FF TGA2 is a SA-responsive and NPR1-dependent transcription activator [6];
FF Involved in the activation of GNT3 and STR246 genes ( encoding certain GSTs) in response to SA and local infection, but also have a repressor function in the pathway for PR gene induction and SAR establishment [5];
FF the binding activity of TGA2 to the as-1 element, to the positive LS7 and negative LS5 regulatory elements are enhanced by NPR1 [4] [8];
FF interacts strongly with NPR1 T04760 in vitro [7];
FF binds to the as-1 element R00009, not effected by NPR1 T04760 [7];
