Abstract
We recently identified jasmonate glucoside (Leaf-closing Factor: LCF), a β-D-glucopyranoside of 12-OH JA, as a bioactive metabolite controlling nyctinastic leaf movement of Samanea saman, which has been used as a model plant in the studies on nyctinastic leaf movement of legumes. The bioactivity of LCF is completely different from other jasmonate derivatives. Here, we demonstrate that JA activity mediated through the COI1-JAZs signalling module and leaf-closing activity (with cell-shrinking acitivity) of JA glucoside might belong to independent signalling pathways. However, COI1-JAZ-dependent and independent signaling pathways may exists in the same plant side by side, as our results demonstrate because S. saman is responding to both LCF and JA in different mechanisms based on independent signalling modules. Our result implies the existence of an additional mode of action on jasmonates.
