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 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 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 کاملResistance to turnip crinkle virus in Arabidopsis is regulated by two host genes and is salicylic acid dependent but NPR1, ethylene, and jasmonate independent.
Inoculation of turnip crinkle virus (TCV) on the resistant Arabidopsis ecotype Dijon (Di-17) results in the development of a hypersensitive response (HR) on the inoculated leaves. To assess the role of the recently cloned HRT gene in conferring resistance, we monitored both HR and resistance (lack of viral spread to systemic tissues) in the progeny of a cross between resistant Di-17 and suscept...
متن کاملThe Arabidopsis NIMIN proteins affect NPR1 differentially
NON-EXPRESSOR OF PATHOGENESIS-RELATED GENES1 (NPR1) is the central regulator of the pathogen defense reaction systemic acquired resistance (SAR). NPR1 acts by sensing the SAR signal molecule salicylic acid (SA) to induce expression of PATHOGENESIS-RELATED (PR) genes. Mechanistically, NPR1 is the core of a transcription complex interacting with TGA transcription factors and NIM1-INTERACTING (NIM...
