Maximum likelihood phylogeny of the NHX family. Nodes marked with black filled triangles represent nodes with bootstrap support > 75% (see Additional file 1: Figure S1 for more details). The root was placed using the yeast NHX protein as outgroup. The two main clades and Arabidopsis, rice, gymnosperm (Gymn.), spikemoss (Spike.), moss, alga, and yeast sequences are highlighted. (See Additional file 2: Table S1 for sequences’ codes).
