Inducers of plant systemic acquired resistance regulate NPR1 function through redox changes.

Cell - 27 Jun 2003

Mou Zhonglin, Fan Weihua, Dong Xinnian

Abstract excerpt

NPR1 is an essential regulator of plant systemic acquired resistance (SAR), which confers immunity to a broad-spectrum of pathogens. SAR induction results in accumulation of the signal molecule salicylic acid (SA), which induces defense gene expression via activation of NPR1. We found that in an uninduced state, NPR1 is present as an oligomer formed through intermolecular disulfide bonds. Upon SAR induction, a...
