Figure 3. Analysis of gene structures and conserved motifs of AsbHLH members. ( A ) The phylogenetic relationship of AsbHLHs. ( B ) Exon–intron structure of AsbHLH s. The green boxes, yellow boxes and black lines represent untranslated 5 ′ - and 3 ′ -regions, exons and introns, respectively. ( C ) Motif analysis of the AsbHLH proteins. Twenty predicted motifs are displayed in different colored boxes. For the information of motif details refer to Supplementary Table S2. The size of the structures and motifs can be estimated by the scale at
