In aromatic plants species, biosynthesis of essential oils oocurs through two complex natural biochemical pathways involving different enzymatic reactions. Isopentenyl diphosphate (IPP) and its isomer dimethylallyl diphosphate (DMAPP) are the universal precursors of essential oils biosynthesis and are produced by the cytosolic enzymatic MVA (mevalonic acid) pathway or by plastidic and enzymatic 1-deoxy-D-xylolose-5-phosphate (DXP), also called the 2-Cmethylerythritol 4-phosphate (MEP) pathway. In the particular plant cell part, prenyl diphosphate synthases condense isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) further to form prenyl diphosphates, which are used as substrates for geranyl diphosphate, C 10 (GPP) or for fernesyl diphosphate, C 15 (FPP). Essential oils are final terpenoid products and are formed by a huge group of enzymes known as terpene synthases (TPS). Essential oils are important secondary metabolites of plants and have been used not only in different industries but also in ethnobotanical medicines for centuries. Hence, considerable research has been undertaken to understand the essential oils biosynthetic pathways. This review will be a valuable source of information in the field of natural products as we give detailed insights about biosynthesis of essential oils in plants, and thus indicate also new unexplored horizons for further research.

“…The development of advanced molecular tools and the existence of several conserved domains between TPS proteins gave rise to the cloning of a vast array of genes encoding TPSs from different plant species (e.g., Clarkia breweri [Dudareva et al, 1996], Lycopersicon esculentum [Colby et al, 1998], Salvia officinalis [Wise et al, 1998], Abies grandis [Bohlmann et al, 1999], Artemisia annua [Mercke et al, 1999], Zea mays [Shen et al, 2000], Elaeis oleifera [Shah and Cha, 2000], Mentha spp [Lange et al, 2000], Arabidopsis thaliana [Aubourg et al, 2002], Citrus limon [Lücker et al, 2002], and Cichorium intybus ; see also Bohlmann et al, 1998).…”

Terpenoid Metabolism in Wild-Type and Transgenic Arabidopsis Plants[W]

Volatile components, such as terpenoids, are emitted from aerial parts of plants and play a major role in the interaction between plants and their environment. Analysis of the composition and emission pattern of volatiles in the model plant Arabidopsis showed that a range of volatile components are released, primarily from flowers. Most of the volatiles detected were monoterpenes and sesquiterpenes, which in contrast to other volatiles showed a diurnal emission pattern. The active terpenoid metabolism in wild-type Arabidopsis provoked us to conduct an additional set of experiments in which transgenic Arabidopsis overexpressing two different terpene synthases were generated. Leaves of transgenic plants constitutively expressing a dual linalool/nerolidol synthase in the plastids (FaNES1) produced linalool and its glycosylated and hydroxylated derivatives. The sum of glycosylated components was in some of the transgenic lines up to 40-to 60-fold higher than the sum of the corresponding free alcohols. Surprisingly, we also detected the production and emission of nerolidol, albeit at a low level, suggesting that a small pool of its precursor farnesyl diphosphate is present in the plastids. Transgenic lines with strong transgene expression showed growth retardation, possibly as a result of the depletion of isoprenoid precursors in the plastids. In dual-choice assays with Myzus persicae , the FaNES1 -expressing lines significantly repelled the aphids. Overexpression of a typical cytosolic sesquiterpene synthase resulted in the production of only trace amounts of the expected sesquiterpene, suggesting tight control of the cytosolic pool of farnesyl diphosphate, the precursor for sesquiterpenoid biosynthesis. This study further demonstrates the value of Arabidopsis for studies of the biosynthesis and ecological role of terpenoids and provides new insights into their metabolism in wild-type and transgenic plants.

“…A gene with structural features common to many terpene synthases was found in the oil palm Elaeis oleifera (Shah and Cha, 2000) but remains otherwise uncharacterized. In maize, a diterpene synthase gene (an1) involved in the synthesis of gibberellins was identified by the analysis of gibberellin-sensitive transposon insertion mutants (Bensen et al, 1995).…”

The Maize Geneterpene synthase 1Encodes a Sesquiterpene Synthase Catalyzing the Formation of (E)-β-Farnesene, (E)-Nerolidol, and (E,E)-Farnesol after Herbivore Damage

et al. 2002

Maize (Zea mays) emits a mixture of volatile compounds upon attack by the Egyptian cotton leafworm (Spodoptera littoralis). These substances, primarily mono-and sesquiterpenes, are used by parasitic wasps to locate the lepidopteran larvae, which are their natural hosts. This interaction among plant, lepidopteran larvae, and hymenopteran parasitoids benefits the plant and has been termed indirect defense. The committed step in the biosynthesis of the different skeletal types of mono-and sesquiterpenes is catalyzed by terpene synthases, a class of enzymes that forms a large variety of mono-and sesquiterpene products from prenyl diphosphate precursors. We isolated a terpene synthase gene, terpene synthase 1 (tps1), from maize that exhibits only a low degree of sequence identity to previously identified terpene synthases. Upon expression in a bacterial system, the encoded enzyme produced the acyclic sesquiterpenes, (E)-␤-farnesene, (E,E)-farnesol, and (3R)-(E)-nerolidol, the last an intermediate in the formation of (3E)-4,8-dimethyl-1,3,7-nonatriene. Both (E)-␤-farnesene and (3E)-4,8-dimethyl-1,3,7-nonatriene are prominent compounds of the maize volatile blend that is emitted after herbivore damage. The biochemical characteristics of the encoded enzyme are similar to those of terpene synthases from both gymnosperms and dicotyledonous angiosperms, suggesting that catalysis involves a similar electrophilic reaction mechanism. The transcript level of tps1 in the maize cv B73 was elevated after herbivory, mechanical damage, and treatment with elicitors. In contrast, the increase in the transcript level of the tps1 gene or gene homolog in the maize cv Delprim after herbivory was less pronounced, suggesting that the regulation of terpene synthase expression may vary among maize varieties.
