Molecular phylogeny and spatio‐temporal diversification of the Millettioid/Phaseoloid clade (Fabaceae: Papilionoideae)
The Millettioid/Phaseoloid (or the Millettioid) clade is a major lineage of the subfamily Papilionoideae (Fabaceae) that is poorly understood in terms of its diversification and biogeographic history. To fill this gap, we generated a time‐calibrated phylogeny for 749 species representing c. 80% of the genera of this clade using nrDNA ITS, plastid matK, and plastome sequence (including 38 newly sequenced plastomes). Using this phylogenetic framework, we explored the clade's temporal diversification and reconstructed its ancestral areas and dispersal events. Our phylogenetic analyses support the monophyly of the Millettioid/Phaseoloid clade and four of its tribal lineages (Abreae, Desmodieae, Indigofereae, and Psoraleeae), while two tribal lineages sensu lato millettioids and phaseoloids are polyphyletic. The fossil‐calibrated dating analysis showed a nearly simultaneous divergence between the stem node (c. 62 Ma) and the crown node (c. 61 Ma) of the Millettioid/Phaseoloid clade in the Paleocene. The biogeographic analysis suggested that the clade originated in Africa and dispersed to Asia, Europe, Australia, and the Americas at different periods in the Cenozoic. We found evidence for shifts in diversification rates across the phylogeny of the Millettioid/Phaseoloid clade throughout the Cenozoic, with a rapid increase in net diversification rates since c. 10 Ma. Possible explanations for the present‐day species richness and distribution of the Millettioid/Phaseoloid clade include boreotropical migration, frequent intra‐ and intercontinental long‐distance dispersals throughout the Cenozoic, and elevated speciation rates following the Mid‐Miocene Climatic Optimum. Together, these results provide novel insights into major diversification patterns of the Millettioid/Phaseoloid clade, setting the stage for future evolutionary research on this important legume clade.
期刊介绍:
Journal of Systematics and Evolution (JSE, since 2008; formerly Acta Phytotaxonomica Sinica) is a plant-based international journal newly dedicated to the description and understanding of the biological diversity. It covers: description of new taxa, monographic revision, phylogenetics, molecular evolution and genome evolution, evolutionary developmental biology, evolutionary ecology, population biology, conservation biology, biogeography, paleobiology, evolutionary theories, and related subjects.
