Octadecanoid-derived phytohormones, such as jasmonates and 12-oxophytodienoic acid (OPDA; 1) as well as their synthetic analogues (Scheme 1), induce various physiological responses in tissues and cell cultures of different plant species. [1,2] Although jasmonates are known to mediate abiotic and biotic stress including wounding, and pathogen and herbivore attack, there is only limited knowledge about jasmonate-induced signaling pathways that initiate subsequent cellular responses. Circumstantial and indirect evidence suggests that changes in the concentration of free Ca 2+ in the cytosol might be induced downstream of the jasmonate signal. [3,4] Such data may extend to jasmonate signaling the
