Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae.
TLDR
The results of molecular phylogenetic studies of members of tribes Helenieae, Heliantheae, and Eupatorieae (Asteraceae) and General systematics and proposed taxonomic changes in current classification are presented. Expand
Generic Delimitation and Phylogeny of the Subtribe Centaureinae (Asteraceae): A Combined Nuclear and Chloroplast DNA Analysis
Abstract Taxonomic complexity has hindered the partitioning of the artificial genus Centaurea, even though it has long been recognized as a polyphyletic assemblage. On the basis of morphology, pollenExpand
THE CARDUEAE (COMPOSITAE) REVISITED: INSIGHTS FROM ITS, trnL-trnF, AND matK NUCLEAR AND CHLOROPLAST DNA ANALYSIS1, 2
Abstract The new outline of relationships in basal branches of the family Compositae Giseke confirms that the sister group to the tribe Cardueae Cass. are not Mutisieae Cass., but rather a group ofExpand
Centaurea revisited: A molecular survey of the Jacea group.
TLDR
The results show that the sectional classification in current use needs major revision, with many old sections being merged into larger ones and most recent groups in the eastern Mediterranean clade are not resolved and reticulation in the western Mediterranean group of sections makes phylogenetic relationships within these two groups somewhat obscure. Expand
Natural Delineation, Molecular Phylogeny and Floral Evolution in Campanula
TLDR
Both Bayesian and Parsimony analyses indicate that the main morphological characters used in classifications, such as flower shape and capsule dehiscence, have arisen in parallel. Expand
Taxonomic problems in Carthamus (Asteraceae): RAPD markers and sectional classification
TLDR
The results confirm that methodological problems posed by RAPD markers can be avoided by careful laboratory procedures and appropriate data analyses and suggest that this kind of marker is useful at low taxonomic levels and is, furthermore, complementary to DNA sequence analysis. Expand
Reconstructing the history of Campanulaceae with a Bayesian approach to molecular dating and dispersal-vicariance analyses.
TLDR
Biogeographic and dating analyses suggest that Western Asia and the Eastern Mediterranean have played a major role as centers of migration and diversification within the Campanula alliance, probably in relation to the intense orogenic activity that took place in this region during the Late Neogene. Expand
Systematics and evolution of the needle grasses (Poaceae: Pooideae: Stipeae) based on analysis of multiple chloroplast loci, ITS, and lemma micromorphology
TLDR
The phylogenetic hypothesis supports the recognition of the following genera and groups and monophyly of Phaenospermateae including Duthieinae is demonstrated, and its inclusion within or treatment as sister to Stipeae is rejected. Expand
Generic delimitation and phylogeny of theCarduncellus-Carthamus complex (Asteraceae) based on ITS sequences
TLDR
Most of the unusual morphological features in the Mediterranean complex Carduncellus-Carthamus complex appear to be reversals to ancestral character states and should be classified into four genera. Expand
The Genus Artemisia and its Allies: Phylogeny of the Subtribe Artemisiinae (Asteraceae, Anthemideae) Based on Nucleotide Sequences of Nuclear Ribosomal DNA Internal Transcribed Spacers (ITS)
TLDR
The results definitely support the monophyly of the genus Artemisia in its broadest sense and suggest that some infrageneric groups must be redefined, especially the subgenus Artemisia. Expand
