Phylogenetic relationship between Arabidopsis spp. and Capsella spp. The phylogenetic relationship between A. thaliana, A. lyrata, and Capsella spp. is illustrated in this simple cartoon (modified from Koch et al. 1999). Extensive colinearity of mapping data suggests (A) conservation of genome arrangement since the ancestor of the tribe Sisymbrieae (n = 8) until these modern-day taxa with haploid complement of n = 8, and (B) the occurrence of most major genome rearrangement events in the last 5 Myr of A. thaliana's evolutionary history.
