Figure 2.
The phylogenetic tree of cation/H+ exchangers from Glycine soja and Arabidopsis thaliana. The phylogenetic tree was produced by MEGA 6.0 software based on the full-length amino acid sequence. The neighbor-joining method was used with 1000 bootstrap replications. CHXs were divided into five groups (Group I, II, III, IV and V) and separated by different colors. Genes from different species are marked with different bullet point colors.
