Phosphorylation and Nuclear Localization of NPR1 in Systemic Acquired Resistance.
When plants sense a pathogen attack, they activate defenses in the immediate area and in distaltissues;thissystemicacquiredresistance (SAR) requires salicylic acid (SA), which activatesNONEXPRESSEROFPATHOGENESISRELATED GENES1 (NPR1) in Arabidopsis thaliana (reviewed in Fu and Dong, 2013). This activation involves the release of NPR1 monomers from oligomers, which is also regulated by the cell’s...
متن کاملThe Arabidopsis NPR1 Gene That Controls Systemic Acquired Resistance Encodes a Novel Protein Containing Ankyrin Repeats
The Arabidopsis NPR1 gene controls the onset of systemic acquired resistance (SAR), a plant immunity, to a broad spectrum of pathogens that is normally established after a primary exposure to avirulent pathogens. Mutants with defects in NPR1 fail to respond to various SAR-inducing treatments, displaying little expression of pathogenesis-related (PR) genes and exhibiting increased susceptibility...
متن کاملDiscovery of Functional Genes for Systemic Acquired Resistance in arabidopsis Thaliana through Integrated Data Mining
Various data mining techniques combined with sequence motif information in the promoter region of genes were applied to discover functional genes that are involved in the defense mechanism of systemic acquired resistance (SAR) in Arabidopsis thaliana. A series of K-Means clustering with difference-in-shape as distance measure was initially applied. A stability measure was used to validate this ...
متن کاملFitness costs of mutations affecting the systemic acquired resistance pathway in Arabidopsis thaliana.
This study investigated the fitness effects of four mutations (npr1, cpr1, cpr5, and cpr6) and two transgenic genotypes (NPR1-L and NPR1-H) affecting different points of the systemic acquired resistance (SAR) signaling pathway associated with pathogen defense in Arabidopsis thaliana. The npr1 mutation, which resulted in a failure to express SAR, had no effect on fitness under growth chamber con...
متن کاملFitness benefits of systemic acquired resistance during Hyaloperonospora parasitica infection in Arabidopsis thaliana.
We investigated the fitness benefits of systemic acquired resistance (SAR) in Arabidopsis thaliana using a mutational and transformational genetic approach. Genetic lines were designed to differ in the genes determining resistance signaling in a common genetic background. Two mutant lines (cpr1 and cpr5) constitutively activate SAR at different points in SAR signaling, and one mutant line (npr1...
