Morphophysiology and Transcriptomic Profile of Terpene Synthases Related to Essential Oil Composition in the Polyploid Complex Lippia alba Under Saline  Conditions
Lippia alba (Mill) N.E. Brown is a medicinal species whose essential oil composition isassociated with ploidal levels. Polyploidy and environmental variations can lead to significantchanges in the metabolic pathway and consequently influence the phenotype. Understandingthe spectrum of such variation requires specific experimental conditions showing thepossibility of modulating essential oil production. The combination of polyploidy withenvironmental stress creates suitable circumstances to observe the influence of two importantfactors on the evolution and production of plants. Here, three ploidal levels were cultivated invitro under salt stress (60 mM of NaCl). Morphological, biochemical, and physiological traitswere evaluated, as well. After 40 days of culture, we observed saline stress can modulate theprimary and secondary metabolism.
