Since the tetraploidization of the Arabidopsis thaliana ancestor 30-35 million years ago (Mya), a wave of chromosomal rearrangements have modified its genome architecture. The dynamics of this process is unknown, as it has so far been impossible to date individual rearrangement events. In this paper, we present evidence demonstrating that the majority of rearrangements occurred before the Arabidopsis-Brassica split 20-24 Mya, and that the segmental architecture of the A. thaliana genome is… CONTINUE READING
