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. Expand

The largest family of flowering plants Asteraceae (Compositae) is found to contain 12 major lineages rather than five as previously suggested, contradict earlier hypotheses that early divergences in the family took place on and spread from the Guayana Highlands and raise new hypotheses about how Asteraceae dispersed out of the continent of their origin.

Molecular evidence for multiple origins of woodiness and a new world biogeographic connection of the Macaronesian island endemic Pericallis (Asteraceae: senecioneae).
A phylogeny based on sequences of the internal-transcribed spacer region of nuclear ribosomal DNA is used to trace the evolution of woodiness in Pericallis, a genus endemic to the Macaronesian archipelagos of the Azores, Madeira, and Canaries, showing that woodiness originated independently at least twice in these islands.

Obeticholic acid for the treatment of non-alcoholic steatohepatitis: interim analysis from a multicentre, randomised, placebo-controlled phase 3 trial
Results from a planned interim analysis of an ongoing, phase 3 study of obeticholic acid for NASH show clinically significant histological improvement that is reasonably likely to predict clinical benefit. Expand
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. Expand
Macroevolutionary dynamics in the early diversification of Asteraceae.
Diversification rates increased gradually from the origin of Asteraceae approximately 69.5Ma in the late Cretaceous through the Early Eocene Climatic Optimum at least, and significant rate shifts were not strongly correlated with intercontinental dispersals or polyploidization. Expand
Toward a phylogenetic subfamilial classification for the Compositae (Asteraceae)
The results of molecular studies based on comparative DNA sequence data of chloroplast genes provide new insights into the evolution and radiation of the flowering plant family Compositae (Asteraceae) and support the creation of new groups to maintain a classification that reflects evolutionary history. Expand
Resolution of deep nodes yields an improved backbone phylogeny and a new basal lineage to study early evolution of Asteraceae.
A backbone phylogeny that fully resolves all subfamily and deeper nodes of Asteraceae was constructed using 14 chloroplast DNA loci and showed that the ancestral sunflower would have had a woody habit, alternate leaves, solitary capitulescences, epaleate receptacles, smooth styles, smooth to microechinate pollen surface sculpturing, white to yellow corollas, and insect-mediated pollination.

Phylogenetic analysis of Silphium and subtribe Engelmanniinae (Asteraceae: Heliantheae) based on ITS and ETS sequence data.
It is suggested that the cypsela complex, which is present in Berlandiera, Chrysogonum, Engelmannia, and Lindheimera, arose only once and was subsequently lost in Silphium, and supported the expansion of subtribe Engelmanniinae to include Balsamorhiza, Borrichia, Rojasianthe, Vigethia and Wyethia.

A phylogenetic analysis of Doronicum (Asteraceae, Senecioneae) based on morphological, nuclear ribosomal (ITS), and chloroplast (trnL-F) evidence.
It is argued that the morphological data set contains poor phylogenetic signal and advocate simultaneous analysis of the three data sets (total evidence approach) so that morphological characters are tested for homology by congruence with molecular data. Expand
