Partial sequence of a monoterpene synthase (MTS) was isolated for the first time.
Mono\triterpene biosynthetic genes were differentially expressed in different tissues.
Abiotic elicitors up regulated the biosynthetic genes of monterpenes and triterpenes.
Expression of terpene biosynthetic genes is regulated in a tissue specific manner.
Elicitation is useful to produce the pharmaceutically active mono/triterpenes.
