Fig. 2. Phylogenetic relationships, gene structures and conserved motifs of Sm-NAC genes. a, phylogenetic tree of 84 Sm-NAC genes; b, exon—intron structures of Sm-NAC genes, blue boxes denote untranslated 5′-and 3′- regions; yellow boxes denote exons; black lines denote introns; numbers denote the phase of the corresponding intron; and c, Sm-NAC protein motifs. Each motif is indicated by a colored box numbered at the bottom. (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)
