Trwe de recurso: Artículo publicado. Resumen A backbone phylogeny that fully resolves all subfamily and deeper nodes of Asteraceae was constructed using 14 chloroplast DNA loci. A monotypic subfamily Famatinanthoideae and tribe Famatinantheae are named what does the root of a phylogenetic tree represent as new. Relationships among the basal lineages of the family were resolved with strong support in the Bayesian analysis as Barnadesioideae Famatinanthoideae Mutisioideae Stifftioideae Wunderlichioideae-Asteroideae.

Ancestral state reconstruction of ten morphological characters at the root node of the Asteraceae 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. Herbaceous habit, echinate pollen surface, pubescent styles, and cymose capitulescences were reconstructed for backbone nodes of the phylogeny corresponding to clades that evolved shortly after Asteraceae dispersed out of South America.

No support was found for discoid capitula, multiseriate involucres or bird pollination as the ancestral character condition for any node. Mutisiapollis telleriae fossil should be associated to a repdesent derived node than previously suggested what does the root of a phylogenetic tree represent time calibrating phylogenies of Asteraceae.
