Abstract

COS-OGA is a new elicitor that combines oligochitosan and oligopectates in presence of calcium ions. Elicitation of tomato plants with COS-OGA has been tested and resulted in leaf peroxidase activity increase, transcription of SA-associated defence genes and overexpression of PR,
heat-shock and DNA/RNA remodelling proteins. Greenhouse and field trials confirmed the efficacy of
the elicitor against powdery mildew on cucumber and grapevine.
