Outline of Final Research Achievements

Plant hormones function as signalling compounds which defend against environmental stresses or herbivore damage. Especially, jasmonic acid (JA) and its related metabolites work in the herbivore damaged leaves. Recent studies have shown that JA its self is inactive, but its isoleucine conjugate (JA-Ile) is active. It has been known that herbivore damage can activate plants defense at distant tissues, and signalling compounds may control the whole-plant defense induction. Highly mobile MeJA can be a candidate as the whole-plant defensive signalling molecule. In this study, transportation of MeJA and its activation into JA-Ile in the distant tissues (upper leaves) were investigated using an experimental mode plant Achyranthes bidentata (Ox knee). Exogenously applied MeJA was transported into upper distant leaves and activated into JA-Ile. Induced defensive terpene metabolites in the distant leaves were shown to be de-novo metabolites.
