The gene is thought to be regulated by three transcription factors: a TGA-bZIP factor and an unknown factor that activate transcription, and a WRKY factor that represses transcription []. SNI1 is a negative regulator of gene expression, possibly acting through the WRKY factor. (b) NPR1 regulates gene expression through interactions with the TGA-bZIP factor, and possibly with the other two transcription factors and/or with SNI1. Common regulation of genes in the regulon is proposed to occur through WRKY transcription factors acting either positively or negatively and in an NPR1-dependent fashion. Dashed lines indicate putative interactions.
