IntroductionMedicinal and aromatic plants are effective with their active ingredients (Kamel, 2000). Several essential oils of such plants have antimicrobial, carminative, chlorotic, sedative, diuretic, and antispasmodic impacts in various diseases (Maksimovic et al., 2005). Peppermint cultivars contain menthone, isomenthone, carvone, and pulegone and all these peppermint essential oils have antimicrobial characteristics. They are also used as active ingredients in toothpastes, food stuffs, soaps, creams, lotions, and perfumes (Sivropoulou et al., 1995;Baydar, 2013).Nitrogen treatments are commonly used worldwide in plant culture to improve the yields (Ladha et al., 2005). Nitrogenous and phosphorus fertilizers may also improve essential oil yield and quality of medicinal and aromatic plants (

“…() provided evidence that the increased accumulation of phytochemicals, such as rosmarinic and caffeic acids in sweet basil, was mediated by direct effects of the AM fungi, and not solely as an indirect result of improved P nutrition. Increased production of essential oils in coriander, dill, oregano, sweet basil, valerian, fennel or mint colonized by AM fungi has also been described (Kapoor et al ., ; Freitas et al ., ; Toussaint et al ., ; Morone‐Fortunato & Avato, ; Prasad et al ., ). Some mechanisms have been suggested for the increase of essential oils due to mycorrhizal colonization.…”

The establishment and growth of Rosmarinus officinalis L. under field conditions in two low‐nutrient‐content soils were evaluated, as well as the effect of arbuscular mycorrhizal (AM) fungi on essential oil production. The reclamation was conducted in two experimental sites: a limestone quarry and a wasteland soil, both surrounded by Mediterranean vegetation. Mycorrhizal R. officinalis plants inoculated with different AM fungal isolates were used to revegetate the sites. Pre‐transplant inoculation with mycorrhizal fungi resulted in an increased survival of R. officinalis with similar results in both experimental areas. Mycorrhizal inoculation enhanced plant growth, increased essential oil yield and improved the establishment of plants under field conditions. The results indicate that the presence of the symbiosis can accelerate plant growth and alter the biosynthesis of secondary metabolites, thus improving the yield of medicinal plant extracts. It also confirmed the importance of selecting plant/symbiont combinations adapted to the environmental constraints of low‐nutrient‐content soils to design a successful application of mycorrhizal technology in marginal soils.

“…The content of linalool, geranial, 10-epi-γ-eudesmol, and citronellol in geranium oil increased and that of cis-and trans-rose oxide decreased by inoculation with PSB alone or in combination with AM fungi as compared to uninoculated controls. The changes in various constituents in the EOs of all inoculated and fertilized geranium plants could be related to the enhanced uptake of P and divalent metallic cations in plant tissues (Prasad et al 2012).…”

“…The synergistic effects of combined inoculation of PGPRs with AM fungi have been reported on the production of EOs in plants. According to Prasad et al (2012), the chemical composition of geranium oil was significantly affected by inoculation with phosphate-solubilizing bacteria (PSB) and/or AM fungi and phosphate fertilization. The content of linalool, geranial, 10-epi-γ-eudesmol, and citronellol in geranium oil increased and that of cis-and trans-rose oxide decreased by inoculation with PSB alone or in combination with AM fungi as compared to uninoculated controls.…”

Other than nutritional value for human and livestock, plants have gained significant attention in recent years due to their secondary metabolites, which are widely used in aromatic, therapeutic, or chemical industries. Higher plants use primary metabolites such as carbohydrates, lipids, and amino acids to synthesize various secondary metabolites that serve a variety of functions including plant defense against herbivores and microbes, protection against environmental stresses, and contribution to specific odors, tastes, and colors in plants (Seigler 1998). Plant secondary metabolites are unique sources for food additives, flavors, fragrances, and pharmaceuticals (Bennett and Wallsgrove 1994; Ravishankar and Rao 2000). Plants accumulate secondary metabolites mostly under stress conditions in response to various biotic and abiotic elicitors or signal molecules. Physiological traits and genetic diversity, environmental conditions, geographic variation, and evolution are among the main factors affecting the accumulation and composition of secondary metabolites (Figueiredo et al. 2008). Moreover, infection by microorganisms and abiotic factors such as osmotic stresses can induce particular secondary metabolite pathways in plants (Sanchez et al. 2004).
