PPT-WRKY transcription factors in potato genome

factors in potato genome Background WRKY proteins are a superfamily of transcription factors involved in various physiologial processes in plants including pathogen defence WRKY transciption factors have been shown to act as both negative and positive regulators of defence suggesting that they may operate through different regulatory complexes The different roles can be partly determined by the topological features of the proteins . and Its Regulation.
