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 …

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 …

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 …

Untersuchungen zur Funktion einer Lipoxygenase in der induzierten Resistenz bei Reis
The phenomenon of systemic acquired resistance (SAR) can be induced by the application of chemical substances like BTH, which is considered as a functional analogue of salicylic acid. Acquired resistance in plants leads to a long-lasting protection against a broad range of pathogens. However, 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 host immunity to cause disease. It’s necessary to understand the host-bacterial interactions as it is also a potential strategic hotspot for developing the novel therapeutic interventions against infectious diseases (Rana et al., 2015).</p><p>Many animal and plant pathogenic bacteria …

Biochemische und molekularbiologische Untersuchungen zur Beteiligung reaktiver Sauerstoffspezies (ROS) am Wirkungsmechanismus der systemisch erworbenen Resistenz (SAR) in Arabidopsis thaliana (L.) Heynh
Systemic Acquired Resistance (SAR) can be conditioned in Arabidopsis by chemical and biological activators. This acquired resistance to a subsequent infection manifests itself as a phenocopy of the Hypersensitive Reaction (HR) and is correlated with an increased expression of so-called PR genes, …
