Phylogenetic relationships and exon-intron structure of MATE genes. a A neighbor-joining (N-J) phylogenetic tree was constructed using the complete protein sequence alignments of 101 MATE genes identified using MUSCLE and MEGA6. Numbers at the nodes represent bootstrap support values (1000 replicates). The color of the subclades indicates the four gene subfamilies. b Exon-intron structures of the MATE genes. Boxes, exons; lines, introns. The lengths of boxes and lines are scaled according to gene length
