Systemic acquired resistance signal transduction
Critical Reviews in Plant Sciences, 1996Abstract Systemic acquired resistance (SAR) is an inducible plant defense response in which a prior foliar pathogen infection activates resistance in noninfected foliar tissues. Salicylic acid (SA) accumulation is essential for the establishment of SAR.

Redox control of systemic acquired resistance
Current Opinion in Plant Biology, 2005Changes in gene expression during systemic acquired resistance (SAR) require the phenolic signaling molecule salicylic acid (SA) and are modulated by the interaction between the NON EXPRESSOR OF PATHOGENESIS-RELATED GENES1 (NPR1) protein and members of the TGA family of transcription factors. In the past two years, the activities of NPR1 and of the TGA

POWERDRESS positively regulates systemic acquired resistance in Arabidopsis
Plant Cell Reports, 2022PWR, an epigenetic regulator, and PIF4, a transcription factor coordinately regulate both local resistance and systemic acquired resistance in Arabidopsis. A plant that gets infected once becomes resistant to subsequent infections through the development of systemic acquired resistance (SAR). Primary-infected tissues generate mobile signals that travel

Systemic Acquired Resistance (SAR)
1998Nicotiana species and cultivars possessing the dominant N gene, e.g. Nicotiana glutinosa, N. tabacum “Samsun NN” and N. tabacum “Xanthi nc”, produce necrotic local lesions upon inoculation with the type strain of tobacco mosaic Tobamovirus (TMV).

Genetic dissection of systemic acquired resistance
Current Opinion in Plant Biology, 2001Significant progress has been made in the past year in understanding the mechanism of systemic acquired resistance. Mitogen-activated protein kinase cascades have been implicated as negative regulators of salicyclic acid accumulation and the induction of resistance.

Systemic Acquired Resistance and Induced Systemic Resistance in Conventional Agriculture
Crop Science, 2004Plants possess a range of defenses that can be actively expressed in response to pathogens and parasites of various scales, ranging from microscopic viruses to insect herbivores. The timing of these defense responses is critical and can be the difference between being able to cope or succumbing to the challenge of a pathogen or parasite.

Systemic acquired resistance specific proteome of Arabidopsis thaliana
Plant Cell Reports, 2020A comparative proteomic study between WT and SAR-compromised rsi1/fld mutant reveals a set of proteins having possible roles in the SAR development. A partly infected plant shows enhanced resistance during subsequent infection through the development of systemic acquired resistance (SAR). Mobile signals generated at the site of primary infection travel

Systemic Acquired Resistance in Plants
1996The defense of plants against infectious microorganisms involves constitutive barriers as well as reactions induced upon contact with potential pathogens. Systemic acquired resistance (SAR) is characterized by an activation of a broad spectrum of host defense mechanisms, locally at the site of the initial pathogen attack as well as systemically, in ...

SOS – too many signals for systemic acquired resistance?
Trends in Plant Science, 2012Following pathogen infection, activation of systemic acquired resistance (SAR) in uninfected tissues requires transmission of a signal(s) from the infected tissue via the vasculature. Several candidates for this long-distance signal have been identified, including methyl salicylate (MeSA), an SFD1/GLY1-derived glycerol-3-phosphate (G3P)-dependent ...

Signaling by small metabolites in systemic acquired resistance
The Plant Journal, 2014SummaryPlants can retain the memory of a prior encounter with a pest. This memory confers upon a plant the ability to subsequently activate defenses more robustly when challenged by a pest. In plants that have retained the memory of a prior, localized, foliar infection by a pathogen, the pathogen‐free distal organs develop immunity against subsequent ...
