Phosphorylation and Nuclear Localization of NPR1 in Systemic Acquired Resistance.
When plants sense a pathogen attack, they activate defenses in the immediate area and in distaltissues;thissystemicacquiredresistance (SAR) requires salicylic acid (SA), which activatesNONEXPRESSEROFPATHOGENESISRELATED GENES1 (NPR1) in Arabidopsis thaliana (reviewed in Fu and Dong, 2013). This activation involves the release of NPR1 monomers from oligomers, which is also regulated by the cell’s...
متن کاملStrong suppression of systemic acquired resistance in Arabidopsis by NRR is dependent on its ability to interact with NPR1 and its putative repression domain.
Systemic Acquired Resistance (SAR) in plants confers lasting broad-spectrum resistance to pathogens and requires the phytohormone salicylic acid (SA). Arabidopsis NPR1/NIM1 is a key regulator of the SAR response. Studies attempting to reveal the function of NPR1 and how it mediates SA signaling have led to isolation of two classes of proteins that interact with NPR1: the first class includes ri...
متن کاملThe Arabidopsis NPR1 Gene That Controls Systemic Acquired Resistance Encodes a Novel Protein Containing Ankyrin Repeats
The Arabidopsis NPR1 gene controls the onset of systemic acquired resistance (SAR), a plant immunity, to a broad spectrum of pathogens that is normally established after a primary exposure to avirulent pathogens. Mutants with defects in NPR1 fail to respond to various SAR-inducing treatments, displaying little expression of pathogenesis-related (PR) genes and exhibiting increased susceptibility...
متن کاملInducers of Plant Systemic Acquired Resistance Regulate NPR1 Function through Redox Changes
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 ...
متن کاملArabidopsis TCP Transcription Factors Interact with the SUMO Conjugating Machinery in Nuclear Foci
In Arabidopsis more than 400 proteins have been identified as SUMO targets, both in vivo and in vitro. Among others, transcription factors (TFs) are common targets for SUMO conjugation. Here we aimed to exhaustively screen for TFs that interact with the SUMO machinery using an arrayed yeast two-hybrid library containing more than 1,100 TFs. We identified 76 interactors that foremost interact wi...
