#Unit 6. System Physiology – Plant

The systemic production of proteinase inhibitors in young tomato plants is triggered by a complex sequence of events such as;
1) Prosystemin is proteolytically processed to produce the short polypeptide called systemin
2) Systemin is then transported out of the wounded leaf via the phloem.
3) systemin is believed to bind to a site on the plasma membrane and initiate the biosynthesis of jasmonic acid
4) Wounded tomato leaves synthesize prosystemin, a large recursor protein
5) Systemin is released from damaged cells into the apoplast
6) Jasmonic acid eventually activates the expression of genes that encode proteinase inhibitors
Arrange the correct sequence of given above following statements ;
