Phylogenomics of Perityleae (Compositae) provides new insights into morphological and chromosomal evolution of the rock daisies
<p>Rock daisies (Perityleae; Compositae) are a diverse clade of seven genera and ca. 84 minimum-rank taxa that mostly occur as narrow endemics on sheer rock-cliffs throughout the southwest U.S. and northern Mexico. Taxonomy of Perityleae has traditionally been based on morphology and cytogenetics. To test taxonomic hypotheses and utility of characters emphasized in past treatments, we present the first densely sampled molecular phylogenies of Perityleae and reconstruct trait and chromosome evolution. We inferred phylogenetic trees from whole chloroplast genomes, nuclear ribosomal cistrons, and hundreds of low-copy nuclear genes using genome skimming and target-capture. Discordance between sources of molecular data suggests a underappreciated history of hybridization in Perityleae. Phylogenies support the monophyly of subtribe Peritylinae, a distinctive group possessing a four-lobed disc corolla; however, all of the phylogenetic trees generated in this study reject the monophyly of the most species-rich genus, Perityle as well as its sections Perityle sect. Perityle, Perityle sect. Laphamia, and Perityle sect. Pappothrix. Using reversible jump MCMC, our results suggest that morphological characters traditionally used to classify members of Perityleae have evolved multiple times within the group. A base chromosome number of x=18 gave rise to lower base numbers in subtribe Peritylinae (x=12, 13, 16, 17, and 19) by descending dysploidization. Most taxa constitute a monophyletic lineage with a base chromosome number of x=17, with many polyploidization events. These results demonstrate the advantages and obstacles to next-generation sequencing approaches in synantherology while laying the foundation for taxonomic revision and comparative study of the evolutionary ecology of Perityleae</p>
Data from: A target enrichment method for gathering phylogenetic information from hundreds of loci: an example from the Compositae
Premise of the study: The Compositae (Asteraceae) are a large and diverse family of plants, and the most comprehensive phylogeny to date is a meta-tree based on 10 chloroplast loci that has several major unresolved nodes. We describe the development of an approach that enables the rapid sequencing of large numbers of orthologous nuclear loci to facilitate efficient phylogenomic analyses. Methods and Results: We designed a set of sequence capture probes that target conserved orthologous sequences in the Compositae. We also developed a bioinformatic and phylogenetic workflow for processing and analyzing the resulting data. Application of our approach to 15 species from across the Compositae resulted in the production of phylogenetically informative sequence data from 763 loci and the successful reconstruction of known phylogenetic relationships across the family. Conclusions: These methods should be of great use to members of the broader Compositae community, and the general approach should also be of use to researchers studying other families.
