Figure 24.7 shows the analysis of a polypeptide hydrolysate by ion-exchange chromatography.

FIGURE 24.7 Analysis of a mixture of amino acids by ion-exchange chromatography using Amberlite IR-120, a sulfonated polystyrene resin. The resin contains phenyl-SO3-Na+ groups. The amino acid mixture is applied to the column at low pH (3.25), conditions under which the acidic amino acids (Asp, Glu) are weakly bound to the resin and the basic amino acids (Lys, His, Arg) are tightly bound. Sodium citrate buffers of two different concentrations and three different values of pH are used to elute the amino acids from the column. Cysteine is determined as cystine, Cy-S-S-Cys, the disulfide of cysteine.

The systemic production of proteinase inhibitors in young tomato plants is triggered by a complex sequence of events (Figure 23.20):

Wounded tomato leaves synthesize prosystemin, a large (200 amino acids) precursor protein.

Prosystemin is proteolytically processed to produce the short (18 amino acids) polypeptide DAMP called systemin.

Systemin is released from damaged cells into the apoplast.

In adjacent intact tissue (phloem parenchyma), systemin binds to a pattern recognition receptor on the plasma membrane.

The activated systemin receptor becomes phosphorylated and activates a phospholipase A2 (PLA2).

The activated PLA2 generates the signal that initiates JA biosynthesis.

JA is then transported through the phloem to systemic parts of the plant by an unknown mechanism.

JA is taken up by target tissues and activates the expression of genes that encourage proteinase inhibitors.
