Phylogenomic loci define the generic boundaries of Gochnatieae and improve resolution at the species level in Moquiniastrum (Compositae)

Understanding the evolution of the tribe Gochnatieae (Compositae) has been the subject of considerable effort in the past decade. This is due to the key position of this tribe in the phylogeny of the sunflower family and the corresponding implications for biogeographic and morphological evolution of Compositae. Previous studies have confirmed the monophyly of this tribe as well as most of the genera that belong to it. However, phylogenetic resolution of Gochnatieae at both the genus- and species-level has remained poor. A subset of new phylogenomic loci used in this study has proven effective and has improved phylogenetic resolution in this group. The results of this work demonstrate Gochnatieae is a well-supported clade comprised of nine genera (Anastraphia, Cnicothamnus, Cyclolepis, Gochnatia, Moquiniastrum, Nahuatlea,  Pentaphorus, Richterago, Tehuasca). One recently described genus, Vickia, was not included in this study; but its placement in Gochnatieae as a tenth genus in the trib..., High-throughput sequencing libraries were generated using microfluidic PCR-based target enrichment and sequenced on an Illumina MiSeq. Sequences were demultiplexed, cleaned, assembled, and then aligned per locus. Geographic areas were selected based on occurrence data gathered from herbarium records for all taxa included in this study. Ancestral character state matrices were constructed from herbarium collections and taxonomic knowledge by the taxonomic specialists who are authors of this manuscript., , # Data from: Phylogenomic loci define the generic boundaries of Gochnatieae and improve resolution at the species level in Moquiniastrum (Compositae)
