Research Abstract

We synthesized four stereo-hybrids of molecular probe bbased on the structure of JAG. JAG promotes ROS production in Samanea motor cell, a model motor cell of plant, and then activate outward-directed K+-channel. However, different mechanism can be involved in the rapid leaf-closure of Dionaea.
