Fig. 1: Bioinformatic analysis of CmWRKY15-1.

a PCR amplification product of CmWRKY15-1. b Multiple amino acid sequence alignment between CmWRKY15-1 and several related WRKY proteins from the Asteraceae. The box indicates the WRKYGQK heptapeptide sequence; the triangle indicates the zinc-finger motif. c Secondary structure of the predicted CmWRKY15-1. Blue, alpha-helix; red, folding and extending chain; green, beta-turn; purple, random coil. d Three-dimensional structure of predicted CmWRKY15-1. e Phylogenetic analysis of CmWRKY15-1.
