Product Description
Diterpene glucoside with numerous effects on plants. Induces H+ extrusion from plant cells by 14-3-3-dependent activation of the plasma membrane H+-ATPase. Stimulates cell enlargement, ion uptake, seed germination, opening the stomata, etc. Markedly reduces the cell’s capability for H2O2 scavenging.
