Calcium‐dependent protein kinase 5 links calcium signaling with N‐hydroxy‐l‐pipecolic acid‐ and SARD1‐dependent immune memory in systemic acquired resistance [PDF]

, 2019
Systemic acquired resistance (SAR) prepares infected plants for faster and stronger defense activation upon subsequent attacks. SAR requires an information relay from primary infection to distal tissue and the initiation and maintenance of a self ...

Systemic Activation of the Antioxidant System by Root Priming With Non‐Pathogenic Fusarium oxysporum in Flax Infected With Pathogenic Fusarium oxysporum

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Fusarium oxysporum Fo47 primes flax by locally suppressing pathogens in roots and systemically activating antioxidant defences in shoots, offering a sustainable plant protection strategy. ABSTRACT Plants rely on specialised adaptive mechanisms to enhance resistance against environmental stress.

Exploring plant tolerance to biotic and abiotic stresses [PDF]

, 2007
Plants are exposed to many stress factors, such as drought, high salinity or pathogens, which reduce the yield of the cultivated plants or affect the quality of the harvested products. Arabidopsis thaliana was used as a model plant to study the responses

Salicylic acid receptor NPR1 is involved in guard cell chitosan signaling

Bioscience, Biotechnology, and Biochemistry, 2020
Abstract Chitosan (CHT) induces stomatal closure and thus plays a crucial role in plants to adapt to the adverse environments. Our previous results of a SA-deficient mutant nahG suggest that endogenous salicylic acid (SA) is involved in the CHT signaling in guard cells.

Transcriptional outputs and condensates – formation and function

New Phytologist, Volume 249, Issue 3, Page 1145-1154, February 2026.
Summary The dynamic spatiotemporal organization of macromolecules is key to the proper function of the cell, allowing the exquisite regulation of diverse processes from gene expression to enzymatic function. The formation of biomolecular condensates via phase separation (PS) acts as a general mechanism for selectively concentrating proteins, nucleic ...

The NPR1-dependent salicylic acid signalling pathway is pivotal for enhanced salt and oxidative stress tolerance in Arabidopsis [PDF]

, 2017
NPR1-dependent salicylic acid signalling controls sodium entry into the roots while preventing potassium loss through depolarization-activated outward-rectifying potassium and ROS-activated non-selective cation channels during salt and oxidative ...

Calmodulin-binding transcription activator AtSR1/CAMTA3 fine-tunes plant immune response by transcriptional regulation of the salicylate receptor NPR1.

Plant, Cell and Environment, 2020
Calcium (Ca2+ ) signaling regulates salicylic acid (SA)-mediated immune response through calmodulin-meditated transcriptional activators, AtSRs/CAMTAs, but its mechanism is not fully understood.

Insect I‐Type Lysozymes Function as Antiviral Proteases by Forming Biomolecular Condensates

Advanced Science, Volume 13, Issue 1, 5 January 2026.
Upon rice viral infection, the insect vector activates the Toll–MyD88–Dorsal signaling cascade, inducing i‐type lysozyme (Lyz‐I1) expression. Lyz‐I1 functions as an antiviral protease through its conserved catalytic dyad Glu/Asp (E/D), mediating cleavage of viral proteins at specific Lys (K) residues.

A new mode of NPR1 action via an NB‐ARC–NPR1 fusion protein negatively regulates the defence response in wheat to stem rust pathogen

New Phytologist, 2020
Summary NPR1 has been found to be a key transcriptional regulator in some plant defence responses. There are nine NPR1 homologues (TaNPR1) in wheat, but little research has been done to understand the function of those NPR1‐like genes in the wheat ...
