A New Mode of NPR1 Action via an NB-ARC–NPR1 Fusion Protein Negatively Regulates the Defence Response in Wheat to Stem Rust Pathogen [PDF]

New Phytologist, 2020
Summary NPR1 has been found to be a key transcriptional regulator in some plant defence responses. There are nine NPR1 homologues (TaNPR1) in wheat, but little research has been done to understand the function of those NPR1‐like genes in the wheat defence response against stem rust (Puccinia graminis f. sp. tritici) pathogens. We used bioinformatics

Increased SA in NPR1-Silenced Plants Antagonizes JA and JA-Dependent Direct and Indirect Defenses in Herbivore-Attacked Nicotiana attenuata in Nature

Plant Journal, 2007
non-expressor of PR-1 (NPR1) mediate pathogen resistance in many plants. Herbivore attack on Nicotiana attenuata elicits increases in JA and JA-mediated defenses, but also increases SA levels and Na-NPR1 transcripts from the plant’s single genomic copy ...

NPR1, all things considered

Current Opinion in Plant Biology, 2004
Recent work has shown that the Arabidopsis NPR1 protein not only plays an essential role in salicylic acid (SA)-mediated systemic acquired resistance and rhizobacterium-triggered induced systemic resistance, but also is involved in crosstalk inhibition of jasmonic acid (JA)-mediated defense responses.

Isolation and characterization of the rice NPR1 promoter

Plant Biotechnology Reports, 2009
NPR1 is a positive regulator of systemic acquired resistance in Arabidopsis and rice. Expression of the rice gene OsNPR1 is induced by salicylic acid (SA). To identify the region of the OsNPR1 promoter involved in response to SA, we carried out deletion mutagenesis of the region 1005 bp upstream of the OsNPR1 start codon.

Targeting NPR1: a strategy went viral

Trends in Plant Science
Non-expressor of pathogenesis-related 1 (NPR1) acts as master regulator of plant immunity by promoting salicylic acid (SA) signalling. Some bacterial and fungal pathogens target NPR1 to inhibit SA-mediated immunity. Recently, Zhang et al. and Liu et al.

Elicitor and Fusarium-induced expression of NPR1-like genes in banana

Plant Physiology and Biochemistry, 2008
The non-expressor of pathogenesis-related genes 1 (NPR1) is an essential positive regulator of salicylic acid (SA)-induced pathogenesis-related (PR) gene expression and systemic acquired resistance (SAR). Two novel full length NPR1-like genes; MNPR1A and MNPR1B, were isolated from banana by application of the PCR and rapid amplification of cDNA ends ...

Arabidopsis ein2-1 and npr1-1 Response to Al Stress

Bulletin of Environmental Contamination and Toxicology, 2014
An enhanced Al(3+) tolerance has been observed in ethylene insensitive mutant ein2-1 and salicylic acid insensitive mutant npr1-1 of Arabidopsis. However, we found that the tolerant phenotype of ein2-1 and npr1-1 under Al stress was dependent on NPR and EIN function, respectively, because the double mutant ein2-1/npr1-1 displayed more sensitive to Al ...

Molecular cloning and characterization of NPR1 gene from Arachis hypogaea

Molecular Biology Reports, 2014
The NPR1 gene was an important regulator for a plant disease resistance. The cDNA of NPR1 gene was cloned from peanut cultivar Ri Hua 1 by rapid amplification of cDNA ends-polymerase chain reaction (RACE-PCR). The full length cDNA of Arachis hypogaea NPR1 consisted of 2,078 base pairs with a 1,446 bp open-reading frame encoding 481 amino acids.

A role for salicylic acid and NPR1 in regulating cell growth in Arabidopsis

The Plant Journal, 2001
SummarySalicylic acid (SA) plays a key role in activating defenses and cell death during plant–pathogen interactions. In response to some pathogens, SA also limits the extent of cell death, indicating that it acts positively or negatively depending on the host–pathogen interaction.

Characterization and expression patterns of the NPR1-like genes in maize

Journal of Genetics
The nonexpressor of pathogenesis-related 1 (NPR1) is the salicylic acid (SA) receptor, which plays an important regulatory role in plant immunity. However, the NPR1-like gene family in maize has not been comprehensively identified and analysed. In the present study, we identified gene structures, conserved motifs, cis-elements, and expression patterns ...
