What is The Activation Mechanism of Chitosan Oligosaccharide On The Plant Immune System?(1)

6ceee67fcc321d6081968ab4abf265e Chitosan Oligosaccharide – a natural bioactive compound derived from crustacean shells – revolutionizes plant protection by triggering innate immune responses. 

The “Smart Defense System” of Immune Activation

G-Teck Chitosan Oligosaccharide (COS) (Deacetylation ≥95%, Molecular Weight ≤3000Da) leverage their unique small oligosaccharide chain structure to act as a “natural activation code” for plant immune systems.

Precise Recognition: Bind to LYK/CERK receptors on plant cell membranes, triggering receptor-like kinase (RLKs) signaling to initiate immune alerts. 

Phenylalanine Ammonia-Lyase (PAL) activity increases by 50%, accelerating phytoalexin (e.g., resveratrol) synthesis.

Chitinase secretion triples, directly degrading pathogen cell walls.

Systemic Acquired Resistance (SAR): Activates both salicylic acid (SA) and jasmonic acid (JA) pathways, inducing 20+ defense-related proteins to establish “whole-plant immunity.”

82.7% efficacy against tomato leaf mold .

Rice sheath blight infection reduced by 67%, with glutathione peroxidase (GPX) activity increasing by 140%.
