Egan, Ashley N. [1].

A comprehensive generic-level phylogeny of Millettioid/Phaseoloid legumes (Fabaceae) places many genera never before sampled into evolutionary context.

The phaseoloid and millettiod legume clades include the classically circumscribed Phaseoleae and Millettieae tribes, comprising ~190 genera and over 3200 species, including many important economic plants, such as soybean (Glycine max) and common bean (Phaseolus vulgaris), as well as many rare genera that have never before been included in a phylogenetic context. The two groups are polyphyletic with each other. Here we present a three-gene, comprehensive, generic-level phylogeny that samples over 90% of the genera and places many genera into evolutionary context that were never included in a molecular phylogeny previously. We discuss the ramifications of this new knowledge on supra-generic classifications and present suggestions for a new tribal and subtribal classification.
