A TPS (consensus tree) B TPP (consensus tree) TPPE TPS7 TPPH TPPB TPPI TPS6 TPPC TPPJ TPS11 TPS5 TPPD TPS10 TPS9 TPS8 TPS1 TPS4 TPPA TPPF TPS2 TPS3 TPPG Supplemental Figure S3.Phylogenetic trees of Arabidopsis (TAIR9) and Brachypodiumdistachyon (Bd21_v1 gene models) protein sequences for the TPs and TPP gene families. Trees were created with the PHYML program (Guindon et al., 2005) implementing the WAG model of amino-acid substitution (Whelan and Goldman, 2001) from a full-length alignment (excluding gaps). Consensus trees from 100 bootstrap runs shown. A, trehalose phosphate synthase. B, trehalose phosphate phosphatase.
