e1“The synthesis of precursors of lignin such as p-coumaric, ferulic, and sinapic acids and phenolic acids having antimicrobial activity such as benzoic, p-coumaric, caffeic, protocatechuic, chlorogenic, ferulic, and gallic acids was also stimulated by chitosan treatment”

Other claims from this paper (11)
- Intervention effect Chitosan treatment (2-8 mg/mL) significantly improved seed germination of two spring wheat cultivars at concentrations above 4 mg/mL relative to the control.
- Intervention effect Seed-borne Fusarium graminearum was reduced to below 50 percent at higher chitosan treatments compared with the control.
- Intervention effect Chitosan treatment stimulated the synthesis of phenolic acids in primary wheat leaves.
- Association Levels of phenolic acids, especially ferulic acid, increased significantly with increasing chitosan concentration.
- Intervention effect Chitosan inhibited fungal transmission to the primary roots of germinating wheat seedlings.
- Mechanism The authors suggest that chitosan increased seedling resistance to F. graminearum by stimulating phenolic and lignin accumulation.
- Observation Lignin content of primary wheat leaves showed a similar pattern to the chitosan-induced phenolic acids.
- Association The chitosan-induced accumulation of phenolic acids and lignin was significantly lower in cultivar Max than in Norseman.
- Intervention effect Chitosan treatment stimulated the synthesis of phenolic acids with antimicrobial activity: benzoic, p-coumaric and caffeic acids.
- Intervention effect Chitosan treatment stimulated the synthesis of phenolic acids with antimicrobial activity: protocatechuic, chlorogenic and ferulic acids.
- Intervention effect Chitosan treatment stimulated the synthesis of the phenolic acid gallic acid.
