Description
Pawel Poznanski and three co-authors study how chitosan, a shell-derived compound, wakes up barley defenses, in this 2024 paper. Chitosan sprays are known to fight fungi, trigger plant immunity, and boost growth, but the batch traits vary. The team picked their strongest antifungal batch and asked what it does inside the plant.
Barley sprayed with the batch showed whole-plant resistance: tiny dead spots formed where a rust fungus attacked, and a second fungus caused milder disease. Growth rose by eleven to fifteen percent. The spray also raised salicylic acid, a hormone that steers both defense and growth. Doses of that hormone alone copied the effect, and gene readings showed its pathways switched on. The authors conclude the hormone carries chitosan's benefits, a clue for designing greener crop sprays.
