Resolution of deep nodes yields an improved backbone phylogeny and a new basal lineage to study early evolution of Asteraceae
Abstract
Resolution of basal Asteraceae clades yields better backbone for supertree construction and placement of fossil calibrations. A monotypic taxon is found sister to >99% of Asteraceae and named subfamily Famatinanthoideae. Earliest African divergences coincide with floral, inflorescence and habit shifts to states that characterize most Asteraceae. Insect pollination syndrome confirmed ancestral in Asteraceae with subsequent parallel evolution of bird pollination.
