Figure 1.

Phylogenetic analysis, gene structure, and motif analysis of the MdGSTs. (A) The phylogenetic analysis of GST family genes of Arabidopsis, apple, and tomato. The tree was constructed via the maximum likelihood method with 1000 bootstrap replications. A neighbor-joining tree was generated by MEGA X software, and the tree was annotated using Interactive Tree Of Life (iTOL). The solid line represents the real branch length, and the dotted lines were added later for better visualization. (B) Exon-intron structure analysis of MdGST genes. The exons and introns are represented by yellow boxes and black lines, respectively. (C) Conserved domains of the MdGSTs, represented by colored blocks.
