Abstract
<p> The natural phytotoxin coronatine, which is composed of two individual parts, coronafacic acid and coronamic acid, exhibits various promising biological activities similar to jasmonoyl L-isoleucine, which is one of the phytohormones, through interacting COI1-JAZ complex receptor. Interestingly, coronatine induces stomatal opening in which jasmonoyl L-isoleucine is not involved as an endogenous regulator. Moreover, a diastereomer of coronatine had stomatal opening activity but did not interact with COI1-JAZ complex protein. In addition, the mutated plant lacking the function of COI1 protein, retained stomatal opening activity by coronatine. From these data, we hypothesized coronatine would have a target protein other than jasmonate receptor in the guard cells. To identify the target protein, we synthesized alkyne-tagged coronatine for Raman imaging in living guard cells. </p>
