Chloroplast DNA Variation and Problematic Subgeneric Classification

The analyses revealed that A. nevadensis is most closely related to A. dealbata and A. mallotopus forms a strongly supported clade with A. unalaschcensis, and earlier biogeographical hypotheses that suggested an arctic origin and southward spread of the genus are not supported.

Phylogeny of Hinterhubera Group and Related Genera (Hinterhuberinae: Astereae) Based on the nrDNA ITS and ETS Sequences

Analysis of phylogenetic relationships of six out of seven genera from the informal Hinterhubera group and nine other subtribes in tribe Astereae primarily with Southern Hemisphere distributions suggest a closer relationship among the taxa from similar geographic areas.

Phylogeny and ecological radiation of New World thistles (Cirsium, Cardueae – Compositae) based on ITS and ETS rDNA sequence data

Comparisons of this Californian lineage with other neoendemic angiosperm groups of the region show that the Californian Cirsium lineage exhibits unusually high ecological diversity for a group displaying such low levels of rDNA sequence divergence across taxa.

Molecular Phylogeny of Chrysothamnus and Related Genera (Asteraceae, Astereae) Based on Nuclear Ribosomal 3′ ETS and ITS Sequence Data

The results indicate that Chrysothamnus as traditionally perceived is polyphyletic, with species placed in four well-supported lineages, and some of the morphological features used to delimit these genera may be the product of convergence, thus diminishing their value for phylogenetic reconstruction.

Phylogenetic Relationships of Geum (Rosaceae) and Relatives Inferred from the nrITS and trnL-trnF Regions

Morphological characters, notably fruit characters, mapped onto the combined tree show patterns of widespread parallel evolution and reversals—or possibly the effects of reticulations.

The Phylogeny of Rosoideae (Rosaceae) Based on Sequences of the Internal Transcribed Spacers (ITS) of Nuclear Ribosomal DNA and the trnL/F Region of Chloroplast DNA

The phylogeny of Rosoideae was investigated using 44 species using new sequence data from the chloroplast trnL/F region as well as an increased sample of species, and the monophyly of both Potentilleae and Sanguisorbeae is well supported.

Preliminary phylogeny of Valerianaceae (Dipsacales) inferred from nuclear and chloroplast DNA sequence data.

Molecular phylogenetics of Calycadenia (Compositae) based on its sequences of nuclear ribosomal DNA: chromosomal and morphological evolution reexamined

A highly resolved, strict consensus tree from Wagner parsimony analysis of data suggests that the monotypic Osmadenia tenella is the sister-group to Calycadenia, and loss of chromosomal homology between CalyCadenia species, as reflected by meiotic chromosomal association in hybrids, is positively correlated with time since evolutionary divergence.

Phylogenetic Relationships in Sarraceniaceae Based on rbcL and ITS Sequences

P phylogenetic relationships in the family are investigated using sequences of the internal transcribed spacer regions of nuclear ribosomal DNA (ITS) and of the chloroplast gene rbcL to demonstrate that Sarracenia and Heliamphora form a monophyletic group that is the sister group of Darlingtonia.

A Phylogenetic Analysis of the Coneflower Genera (Asteraceae: Heliantheae)

Twenty-eight qualitative characters were chosen for cladistic analysis performed by the Branch and Bound algorithm in PAUP, which guarantees discovery of the most parsimonious tree, and the resulting cladogram presents the Rudbeckiinae as a monophyletic taxon with the genera of the Ecliptinae forming a group distinct from the coneflowers.

Chloroplast DNA data support Robinson's subtribal disposition of the coneflower genera, including Echinacea and Rudbeckia, and two evolutionary lineages were supported.

These studies, which have produced the largest molecular data set for any plant family, have allowed us to perform phylogenetic comparisons from the intraspecific to the interfamilial levels and to sequenced the gene encoding the large subunit of ribulose-l,5-bisphosphate carboxylase (rbcL).

Phylogenetic and Evolutionary Implications of Interspecific Chloroplast DNA Variation in Krigia (Asteraceae-Lactuceae)

Chloroplast DNA trees were consistent with the hypothesis that an ancient allopolyploid event between species with low chromosome base numbers, followed by subsequent aneuploid reduction, resulted in K. wrightii with n = 9 and suggest that x = 5 is the probable ancestral base number for the genus and that aneuPLoid reduction is the major mode of chromosome number change in Krigia and related genera.
