Proteasome 20S subunit family: low tandem, high segmental The phylogeny on the left shows segmental duplications in the A. thaliana proteasome 20S subunit family, which lacks tandem duplications. The phylogeny on the right represents the same A. thaliana sequences but with M. truncatula and tomato EST sequences added to evaluate the degree to which these homologs are conserved. Relationships of clades represented in both phylogenies are in general agreement, with some differences due to instabilities of some deep nodes.
