Article
The 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 gene...
