A plant RNA virus inhibits NPR1 sumoylation and subverts NPR1-mediated plant immunity
Nature Communications, 2023 NONEXPRESSER OF PATHOGENESIS-RELATED GENES 1 (NPR1) is the master regulator of salicylic acid-mediated basal and systemic acquired resistance in plants.

The Arabidopsis NIMIN proteins affect NPR1 differentially [PDF]
Frontiers in Plant Science, 2013 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 ...

NPR1 paralogs of Arabidopsis and their role in salicylic acid perception.
PLoS ONE, 2018 Salicylic acid (SA) is responsible for certain plant defence responses and NON EXPRESSER OF PATHOGENESIS RELATED 1 (NPR1) is the master regulator of SA perception. In Arabidopsis thaliana there are five paralogs of NPR1.

NPR1 as a transgenic crop protection strategy in horticultural species [PDF]
Horticulture Research, 2018 Plant immunity: Engineering for enhanced resistance Introducing the plant immunity gene NPR1 into fruits and vegetables may help to protect them against diseases and pests, which are emerging and migrating faster than resistance can be developed using ...

Low level of polymorphism in two putative
Biology Direct, 2010 Background Grapevine is subjected to numerous pests and diseases resulting in the use of phytochemicals in large quantities. The will to decrease the use of phytochemicals leads to attempts to find alternative strategies, implying knowledge of defence ...

NPR1 Has Everything under Control [PDF]
Plant Physiology, 2019 NONEXPRESSER OF PR GENES1 (NPR1) controls plant immunity and is key to salicylic acid (SA)-dependent signaling pathways. First identified via a genetic screen, NPR1 is named after the npr1 mutants that failed to activate PATHOGENESIS-RELATED ( PR ) gene expression and were, therefore, defective ...

Nuclear Localization of NPR1 Is Required for Activation of PR Gene Expression [PDF]
The Plant Cell, 2000 Systemic acquired resistance (SAR) is a broad-spectrum resistance in plants that involves the upregulation of a battery of pathogenesis-related (PR) genes. NPR1 is a key regulator in the signal transduction pathway that leads to SAR. Mutations in NPR1 result in a failure to induce PR genes in systemic tissues and a heightened susceptibility to pathogen

Structural basis of NPR1 in activating plant immunity
Nature, 2022 NPR1 is a master regulator of the defence transcriptome induced by the plant immune signal salicylic acid1-4. Despite the important role of NPR1 in plant immunity5-7, understanding of its regulatory mechanisms has been hindered by a lack of structural information.

The cpr5 mutant of Arabidopsis expresses both NPR1-dependent and NPR1-independent resistance. [PDF]
The Plant Cell, 1997 The cpr5 mutant was identified from a screen for constitutive expression of systemic acquired resistance (SAR). This single recessive mutation also leads to spontaneous expression of chlorotic lesions and reduced trichome development. The cpr5 plants were found to be constitutively resistant to two virulent pathogens, Pseudomonas syringae pv maculicola
