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

Match the following lipid linked proteins (column I) with their function (Column II).

Column I	Column II
A. prenylated proteins	i. These proteins are located in a number of subcellular compartments, including the cytosol, the endoplasmic reticulum, the inner face of the plasma membrane, and the nucleus.
B. fatty acylated proteins	ii. The core structure of these proteins consists of phosphatidylinositol glycosidically linked to a linear tetrasaccharide composed of three mannose residues and one glucosaminyl residue.
C. glycosylphosphatidylinositol-linked proteins	iii. The proteins that have covalently attached lipids that are built from isoprene units
