show Abstracthide AbstractThe inverted repeat-lacking clade (IRLC) is one of the most derived clades within the subfamily Papilionoideae of the legume family, and includes various economically important plants, e.g., chickpeas, peas, liquorice, and the largest genus of angiosperms, Astragalus. Tribe Wisterieae is one of the earliest diverged groups of the IRLC, and its generic delimitation and spatiotemporal diversification need further clarifications. Based on the genome skimming data, we herein reconstruct the inter-tribal phylogenomic framework of the IRLC, and infer the inter-generic relationships and historical biogeography of Wisterieae.
