AbstractThe Caryophyllales includes 40 families and 12,500 species, representing a large and diverse Glade of angios-perms. Collectively, members of the Glade grow on all continents and in all terrestrial biomes and often occupy extreme habitats (e.g., xeric, salty). The order is characterized by many taxa with unusual adaptations including carnivory, halophytism, and multiple origins of C-4 photosynthesis. However, deep phylogenetic relationships within the order have long been problematic due to putative rapid divergence. To resolve the deep-level relationships of Caryophyllales, we performed phylogenomic analyses of all 40 families of Caryophyllales. We time-calibrated the molecular phylogeny of this Glade, and evaluated putative correlations among plastid structural changes and rates of molecular substitution. We recovered a well-resolved and well-supported phylogeny of the Caryophyllales that was largely congruent with previous estimates of this order. Our results provide improved support for the phylogenetic position of several key families within this Glade. The crown age of Caryophyllales was estimated at ca. 114.4 million years ago (Ma), with periods of rapid divergence in the mid-Cretaceous. A strong, positive correlation between nucleotide substitution rate and plastid structural changes was detected. Our study highlights the importance of broad taxon sampling in phylogenomic inference and provides a firm basis for future investigations of molecular, morphological, and ecophysiological evolution in Caryophyllales.
