Identification and functional characterization of three new terpene synthase genes involved in chemical defense and abiotic stresses in Santalum album.

Multifunctional enzymes were biochemically characterized, including one chloroplastic mono-TPS and two cytosolic sesqui-TPSs in sandalwood. Our results suggest the ecological importance of these three new SaTPS genes in defensive response to biotic attack and abiotic stresses in S. album.
