Phylogenetic relationship between the NHXs of G. max and the reference plants (Arabidopsis thaliana, Brassica rapa, Brassica oleracea, Brassica napus, Cucumus sativus, Lupinus angustifolius, Medicago trancatula, Phaseolus, Solanum tuberosum, Solanum lycopersicum, Trifolium pratense, Vigna radiata, Vigna angularis and Vitis vinifera) (Table S8). The peptide sequences of GmNHXs were aligned with reference peptides using Clustal Omega tools and phylogenetic tree was constructed by MEGA-X using the neighbor-joining (NJ) method, with 1000 bootstrap replicates
