Phylogenetic relationship, motif and gene structure of wheat Aux/IAA genes. (A) The phylogenetic tree of TaIAAs constructed from a complete alignment of 84 wheat Aux/IAA genes using MEGA 6.0 by the neighbor-joining method with 1000 bootstrap replicates. Bootstrap scores are indicated on the nodes and the 34 members of TaIAA, most of which contain duplicated genes, are indicated by blue or pink block. (B) The conserved motifs of TaIAAs. Motifs were identified by MEME software using the deduced amino-acid sequences of the TaIAAs. The relative position of each identified motif in all TaIAA proteins is shown as 1, 2, 3, and 4, which represented the four conserved domains of IAA. (C) Exon/intron structures of TaIAA genes. Exons are represented by black boxes and introns by black lines. The sizes of exons and introns can be estimated using the scale below.
