Gene structure and conserved motifs of SiAATs in each subfamily. Different subfamilies of foxtail millet AAT family are shown with various color backgrounds. The gene structure was referred from the gene model file of foxtail millet reference genome. The exons, UTR regions and introns are displayed by green boxes, yellow boxes and the block lines, respectively. The detail motif sequences are as listed in Additional file 2: Fig. S2
