In recent research for bioactive substances of Arabidopsis thaliana, seven new oxylipins named arabidopsides A-G were isolated from the aerial parts of this plant. Arabidopsides A-G were monogalactosyl diacylglycerides or digalactosyl diacylglycerides containing 12-oxophytodienoic acid and/or dinor-oxophytodienoic acid which were known as precursors of jasmonic acid (JA) and have received much attention because they play important roles in regulation of developmental and defense gene expression of plants as JA and methyl jasmonate. In this research, we investigated the effect of heavy metals as potent inducers for triggering accumulations of arabidopsides A-G in mature leaves of A. thaliana. In addition, heavy metals-induced arabidopsides were not detected in the coi 1-1 mutant. These results indicate that heavy metals-induced arabidopsides are concerned in the mechanism of stress response through COI 1 signaling in A. thaliana.
