The first peptide to be produced after wounding in the tomato plant is ________.
Systemin
Systemin, an 18-amino-acid peptide discovered in tomato in 1991, is the first peptide hormone released when the plant is wounded (for example by insects).
It triggers jasmonic acid signalling and the production of defence proteins. Ricin is a toxin from castor seeds, and jasmonic and salicylic acids are not peptides.
