Systemin, an 18-amino acid polypeptide, has been isolated from tomato leaves that is a powerful inducer of over 15 defensive genes.
Systemin is readily transported from wound sites and is considered to be the primary systemic signal.The signal transduction pathway that mediates Systemin signaling involves linolenic acid release from membranes and subsequent conversion to jasmonic acid, a potent activator of defense gene transcription. The pathway exhibits analogies to arachidonic acid/prostaglandin signaling in animals that leads to inflammatory and acute phase responses[1]. Systemin, an 18-amino-acid peptide signal. Systemin is cleaved from the C-terminal region of a 200-amino acid precursor protein called proSystemin. Following the cloning of proSystemin gene, which represents a single locus in the tomato genome, several lines of genetic evidence indicate that Systemin acts as an upstream component of wound-induced signaling cascades leading to defense gene expression[2].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
