Figure 7

Phylogenetic analysis of the β -tubulin gene subfamily. Unrooted neighbor-joining tree generated using the aligned nucleotide sequences of 8 Arabidopsis (green dots), 20 poplar (blue dots), and 9 apple (red dots) members of the β-tubulin gene subfamily. Bootstrap values higher than 75 are indicated under each branch. Ks distances between apple paralogs are indicated on the left of each node. Apple gene duplications tentatively assigned to the Pyrinae polyploidization (black squares) or small-scale events (white squares) are marked.
