Journal ArticleDOI
Plants have a sensitive perception system for the most conserved domain of bacterial flagellin
TL;DR: It is demonstrated that plants have a highly sensitive chemoperception system for eubacterial flagellins, specifically targeted to the most highly conserved domain within its N terminus.
Journal ArticleDOI
The Arabidopsis NPR1 gene that controls systemic acquired resistance encodes a novel protein containing ankyrin repeats
TL;DR: Transformation of the cloned wild-type NPR1 gene into npr1 mutants not only restored the responsiveness to SAR induction with respect to PR-gene expression and resistance to infections, but also rendered the transgenic plants more resistant to infection by P. syringae in the absence of SAR induction.
Journal ArticleDOI
Roles of Salicylic Acid, Jasmonic Acid, and Ethylene in Cpr-Induced Resistance in Arabidopsis
TL;DR: Results indicate that cpr5 and cpr6 regulate resistance through distinct pathways and that SA-mediated, NPR1-independent resistance works in combination with components of the JA/ET–mediated response pathways.
Journal ArticleDOI
Isolation of New Arabidopsis Mutants With Enhanced Disease Susceptibility to Pseudomonas syringae by Direct Screening
TL;DR: The data presented here indicate that eds genes define a variety of components involved in limiting pathogen growth, that many additional EDS genes remain to be discovered, and that direct screens for mutants with altered susceptibility to pathogens are helpful in the dissection of complex pathogen response pathways in plants.
Journal ArticleDOI
Mutation of the Glucosinolate Biosynthesis Enzyme Cytochrome P450 83A1 Monooxygenase Increases Camalexin Accumulation and Powdery Mildew Resistance.
TL;DR: Accumulation of higher levels of camalexin contributes to increased resistance to powdery mildew, and overexpression of PAD3 increased camaleXin levels and enhanced resistance to G. cichoracearum.
