Depolarization of tomato leaf cells by oligogalacturonide elicitors

, : Depolarization of tomato leaf cells by oligogalacturonide elicitors. Plant Cell & Environment 18(2): 211-214

The electrical potential difference (E-m) across the plasma membrane of tomato leaf mesophyll cells consists of a cyanide-sensitive component, presumably produced by an H+-ATPase, and a cyanide-insensitive component. Variation of E-m between different batches of tissue is mainly caused by variation in the cyanide-sensitive component. Oligogalacturonide elicitors that induce the synthesis of proteinase inhibitors in tomato seedlings depolarize the E-m of tomato leaf mesophyll cells. This depolarization closely resembles that caused by cyanide: they are of similar magnitude and vary in a similar manner with variation in the initial E-m of different batches of tissue. Treatments with cyanide and with the elicitors have similar effects on the small depolarization caused by KCl at 10 mol m-3. The results suggest that the elicitors depolarize E-m by inhibiting the plasma membrane H+-ATPase, but that the detailed mechanism of inhibition by the elicitors is different from that caused by cyanide.
