Annual Review of Phytopathology, 1997
▪ Abstract This paper examines induced resistance (SAR) in plants against various insect and pathogenic invaders. SAR confers quantitative protection against a broad spectrum of microorganisms in a manner comparable to immunization in mammals, although the underlying mechanisms differ.

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.

Annual Review of Phytopathology, 2004
▪ Abstract Systemic acquired resistance (SAR) is a mechanism of induced defense that confers long-lasting protection against a broad spectrum of microorganisms. SAR requires the signal molecule salicylic acid (SA) and is associated with accumulation of pathogenesis-related proteins, which are thought to contribute to resistance. Much progress has been

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

The Epigenetic Machinery Controlling Transgenerational Systemic Acquired Resistance [PDF]
Plant Signaling and Behavior, 2012 Progeny from diseased Arabidopsis shows enhanced resistance, which is associated with priming of defense genes. This transgenerational systemic acquired resistance (SAR) is effective against biotrophic pathogens, such as the downy mildew pathogen Hyaloperonospora arabidopsidis.

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

Requirement of Salicylic Acid for the Induction of Systemic Acquired Resistance
Science, 1993It has been proposed that salicylic acid acts as an endogenous signal responsible for inducing systemic acquired resistance in plants. The contribution of salicylic acid to systemic acquired resistance was investigated in transgenic tobacco plants harboring a bacterial gene encoding salicylate hydroxylase, which converts salicylic acid to catechol ...

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 ...

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 ...
