Fusicoccin Receptors in Plants — How Much do We Know for Sure ?
The wilt-inducing toxin of Fusicoccum amygdali, fusicoccin (FC) has long been used as a tool in plant physiology (Marré 1979). FC instantaneously hyperpolarizes the membrane potential and produces a strong acidification of the apoplastic space. As a result of toxin application, the transport of many metabolites and ions across the plasmalemma may change and, in accord with the acid-growth hypothesis, cell elongation may also be stimulated.
