Phylogenetic relationships of TaSUT2 with other plant SUTs. Phylogenetic tree was generated based on amino acid sequence similarity of TaSUT2A, TaSUT2B and TaSUT2D with that of SUTs identified from representative monocotyledonous and dicotyledonous species using MEGA program [33]. The evolutionary history was inferred using the Neighbor-Joining method. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) is shown next to the branches. The evolutionary distances were computed using the Poisson correction method and are in the units of the number of amino acid substitutions per site. The analysis involved amino acid sequences of 40 SUTs: Apium graveolens, AgSUT2, AF167415; Triticum aestivum, TaSUT1A, AAM13408; TaSUT1B, AAM13409.1; TaSUT1D, AAM13410.1; Hordeum vulgare, HvSUT1, CAJ20123.1; HvSUT2, CAB75881.1; Oryza sativa, OsSUT1, BAI83443.1; OsSUT2, BAC67163.1; OsSUT3, BAB68368.1; OsSUT4, BAC67164.1; OsSUT5, BAC67165.1; Zea mays, ZmSUT1, NP_001104840; ZmSUT2, AAT51689; ZmSUT3, ACF86653.1; ZmSUT4, AATS91375.1; ZmSUT5, ACF85284.1; ZmSUT6, ACF86653.1; Solanum tuberosum, StSUT1, CAA48915.1; StSUT2, AAP43631.1; StSUT4, AAG25923.2; Arabidopsis thaliana, AtSUC1, CAA53147.1; AtSUC2, CAA53150.1; AtSUT2, AAC32907.1; AtSUT4, AAG09191.1; AtSUT5, BAB11624.1; AtSUT8, AAC69375.1; Lycopersicon esculentum, LeSUT1, CAA57726.1; LeSUT2, AAG12987.1; LeSUT4, AAG09270.1; Vitis vinifera, VvSUC11, AAF08329.1; VvSUC12, AAF08330.1; VvSUC27, AAF08331.1; Daucus carota, DcSUT1A, CAA76367.1; Sorghum bicolor, SbSUT1, ACY69230.1; SbSUT2, XX_00243677.1; SbSUT3, XP_002467275.1; SbSUT4, EES06059.1; SbSUT5, XP_002454058.1; Brassica oleracea, BoSUC2, AAL58072.1; Lotus japonica, LjSUT4, AJ538041.
