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.

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 (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).

Jasmonate before salicylate in systemic acquired resistance
Trends in Plant ScienceSystemic acquired resistance (SAR) has long been viewed as a salicylate-driven process. Recent evidence by Gaikwad et al. reveals an earlier, jasmonate- and calcium (Ca2+)-dependent systemic phase that precedes salicylate accumulation. This temporal dynamic refines prevailing models of jasmonate-salicylate crosstalk and suggests a previously ...

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 ...

The transcriptome of Arabidopsis thaliana during systemic acquired resistance
Nature Genetics, 2000Infected plants undergo transcriptional reprogramming during initiation of both local defence and systemic acquired resistance (SAR). We monitored gene-expression changes in Arabidopsis thaliana under 14 different SAR-inducing or SAR-repressing conditions using a DNA microarray representing approximately 25-30% of all A. thaliana genes.

The Molecular Biology of Systemic Acquired Resistance
1993Depletion of in planta salicylic acid in transgenic salicylate hydroxylase (NahG)containing plants, has shown that this phenolic compound is essential for expression of several modes of plant disease resistance. These include i) the rapid defense response found in some cases of genetically determined resistance, ii) the manifestation of disease ...

Chapter 5 Systemic Acquired Resistance
2009Abstract Systemic acquired resistance (SAR) is a form of induced resistance that is activated by pathogens that induce localized necrotic disease lesions or a hypersensitive response. A major characteristic of SAR is the broad spectrum nature of the protection it confers against a wide range of pathogens, although recent studies suggest that the ...
