Lupins are legumes that are diverse and geographically widespread mainly around Mediterranean basin and both Americas. European lupins also exhibit great variability in chromosome number (2n=32-52), the basic chromosome number (x=5-9, 13) and genome size (0.97 pg/2C to 2.44 pg/2C). Comparative BAC-FISH analyses highlighted chromosomes variations and its multiple rearrangements. We proposed along with phylogeny data, the model of lupin chromosome evolution through three round of whole genome duplication, with assistance to aneuploidy. We assume the basic chromosome number as x=6, that is considered also for American lupins. The outstanding complex genome evolution makes lupin fascinating model for evolutionary studies. Polyploidy may provide an privilege in domestication, thus development of fundamental (cyto)genetic is a crucial to utilisate lupins in modern plant improvement. View this paper.
