Summary:
Sesquiterpenes are a large family of C15 isoprenoids, found in bacteria, fungi, insects and plants. They are derived from farnesyl diphosphate (FPP) or nerolidyl diphosphate by the action of enzymes called sesquiterpene synthases. The synthesis of sesquiterpenes from FPP is localized in the cytosol/endoplasmic reticulum boundary. E-bF occurs in a number of plants and is known to play a role in chemical communication. The well studied farnesene in aphids acts as a pheromones and deters predators. The biosynthesis of EbF in Mentha presents the possibility of engineering the EbS gene into other plants. The production of aphid deflecting farnesene products would provide the much needed defence against aphid infestation of plants [Prosser06].

The cis-calamenene sesquiterpenoids are found in the foliage of Cupressus bakeri as natural products. They are also isolated from Madagascan shrub Tarenna madagascariensis (Rubiaceae) [Salmoun07].
