Amino acid sequence alignment of ScWRKY3 and WRKYs from other plant species by DNAMAN (version 6.0.3.99, Lynnon Biosoft) software. The amino acid sequences of Miscanthus lutarioriparius MlWRKY12 (AGQ46321.1), Zea mays ZmWRKY51 (XP_020393361.1), Sorghum bicolor SbWRKY57 (XP_002452824.2), Setaria italica SiWRKY12 (XP_004953301.1), and Oryza sativa OsWRKY12 (XP_015624962.1) are from GenBank. The black, pink, blue, and white colors indicate the homology level of conservation of the amino acid residues in the alignment at 100, ≥75, ≥50, and <50%, respectively. The sequences of the WRKY motif (WRKYGQK) and the C2H2 domain (CX4CX23HXH) are highlighted by the red rectangle.
