Amino acid alignment, conserved residues and structure of the four soybean WRKY genes. (A) Amino acid alignment and identification of conserved residues. The conserved WRKY amino acid signature and the amino acid forming the zinc-finger motif are highlighted in black and gray, respectively. Other conserved amino acids are boxed in black. Multiple sequence alignment was performed using CLUSTAL W 2.1. Highly conserved residues are indicated by (*), strongly similar by (:) and weakly similar by (.). (B) Structure of WRKY-encoding genes. Glyma08gg23380.1, Glyma08gg23380.2, Glyma08gg23380.3 and Glyma08gg23380.4 are alternative transcripts of Glyma08gg23380. The gray boxes represent exons and the black boxes indicate the exons that contain the WRKY domain. The dotted lines represent introns.
