Abstract
In tomato leaves, excision and light treatments increase phenylalanine ammonia-lyase activity, which is contributed by three PAL isoforms. These isoforms possessed similar native and subunit Mr, but were different in their pI, Km for Phe and optimal pH for activity. Also these were differentially induced and affected by metabolites belonging to particular branches of phenylpropanoid pathway.
