Role of NPR1 in Systemic Acquired Stomatal Immunity
Plants, 2023 Stomatal immunity is the primary gate of the plant pathogen defense system. Non-expressor of Pathogenesis Related 1 (NPR1) is the salicylic acid (SA) receptor, which is critical for stomatal defense.

NPR1 paralogs of Arabidopsis and their role in salicylic acid perception. [PDF]
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: the spider in the web of induced resistance signaling pathways. [PDF]
Current Opinion in Plant Biology, 2004 The plant hormones salicylic acid (SA), jasmonic acid (JA), and ethylene (ET) are major players in the regulation of signaling networks that are involved in induced defense responses against pathogens and insects.

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.

Dynamic ubiquitination determines transcriptional activity of the plant immune coactivator NPR1 [PDF]
eLife, 2019 Activation of systemic acquired resistance in plants is associated with transcriptome reprogramming induced by the unstable coactivator NPR1. Immune-induced ubiquitination and proteasomal degradation of NPR1 are thought to facilitate continuous delivery ...
