Light Influences How the Fungal Toxin Deoxynivalenol Affects Plant Cell Death and Defense Responses [PDF]

, 2014
The Fusarium mycotoxin deoxynivalenol (DON) can cause cell death in wheat (Triticum aestivum), but can also reduce the level of cell death caused by heat shock in Arabidopsis (Arabidopsis thaliana) cell cultures.

TIR innovations in plant immunity

New Phytologist, EarlyView.
Summary Toll/interleukin‐1 receptor (TIR) domain‐containing immune receptors are crucial for plant immunity, with recent advancements highlighting the enzymatic functions of TIR domains and their production of signaling molecules. TIR‐catalyzed compounds interact with receptors to form functional modules that trigger the oligomerization of helper ...

NPR1 in Plant Defense: It's Not over 'til It's Turned over [PDF]

Cell, 2009
NPR1 is a key transcriptional coregulator in plant defense responses. In this issue, Spoel et al. (2009) demonstrate that proteasome-mediated degradation of NPR1 in the nucleus promotes efficient expression of defense response genes following infection and prevents spurious activation of defensive responses in the absence of infection.

NPR1-Independent Activation of Immediate Early Salicylic Acid-Responsive Genes in Arabidopsis

Molecular Plant-Microbe Interactions, 2004
Salicylic acid (SA) is a key signal for the activation of defense genes in response to stress. The activation of late defense genes by SA, such as PR-1, involves the participation of the NPR1 protein.

Redox regulation of LSD1/CATALASE 2 phase separation condensates controls location and functions

New Phytologist, EarlyView.
Summary Phase separation of proteins into membraneless compartments is emerging as an important mechanism of plant developmental and stress responses. We show Arabidopsis catalase 2 (CAT2) is recruited to phase‐separated condensates with LESION SIMULATING DISEASE1 (LSD1), a plant‐specific regulator of programmed cell death, in a redox‐dependent manner ...

Integrating Data on the Arabidopsis NPR1/NPR3/NPR4 Salicylic Acid Receptors; a Differentiating Argument

Frontiers in Plant Science, 2015
Salicylic acid (SA) is a mandatory plant metabolite in the deployment of systemic acquired resistance (SAR), a broad-spectrum systemic immune response induced by local inoculation with avirulent pathogens.

A module with multiple transcription factors positively regulates powdery mildew resistance in grapevine

Plant Biotechnology Journal, EarlyView.
Summary Erysiphe necator, the causal agent of powdery mildew (PM), is a fungal pathogen that can severely reduce crop yields. In this study, stable overexpression and silencing demonstrated that the transcription factor VqWRKY46 was identified as a positive regulator of PM resistance in grapevine.

High‐permeability cellulose nanocrystals mediate systemic zinc redistribution through nsLTP2‐dependent immune potentiation in plants

Plant Biotechnology Journal, EarlyView.
Summary Zinc (Zn2+) is an essential micronutrient that regulates plant growth, immunity and antiviral defence mechanisms. However, its limited bioavailability often necessitates excessive application, resulting in inefficiencies in production and environmental stress.
