Fig. 3: Legume karyotype evolution.

The 16 ancestral legume chromosomes (called Lu, denoted by capital letters A–Q), were reconstructed by using corresponding common bean genes and compared with extant legume genomes. By using dot plots between Lu and each legume genome, and between close legume relatives, we reconstruct the origin of peanut chromosomes, including A. duranensis and A. ipaensis.
