Methyl salicylate production and jasmonate signaling are not essential for systemic acquired resistance in Arabidopsis.
Systemic acquired resistance (SAR) develops in response to local microbial leaf inoculation and renders the whole plant more resistant to subsequent pathogen infection. Accumulation of salicylic acid (SA) in noninfected plant parts is required for SAR, and methyl salicylate (MeSA) and jasmonate (JA) are proposed to have critical roles during SAR long-distance signaling from inoculated to distan...
متن کاملThe Arabidopsis mediator complex subunit16 positively regulates salicylate-mediated systemic acquired resistance and jasmonate/ethylene-induced defense pathways.
Systemic acquired resistance (SAR) is a long-lasting plant immunity against a broad spectrum of pathogens. Biological induction of SAR requires the signal molecule salicylic acid (SA) and involves profound transcriptional changes that are largely controlled by the transcription coactivator nonexpressor of pathogenesis-related genes1 (NPR1). However, it is unclear how SAR signals are transduced ...
متن کاملSystemic acquired resistance: turning local infection into global defense.
Systemic acquired resistance (SAR) is an induced immune mechanism in plants. Unlike vertebrate adaptive immunity, SAR is broad spectrum, with no specificity to the initial infection. An avirulent pathogen causing local programmed cell death can induce SAR through generation of mobile signals, accumulation of the defense hormone salicylic acid, and secretion of the antimicrobial PR (pathogenesis...
متن کاملInterconnection between methyl salicylate and lipid-based long-distance signaling during the development of systemic acquired resistance in Arabidopsis and tobacco.
Systemic acquired resistance (SAR) is a salicylic acid (SA)-dependent heightened state of resistance against a broad spectrum of pathogens activated in the uninoculated systemic tissue of a pathogen-infected plant. For systemic protection to be initiated, a mobile signal that is produced at the site of primary infection needs to travel through the plant. Although the mobile signal (s) for SAR h...
