NPR1 Antibody

1. This work uncovers a strategy in which Pseudomonas syringae AvrPtoB targets Arabidopsis NPR1 and represses NPR1-dependent salicylic acid signaling, thereby subverting plant innate immunity. PMID: 29174403

3. We identified a rice mutant in the Kitaake genetic background with a frameshift mutation in crk10; this mutant also displays a compromised immune response highlighting the important role of crk10. We also show that elevated levels of NH1 expression lead to enhanced CRK10 expression and that the rice TGA2.1 protein binds to the CRK10 promoter. PMID: 27176732

12. Fusarium head blight (FHB) severity and mycotoxin accumulation were curtailed in wheat plants treated with SA and in AtNPR1 wheat, which is hyper-responsive to salicylic acid (SA). PMID: 22112217
13. Expression of the gene encoding the noexpresser of PR genes 1 (NPR1), a key component of the salicylic acid-signaling pathway, was downregulated by GASA5 overexpression. PMID: 21835493

19. NPR1 is the receptor for salicylic acid. PMID: 22813739
20. The results suggest that clade I TGA factors are required for resistance against virulent pathogens and avirulent pathogens mediated by at least some R gene specificities, acting substantially through NPR1-independent pathways. PMID: 22876961
21. The NONEXPRESSOR OF PATHOGENESIS-RELATED GENES1 (npr1) mutant, defective in cylic acid signaling, is impaired in both the production and the perception of the volatile signals, demonstrating a key role for NPR1 as a central regulator of genome stability. PMID: 22028460
22. These results show that the pathogen-triggered or salicylic acid-induced nuclear translocation is prevented by accumulation of hydrogen peroxide in the cytosol. PMID: 21051935
23. Data show that the cacao TcNPR1 gene partially complemented the npr1 mutation in transgenic Arabidopsis plants, resulting in 100 fold less bacterial growth in a leaf infection assay. PMID: 21078185
24. Mutations if npr1 alleles interact with the paralogs preventing their function in salicylic acid signalling. PMID: 20561252
25. NPR1 is S-nitrosylated after treatment with the NO donor S-nitrosoglutathione. PMID: 20716698
26. plant proteins bind to NPR1 in vivo and inhibit transcriptional activation of new proteins. PMID: 19825560
27. While NPR1 has a positive effect on pathogen resistance, it has a negative effect on symbiotic interactions, by inhibiting root hair deformation and nodulin expression. PMID: 20027302
28. Results indicate that the NLS and nuclear localization of NPR1 are required for regulation of SA tolerance, ICS1 expression and SA accumulation. PMID: 19716624
29. Cell death phenotypes in the autophagy-defective mutants are dependent on the salicylic acid signal transducer NPR1. PMID: 19773385
30. Our results strongly suggest that NIMIN1 negatively regulates distinct functions of NPR1, providing a mechanism to modulate specific features of SAR. PMID: 15749762
31. in addition to controlling expression of pathogenesis-related genes, NPR1 controls expression of the protein secretory pathway genes; findings show that NPR1 coordinately regulates these secretion-related genes through a previously undescribed cis-element PMID: 15890886
32. NPR1 is required for expression of genes involved in signal transduction after treatment with salicylic acid PMID: 16307367
