Phylogenetic relationship between HaPTRs and related proteins. The analysis was performed using the aligned protein sequences of the Arabidopsis NRT1/PTR gene family, including proteins from other plant species for proteins of subfamily II (PTR1-like proteins, Rentsch et al., 2007; Tsay et al., 2007; AtPTR3, Karim et al., 2007; VfPTR1, Miranda et al., 2003; NaNTR1, Schulze et al., 1999; PdPTR2, Campalans et al., 2001; LeNTR1, AF016713; HvPTR1, West et al., 1998). Maximum parsimony analysis was performed using PAUP 4.0b10 with all characters unweighted and gaps scored as missing characters (Swofford, 2003). The complete alignment was based on 1409 amino acids; 633 characters were parsimony informative. The yeast peptide transporter ScPTR2 was used as the outgroup.
