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.

Ferric/ferrous measurements of minerals can now be used to constrain magmatic volatile activities because synchrotron microXANES spectroscopy enables relevant measurements to be made. We introduce some of the problems to which SmX can be applied.
