The evolutionary history, ecological, morphological and genetic diversity and abundant resources and knowledge of Brassicaceae make it an excellent model family for evolutionary studies. Recent phylogenetic analyses of the family revealed three major lineages (I, II, and III), but relationships among and within these lineages remain largely unclear. Here, we present a highly supported phylogeny with six major clades using nuclear markers from newly sequenced transcriptomes of 32 Brassicaceae species and datasets from additional taxa for a total of 81 species spanning 32 of 49 tribes. Clade A consisting of Lineage I and Macropodium nivale is sister to a combined clade of Clade B (with Lineage II and others) and a new Clade C. The ABC clade is sister to Clade D with species weakly associated with Lineage II and Clade E (Lineage III) is sister to ABCD. Clade F (the tribe Aethionemeae) is sister to the remainder of the family. Molecular clock estimation reveals an early radiation of major clades near the boundary of Eocene and Oligocene and subsequent nested radiations of several tribes of previously polytomous Expanded Lineage II. Reconstruction of ancestral morphological states during the Brassicaceae evolutionary history indicates prevalent parallel (convergent) evolution of several traits over deep time across this family. These results form a foundation for future evolutionary analyses of structures and functions across Brassicaceae.} }
