Everywhere but Antarctica: using a supertree to understand the diversity and distribution of the Compositae.
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.
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, pollen…
Reconstructing the evolution and biogeographic history of tribe Cardueae (Compositae).
Most diversification events within Cardueae are related to the continuous cycles of area connection and division between the Anatolian microplate and the western Mediterranean Basin during the Oligocene-Miocene and with the uplift of the Himalayan range from the Miocene onward.
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 of…
Phylogenetic relationships in tribe Cardueae (Asteraceae) based on ITS sequences
DNA sequences of the internal transcribed spacers of the nuclear ribosomal RNA genes of 35 taxa are analyzed to reconstruct the phylogeny of Cardueae and assess the positions of Echinopsidinae and Carlininae, the circumscription of the Carduinae-Centaureinae complex, and the limits of Centaurea and related genera.

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.
Reconstructing the history of Campanulaceae with a Bayesian approach to molecular dating and dispersal-vicariance analyses.

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.
Taxonomic problems in Carthamus (Asteraceae): RAPD markers and sectional classification
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.
