Phylogenetic tree of the sucrose transporter (SUT) family. (A) Clade overview, (B) SUT1–SUT4 clade, (C) SUT2 clade. The tree was obtained by aligning all protein sequences using ClustalW and then build using the software Molecular Evolutionary Genetics Analysis (MEGA v5, Tamura et al., 2011). The bootstrap consensus tree is inferred from 1000 replicates. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test is shown next to the branches. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analysis involved 99 amino acid sequences and a total of 401 positions.
