Fusicoccin is a phytotoxin originally isolated from F. amygdali that induces death of tomato plants when used at concentrations ranging from 0.1 to 0.2 ?g/ml.{43094} Topical administration of fusicoccin to tobacco (N. tabacum), sorghum (S. bicolor), cucumber (C. sativa), lucerne (M. sativa), and pokeweed (P. Americana) induces permanent opening of leaf stomata and wilting.{43095} Fusicoccin binds to the preformed complex between plasma membrane H+-ATPase and a 14-3-3 protein in plants to stabilize and activate the enzyme leading to dysregulated solute transport and control of transmembrane electric potential.{43096} It also stabilizes eukaryotic 14-3-3 protein interactions with binding partners containing a C-terminal 14-3-3 recognition motif, also known as a mode 3 motif, such as ER?, GPIb?, TASK3, CTFR, and p53 in vitro.{43097} Fusicoccin stimulates cortical neurite outgrowth in a 14-3-3 protein-dependent manner (EC50 = 29 ?M).{43098} In vivo, topical administration of fusicoccin to the injury site reduces collapse and retraction of severed axons in a mouse model of spinal cord injury.
