Special Issue Information

Dear Colleagues, 

Climate change and escalating anthropogenic pressures are intensifying biotic and abiotic stresses on plants. Understanding the dual role of plant innate immunity, as both a defense mechanism against pathogens and a regulator of stress adaptation, has emerged as a critical frontier in sustainable agriculture. Innate immunity not only protects plants from microbial invasions but also intersects with pathways that mitigate abiotic stressors such as drought, salinity, and extreme temperatures. This integrative capacity positions innate immunity as a cornerstone for engineering resilient crops in a rapidly changing environment.

This Topic, “Innate Immunity and Stress Responses in Plants: Mechanisms and Resilience”, aims to synthesize cutting-edge research on the molecular, physiological, and ecological mechanisms by which plants coordinate immune and stress-responsive networks to survive under adverse conditions. We seek to unravel how these systems synergize to optimize resource allocation, balance growth-defense trade-offs, and enhance resilience.

We invite original research articles, reviews, and perspectives addressing, but not limited to, the following themes:

  1. Molecular mechanisms of innate immunity: Receptor-like kinases (RLKs), nucleotide-binding leucine-rich repeat (NLR) proteins, pathogen-associated molecular pattern (PAMP)-triggered immunity (PTI), and effector-triggered immunity (ETI).
  2. Cross-kingdom signaling: Interactions between immune pathways (e.g., salicylic acid, jasmonic acid, ethylene) and abiotic stress signals (e.g., ROS, Ca2+, ABA).
  3. Systemic acquired resistance (SAR) and priming: Long-distance signaling, metabolic reprogramming, and stress memory.
  4. Ecological and evolutionary dynamics: Role of microbial communities, endophytes, and plant–microbe interactions in shaping immune-stress resilience.
  5. Biotechnological innovations: CRISPR-based editing, synthetic biology, and omics-driven approaches to engineer dual stress-tolerant crops.
  6. Field applications: Development of bioinoculants, biostimulants, and agroecological practices leveraging innate immunity for sustainable farming.

This Topic will provide a platform to advance our understanding of plant resilience mechanisms. Manuscripts will undergo rigorous peer review to ensure scientific rigor and relevance.

We eagerly anticipate your contributions to this vital scientific discourse.

Chromatin remodelers play essential roles in modulating nucleosome structure and enabling dynamic transcriptional control. Arabidopsis calmodulin-binding transcription activators CAMTA1/2/3 negatively regulate plant immunity by suppressing the expression of biosynthesis genes of major defence hormones salicylic acid (SA) and N-hydroxy-pipecolic acid (NHP). The autoimmunity of the camta2/3 mutant is partially suppressed by loss of the NHP biosynthesis enzyme SAR deficient 4 (SARD4). During a forward genetic screen with the mildly autoimmune camta2/3 sard4 mutant, we identified chromatin-remodelling factor 5 (chr5) as its partial suppressor. The chr5 single mutants displayed decreased SA biosynthesis and compromised basal immunity. Further RNA-sequencing with chr5 defined immune-related genes that were downregulated in the mutants, including those involved in SA and NHP biosynthesis and signalling, PTI and ETI pathways. Our analysis highlights the roles of CHR5 in immune-specific chromatin remodelling events, contributing to transcriptional reprogramming during plant defence responses. Full article
