Systemic acquired resistance, NPR1, and pathogenesis-related genes in wheat and barley

Journal of Integrative Agriculture, 2018
In Arabidopsis, systemic acquired resistance (SAR) is established beyond the initial infection by a pathogen or is directly induced by treatment with salicylic acid (SA) or its functional analogs, 2,6-dichloroisonicotinic acid (INA) and benzothiadiazole (

Systemic Acquired Resistance [PDF]

Plant Physiology, 1994
In the spectrum of plant-microbe interactions disease is a rare outcome. In many interactions complex, integrated defense mechanisms prevent infection and disease. These defensive systems include preformed physical and chemical barriers as well as inducible defenses such as the strengthening of cell walls or synthesis of antimicrobial compounds (i.e ...

Beneficial Microorganisms as a Sustainable Alternative for Mitigating Biotic Stresses in Crops

Stresses, 2023
Nowadays, population growth, the global temperature increase, and the appearance of emerging diseases in important crops generate uncertainty regarding world food security.

Characterization of a Novel, Defense-Related Arabidopsis Mutant, cir1, Isolated By Luciferase Imaging

Molecular Plant-Microbe Interactions, 2002
In order to identify components of the defense signaling network engaged following attempted pathogen invasion, we generated a novel PR-1∷luciferase (LUC) transgenic line that was deployed in an imaging-based screen to uncover defense-related mutants ...

Systemic Acquired Resistance [PDF]

Plant Signaling & Behavior, 2006
Upon infection with necrotizing pathogens many plants develop an enhanced resistance to further pathogen attack also in the uninoculated organs. This type of enhanced resistance is referred to as systemic acquired resistance (SAR). In the SAR state, plants are primed (sensitized) to more quickly and more effectively activate defense responses the ...

Two PR-1 Genes from Tomato Are Differentially Regulated and Reveal a Novel Mode of Expression for a Pathogenesis-Related Gene During the Hypersensitive Response and Development

Molecular Plant-Microbe Interactions, 1997
Pathogenesis-related (PR) proteins form a heterogeneous family of plant proteins that are likely to be involved in defense and are inducible by pathogen attacks.

Induced plant resistance [PDF]

Ratarstvo i Povrtarstvo, 2012
Plants have evolved different strategies to protect themselves against pathogen infections. These strategies are classified as either passive or active, depending on whether they are constitutive barriers or triggered upon pathogen attack.

1007 SYSTEMIC ACQUIRED RESISTANCE [PDF]

HortScience, 1994
Systemic acquired resistance is a broad spectrum inducible defense response that is associated with the expression of a set of genes (SAR genes). Expression of one of these genes (PR-1a from tobacco) in transgenic tobacco confers increased tolerance to two oomycete pathogens.

Redox regulation of the NPR1-TGA1 system of Arabidopsis thaliana by nitric oxide [PDF]

, 2010
The role of reactive oxygen and nitrogen species in local and systemic defense reactions is well documented. NPR1 and TGA1 are key redox-controlled regulators of systemic acquired resistance in plants. NPR1 monomers interact with the reduced form of TGA1,

Characterization of a New Arabidopsis Mutant Exhibiting Enhanced Disease Resistance

Molecular Plant-Microbe Interactions, 1999
In many plant-pathogen interactions, resistance is associated with the synthesis and accumulation of salicylic acid (SA) and pathogenesis-related (PR) proteins.
