This review establishes Ca2+, ROS and NO signalling as an integrated feedback network that links pathogen perception, calcium decoding, local and systemic defence, and maintenance of immune homeostasis across tissues and summarizes current knowledge of Ca2+ channels and sensor proteins involved in plant immunity.
This review systematically summarizes the evolutionary expansion, structural characteristics, classification, and activation mechanisms of plant CDPK families, and systematically compare CDPK functional uniqueness relative to parallel Ca2+ sensor and kinase cascades.
Plant innate immunity is a crucial, multi-layered defense system that protects crops from a wide range of bacterial, fungal, and viral pathogens, all of which pose a significant threat to global food security. Co-receptors function as central molecular modulators that amplify and fine-tune immune signaling. This signal...

A metabolite-guided signal fidelity hypothesis is proposed in which certain specialized metabolites act as molecular stabilizers in the response of organisms to stress and buffer transient ROS bursts, limit variability in calcium signaling, and strengthen hormone-regulated feedback loops.

Current knowledge of RLK structural diversity, signal transduction mechanisms, and network integration is synthesized, highlighting their central role in cell wall integrity surveillance, stress adaptation, and emerging strategies for engineering climate-resilient crops.
In Arabidopsis thaliana, the SGN3 receptor kinase and CIF peptides, known for their roles in Casparian strip surveillance in the root endodermis, also function in leaves during effector-triggered immunity to control lignin barrier formation and disease resistance.
