Fusicoccin is a phytotoxic metabolite produced by the fungus Fusicoccum (Phomopsis) amygdali, a pathogen of peach and almond plants. The interest for fusicoccin is due to its activity not confined to natural hosts of F amygdali but widespread on all higher plants. Fusicoccin induces an uncontrolled stomata opening which leads to leaf wilting and then to the plant death. This effect is due to the ability of fusicoccin to irreversible activate the plasma membrane H+-ATPase. Studies on fusicoccin, carried out for many years, besides clarifying its mechanism of action, have also shed light on the physiological regulation of the proton pump. The present review will focus the main steps of this long story.

Abstract
Fusicoccin is a phytotoxic metabolite produced by the fungus Fusicoccum (Phomopsis) amygdali, a pathogen of peach and almond plants. The interest for fusicoccin is due to its activity not confined to natural hosts of F amygdali but widespread on all higher plants. Fusicoccin induces an uncontrolled stomata opening which leads to leaf wilting and then to the plant death. This effect is due to the ability of fusicoccin to irreversible activate the plasma membrane H+-ATPase. Studies on fusicoccin, carried out for many years, besides clarifying its mechanism of action, have also shed light on the physiological regulation of the proton pump. The present review will focus the main steps of this long story.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
