The classification of the Compositae: A tribute to Vicki Ann Funk (1947–2019)

The classification of the family Compositae (Asteraceae) has been much improved in the last decades by the application of molecular methods culminating in the recompilation published in 2009, Systematics, evolution, and biogeography of Compositae. Additional evidence of relationships has come from the use of high-throughput sequencing methods. Our late colleague Vicki Ann Funk (1947–2019) was a pioneer in this line of research. Together with her team, she contributed to the achievement of a mature classification of the family, which she left outlined. In this paper, we contribute this classification including all of the recent advances at the subtribal level and review in depth all contributions to Compositae classification made since the 2009 compilation.Abstract Introduction Material and methods Classification of Compositae Discussion and conclusions New infrafamilial taxa Author contribution

The Compositae Tree of Life in the age of phylogenomics

Comprising more than 25000 species, the Sunflower Family (Compositae or Asteraceae) is the largest family of flowering plants. Many of its lineages have experienced recent and rapid radiations, and the family has a deep and widespread history of large-scale gene duplications and polyploidy. Many of the most important evolutionary questions about the family's diversity remain unanswered due to poor resolution and lack of support for major nodes of the phylogeny. Our group has employed a phylogenomics approach using Hyb-Seq that includes sequencing approximate to 1000 low-copy number nuclear markers, plus partial plastomes for large numbers of species. Here we discuss our progress to date and present two phylogenies comprising nine subfamilies and 25 tribes using concatenated and coalescence-based analyses. We discuss future plans for incorporating high-quality reference genomes and transcriptomes to advance systematic and evolutionary studies in the Compositae. While we have made great strides toward developing tools for employing phylogenomics and resolving relationships within Compositae, much work remains. Recently formed global partnerships will work to solve the unanswered evolutionary questions for this megafamily
