Lessons from Plectocephalus (Compositae, Cardueae-Centaureinae): ITS disorientation in annuals and Beringian dispersal as revealed by molecular analyses.
BACKGROUND AND AIMS The geographic distribution of the genus Plectocephalus comprises a single species in Ethiopia, two in North America and possibly four more in South America, in a striking disjunction that is exceptional for genera of the tribe Cardueae. The enormity of this disjunction cast doubts on the precise taxonomic delineation of the genus, which is not unanimously recognized as a na...
متن کاملReconstructing the evolution and biogeographic history of tribe Cardueae (Compositae).
UNLABELLED PREMISE OF THE STUDY Tribe Cardueae (thistles) forms one of the largest tribes in the family Compositae (2400 species), with representatives in almost every continent. The greatest species richness of Cardueae occurs in the Mediterranean region where it forms an important element of its flora. New fossil evidence and a nearly resolved phylogeny of Cardueae are used here to reconst...
متن کاملEvolution of Specialization of Cassida rubiginosa on Cirsium arvense (Compositae, Cardueae)
The majority of herbivorous insects are specialized feeders restricted to a plant family, genus, or species. The evolution of specialized insect-plant interactions is generally considered to be a result of trade-offs in fitness between possible hosts. Through the course of natural selection, host plants that maximize insect fitness should result in optimal, specialized, insect-plant association...

متن کاملMolecular Systematics of Genus Atractylodes (Compositae, Cardueae): Evidence from Internal Transcribed Spacer (ITS) and trnL-F Sequences
To determine the evolutionary relationships among all members of the genus Atractylodes (Compositae, Cardueae), we conducted molecular phylogenetic analyses of one nuclear DNA (nrDNA) region (internal transcribed spacer, ITS) and one chloroplast DNA (cpDNA) region (intergenic spacer region of trnL-F). In ITS and ITS + trnL-F trees, all members of Atractylodes form a monophyletic clade. Atractyl...
