a Phylogenetic relation between the identified GmNHXs and their genetic structure (CDS, intron/exon regions) constructed using the gene structure display server (GSDS 2.0, http://gsds.cbi.pku.edu.cn/index.php). The phylogenetic tree is divided in two groups representing two different branches. CDS: coding sequence, kb: kilobases; b Identification and distribution of the conserved motifs in GmNHXs. The identification, distribution and positioning of ten different motifs was obtained using online MEME server (http://meme-suite.org/). The diagram was constructed using TBtools software; c Distribution of the conserved Na⁺/H⁺ exchanger domain (Na_H_Exchanger) in GmNHX proteins. The domain analysis was done using the HMMER and the diagram was constructed using TBtools software
