Protein
Hydroxyproline-rich systemin
Gene
N/A
Organism
Solanum lycopersicum (Tomato) (Lycopersicon esculentum)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Activates a lipid-based signal transduction pathway in which linolenic acid is converted to jasmonic acid, a potent activator of defense gene transcription. Induces synthesis of proteinase inhibitors I and II in leaves when supplied through cut stems.1 Publication
