84 results about "WRKY transcription factor" patented technology

The WRKY transcription factor family (pronounced ‘worky’) is a class of DNA-binding proteins. WRKY transcription factors are primarily specific to plants and algae (Viridiplantae); although, individual WRKY proteins do appear in the human protozoan parasite Giardia lamblia and slime mold Dictyostelium discoideum. These transcription factors recognize a (T/A)TGAC(T/A) cis-regulatory element, also known as a W-box, in the promoters of target genes. WRKY transcription factors play a major role in plant defense to abiotic and biotic stresses, but also contribute to plant development and secondary metabolism. These roles are governed by an ever increasingly complex network of interactions with other DNA-binding and non-DNA-binding proteins.
