PlumX metrics:

The WRKY proteins are one of the largest families of transcriptional regulators in plants. Their biosynthesis is

induced during certain stages of plant development and upon pathogen infection. A single WRKY transcription

factor may be involved in the regulation of several apparently disparate processes. Their hallmark is strong

conservation of the DNA binding domain which contains an invariant WRKYGQK amino acid sequence and a zinc

binding motif. However, the overall sequences of individual representatives are highly divergent. Little is known

about the 3D-structure of the WRKY proteins. Up to date there have only been results of structural strudies of

DNA binding domain available. In this review, the biological function as well the structural studies of the WRKY

proteins have been recapitulated.
