The phylogenic relationships, gene structures, and conserved motifs of maize ACBP family genes. The phylogenetic tree was constructed using MEGA 7.1 software by the Neighbor-Joining method with 1000 bootstrap replicates. The different ACBP classes were marked with dots of different colors: green, class I; yellow, class II; blue, class III; red, class IV. The yellow boxes and grey lines represent exons and introns, respectively. The wide boxes of different colors represent different conserved motifs. The scales were referred to the lengths of exons, introns and motifs, respectively
