Medicinal plants as the important source of secondary metabolites widely used for food industry, pharmaceutical, cosmetic, personal care and cleaning industries for its flavouring and fragrance (Gedif and Hahn, 2002; Badal et al., 2011). Lamiaceae family is one of the most important families in medicinal plants, and Mentha piperita L. (common name peppermint) has special significance in this family (Silva, 2002; Mahmoud and Croteau, 2003). This species is natural hybrid between species M. spicata L. (2n=36 or 48) and M. aquatica L. (2n=96) (Gobert et al., 2002). Peppermint as an important medicinal andaromatic plant had the economic importance hence grown in large areas in the world (Herro and Jacob, 2010). Peppermint generally growth in damp, shaded and earth has abundant water (Burbott and Loomis, 1967). Peppermint oil containing a large number of important terpenoids such as menthol, …show more content…

However, the amount of peppermint essential oil and its constituents were impacted by different factors such as water deficit (Khorasaninejad et al., 2011), climate, soil type and geographical area (Yazdani et al., 2002) harvest time and fertility (Niakan et al., 2004; Tabatabaie and Nazari, 2007; Heidari et al., 2008). Having a clear vision about relationships between enzymes transcripts and metabolites produced, the aim of the present study was to evaluate whether water stress treatment affects expression of genes of menthofuran biosynthetic pathways and menthol (highlighted in Figure 1), menthofuran content and whether an interaction between peppermint expression of genes of menthofuran biosynthetic pathway and menthol, menthofuran does
