Dichotomy in the NRT Gene Families of Dicots and Grass Species
Figure 7
Phylogenetic relationship of the NRT3.2SF2/3 family.
Unrooted Neighbour-joining tree of NRT3.2SF2/3 family in Arabidopsis (black), poplar (blue) and 4 grass species: rice (orange), sorghum (green), maize (red) and Brachypodium (purple). Bootstrap values from 1,000 replicates were used to estimate the confidence limits of the nodes. The scale bar represents a 0.04 estimated amino acid substitution per residue.
