Phylogenetic tree, gene structure and motif distribution analysis of 54 IbDEAH-box members. A Phylogenetic tree of DEAH-box members in sweetpotato and the consistent parameters shown in Fig. 2(A). The different groups are marked with different colors. B The exon–intron structure analysis of 54 IbDEAH-box genes and the consistent parameters shown in Fig. 2(B). C Motif distribution of 54 IbDEAH-box proteins. The different colored boxes represent 15 motifs, and the box lengths represent motif lengths
