Additional file 2:

Maximum Likelihood phylogenetic reconstructions of the NRT1 family by supergroup. For each tree, sequences were realigned and trimmed separately prior to phylogenetic reconstruction. Groups are defined and colored as in Figure  1. Bootstrap values from 1,000 replicates are given for branches up to those defining groups only. Supergroups C and D, supergroups F and G, and supergroups H and I were analyzed together, because they each form monophyletic clans with high bootstrap support (see Figure  1) but have bryophyte and lycophyte proteins with ambiguous relation to the two supergroups included.
