common bean (Phaseolus vulgaris L.), rice (Oryza sativa L.), and Arabidopsis thaliana (L.) Heynh., demonstraPlants possess a range of defenses that can be actively expressed ting that SAR was conserved across diverse plant famiin response to pathogens and parasites of various scales, ranging from microscopic viruses to insect herbivores. The timing of these defense lies and was effective agains...

induction of systemic resistance to cucumber against marginal leaf blight disease caused by pseudomonas marginalis using silicon application (as 1 &2 mm of sodium silicate) was studied under greenhouse conditions. results indicated that application of 2 mm of sodium silicate remarkably increased resistance in cucumber against the pathogen. according to the results, disease severity in plants tr...

Genome-wide microarray analyses revealed that during biological activation of systemic acquired resistance (SAR) in Arabidopsis, the transcript levels of several hundred plant genes were consistently up- (SAR(+) genes) or down-regulated (SAR(-) genes) in systemic, non-inoculated leaf tissue. This transcriptional reprogramming fully depended on the SAR regulator FLAVIN-DEPENDENT MONOOXYGENASE1 (...

Systemic acquired resistance (SAR) is a form of inducible resistance that is triggered in systemic healthy tissues of locally infected plants. The nature of the mobile signal that travels through the phloem from the site of infection to establish systemic immunity has been sought after for decades. Several candidate signaling molecules have emerged in the past two years, including the methylate...

Systemic acquired resistance (SAR) is a general defense response in plants that is characterized by the expression of pathogenesis-related (PR) genes. SAR can be induced after a hypersensitive response to an avirulent pathogen or by treatment with either salicylic acid (SA) or 2,Cdichloroisonicotinic acid (INA). To dissect the signal transduction pathway of SAR, we isolated an Arabidopsis mutan...
