Activation of an EDS1-Mediated R-Gene Pathway in the snc1 Mutant Leads to Constitutive, NPR1-Independent Pathogen Resistance

Molecular Plant-Microbe Interactions, 2001
The Arabidopsis NPR1 protein is an essential regulatory component of systemic acquired resistance (SAR). Mutations in the NPR1 gene completely block the induction of SAR by signals such as salicylic acid (SA).

Characterization of Arabidopsis enhanced disease susceptibility mutants that are affected in systemically induced resistance [PDF]

, 2001
In Arabidopsis, the rhizobacterial strain Pseudomonas fluorescens WCS417r triggers jasmonate (JA)- and ethylene (ET)-dependent induced systemic resistance (ISR) that is effective against different pathogens.

Multi‐Omics Analyses Reveal the Red and Far‐Red Light Combination Enhancing Heterologous Protein and Metabolite Production in Nicotiana benthamiana

Plant, Cell &Environment, EarlyView.
ABSTRACT Transient expression of exogenous protein in Nicotiana benthamiana leaves via agroinfiltration offers a rapid and efficient platform for functional gene discovery and heterologous production of valuable eukaryotic proteins and metabolites. Though light quality is an important factor for plant photomorphogenesis, its impact on the efficiency of

On the spectrum of S=1/2 XXX Heisenberg chain with elliptic exchange

, 1995
It is found that the Hamiltonian of S=1/2 isotropic Heisenberg chain with $N$ sites and elliptic non-nearest-neighbor exchange is diagonalized in each sector of the Hilbert space with magnetization $N/2-M ...

Interaction of NIMIN1 with NPR1 Modulates PR Gene Expression in Arabidopsis

The Plant Cell, 2005
The Arabidopsis thaliana NONEXPRESSER OF PR GENES1 (NPR1, also known as NIM1) protein is an essential positive regulator of salicylic acid (SA)-induced PATHOGENESIS-RELATED (PR) gene expression and systemic acquired resistance (SAR). PR gene activity is regulated at the level of redox-dependent nuclear transport of NPR1.

Welcome Pathogens: Transient Heat Dampens Immune Responses to Acibenzolar‐S‐Methyl in Apple Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT Climate change affects plant‐pathogen interactions, with disease outcome varying depending on the pathosystem and environmental scenario. In Arabidopsis, a thermo‐sensitive module of salicylic acid (SA) signalling makes immunity vulnerable to heat.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

The phytotoxin coronatine is a multifunctional component of the virulence armament of Pseudomonas syringae [PDF]

, 2014
Plant pathogens deploy an array of virulence factors to suppress host defense and promote pathogenicity. Numerous strains of Pseudomonas syringae produce the phytotoxin coronatine (COR).

Arabidopsis Clade I TGA Transcription Factors Regulate Plant Defenses in an NPR1-Independent Fashion

Molecular Plant-Microbe Interactions, 2012
Transcriptional reprogramming during induction of salicylic acid (SA)-mediated defenses is regulated primarily by NPR1 (NONEXPRESSOR OF PATHOGENESIS-RELATED GENES 1), likely through interactions with TGA bZIP transcription factors.

Cross-talk between signaling pathways leading to defense against pathogens and insects [PDF]

, 2008
In nature, plants interact with a wide range of organisms, some of which are harmful (e.g. pathogens, herbivorous insects), while others are beneficial (e.g.
