Fig. 2From: A systematical genome-wide analysis and screening of WRKY transcription factor family engaged in abiotic stress response in sweetpotatoMultiple sequence alignment of WRKY domains extracted from IbWRKY proteins. Identity, similarity, and deletions among WRKY alignments are indicated by black, grey shades and hyphens, respectively. The amino acid residues in the WRKY domain and the zinc finger domain are identified by red dotsBack to article page
