Activating Compound

Activating Compound	Comment	Organism	Structure
fusicoccin	increases the interaction between the phosphorylated Vha2 and the 14-3-3 protein, followed by an enhancement of the H+-ATPase activity and citrate exudation under Al stress conditions	Vicia faba

Application

Application	Comment	Organism
agriculture	isoform Vha2 is clearly up-regulated by Al in roots of Al-resistant but not of Al-sensitive plants, whereas the transcription levels of 14-3-3 protein are elevated in a time-dependent manner in both Al-resistant and Al-sensitive roots. Greater citrate exudation is positively correlated with higher activities of plasma membrane H+-ATPase in roots of Al-resistant compared with Al-sensitive plants. Phosphorylation and interaction of Vha2 with the 14-3-3 protein are enhanced in Al-resistant roots but not in Al-sensitive roots with increasing Al treatment time. Fusicoccin or adenosine 5'-monophosphate increase or decrease the interaction between the phosphorylated Vha2 and the 14-3-3 protein, followed by an enhancement or reduction of the H+-ATPase activity and citrate exudation in both cultivars under Al stress conditions, respectively	Vicia faba
