Artemisia is a large, diverse genus of plants with between 250-400 species belonging to the family Asteraceae. Because Artemisia annua contain artemisinin widely used for anti-malaria drug, sesquiterpene biosynthesis in A. annua is paid to attention. Five sesquiterpene synthases have been cloned and characterized from the plant species. In contrast to A. annua, genetic and chemical information from other Artemisia species is quite limited. As a starting point to understand the molecular basis for chemical differences among Artemisia species systematically, we performed comparative sesquiterpenoid profiling and gene expression analyses using Artemisia species. So far, we reported that sesquiterpene profile was highly correlated with gene expression between A. annua, A. afra and A. absinthum (Fig. 1.). In this study, leaves of 16 Artemisia species were collected and analyzed their terpene profiles by GC-MS. Both germacrane and caryophllane were detected in the majority of Artemisia specie, suggest that these synthases exist widely in Artemisa species. Three sesquiterpenoids with selphperfol skeleton were characteristic to A. abrotanium. In other case, sativaene skeleton was detected in A. stelleriana. From these results, novel sesquiterpene sythases should be exist in these plants species. Isolation of novel sesquiterpene sythase gene from both A. abrotanium and A. stelleriana and systematic separation procedures of sesquiterpene skeleton for Artemisia species is now in progress.
