Role of SABP2 in Systemic Acquired Resistance Induced by Acibenzolar-S-Methyl in Plants.
… available chemical inducer of local and systemic resistance (SAR) response in plants. ASM functioning at molecular level is mostly unclear. This research was designed to investigate the mechanism of ASM action in plants. It was hypothesized that SABP2, a plant protein, plays an important …

The Molecular Consequences of CK2-mediated Phosphorylation of the TGA2 Transcription Factor within Systemic Acquired Resistance of Arabidopsis thaliana
… by the pathogen and in more distal tissue. Systemic acquired resistance (SAR) is a type of systemic defence response deployed against biotrophic pathogens resulting in altered plant gene expression and production of antimicrobial compounds. One such gene involved in plant defence is called …

TGA2 dual activity: N-terminus regulation of reversible DNA binding influenced by NPRI and CK2
TGA2 is a dual-function Systemic Acquired Resistance (SAR) transcription factor involved in the activation and repression of pathogenesis-related (PR) genes. Recent studies have shown that TGA2 is able to switch from a basal repressor to activator, likely, through regulatory control from its …

Synthesis of Novel Agrochemicals as Potential Plant Immunization Agents.
… several pathogens. These compounds induce systemic acquired resistance (SAR) in plants, leading to broad-based, long-lasting resistance to a wide range of pathogens. The salicylic acid binding protein 2 (SABP 2) has been identified as a key enzyme in the salicylic acid mediated pathogen …

Large-scale studies and biophysical analysis of systems involved in plant immunity.
… suppression of basal immunity. In the realm of systemic acquired resistance (SAR), we have demonstrated that clade I TGA recruits a specific novel glutaredoxin as a corepressor to dampen the expression of a set of SAR-regulated genes controlled by salicylic acid (SA) and the SAR-orchestrator, …

Characterization of Host Plant Defense Responses to Parasitization by <I>Orobanche aegyptiaca</I>
… Genes analyzed that are associated with systemic defense include <I>PR-1</I>, <I>PR-2</I>, and <I>PR-5</I>, all of which are induced in response to pathogen attack as part of the systemic acquired resistance (SAR) response. Plant gene expression was studied using transgenic tomato plants …

Study and Manipulation of the Salicylic Acid-Dependent Defense Pathway in Plants Parasitized by Orobanche aegyptiaca Pers.
… acid (SA)-mediated defense pathway that leads to systemic acquired resistance (SAR). The objective of this research was to extend the characterization of PR gene expression in order to define the scope of host defense response. Analyses of gene expression using RNA hybridization and RT-PCR in …

Characterization and insights into the molecular mechanism of cytokinin-induced priming of plant defenses
… much stronger. This mechanism of induced disease resistance can be initiated by biological and chemical agents. The major benefit of priming is the induction of a high level of protection with considerably low fitness costs making it an attractive disease management strategy to preserve …

Structural Investigation of Bacterial Pathogenesis and Host Immune Response
… the innate immunity of individual cells and on systemic signals emanating from the infection sites (Dodds & Rathjen, 2010). NPR1 (NONEXPRESSOR OF PATHOGENESIS-RELATED GENES 1) is a master immune regulator in plants. It orchestrates systemic acquired resistance (SAR) by activating …

Characterization of the Pathway Leading to the Synthesis of Salicylic Acid in Plants Resisting Pathogen Infection.
<p>Salicylic acid is a plant hormone that accumulates with plant-pathogen interaction. This accumulation corresponds to the plant being resistant to infection and without it the plant is susceptible. In this study, primers of genes involved in the normal synthesis of SA were used in RT-PCR to …

Subcellular Localization of Tobacco Salicylic Acid Binding Protein 2 in Plants.
<p>Salicylic Acid Binding Protein 2 (SABP2) is a 29kDa protein present in extremely low amounts in tobacco leaves. SABP2 processes the mobile defense signal, methyl salicylic acid generated in plants resisting microbial infection. The precise localization of SABP2 in plants is not known. SABP2 has …

Soybean aphid intra-biotype variability based on colonization of specific soybean genotypes, resistance responses of soybean genotypes to pathogen infection after the application of chemical elicitors, and resistance to charcoal rot identified in ancestral soybean germplasm
… for managing this pest is through host plant resistance. Since its arrival in 2000, four aphid biotypes have been identified that are able to overcome soybean aphid resistance (Rag) genes. A soybean aphid isolate collected from Moline, Illinois was not biotype 1 or biotype 2 because it readily …
