Fig. 2

Phylogenetic relationships, gene structure and motifs of HAK genes from M. truncatula and M. sativa (A, B, and C) using TBtools. The groups and their color in phylogenetic tree were the same as in Fig. 1. Black boxes indicate 5′- and 3′- untranslated regions; boxes with the same color as in panel A indicate exons; black lines indicate introns. The motifs were indicated in different colored boxes with different numbers and the sequence information for each motif was provided in Additional Fig. S1
