This species has been preferred as a model organism for legume biology because it has a small diploid (2n = 16) genome (500-550 Mbp total and200-250 Mbp to be sequenced in gene-rich euchromatic regions), is self-fertile, has a rapid generation time and prolific seed production, and is amenable to genetictransformation (Erayman et al.
