Resumen:
information for clarifying the functionality of secondary metabolites. Essential oils are secondarymetabolites produced and stored in secretory structures on leaves, flowers, and steam. Many studieshave shown that the chemical composition of the essential oil can differ depending on the plantorgan and the secretory structures even if they are at the same organ. Such differences may be theconsequence that organs also differ in type and density of glandular structure. Moreover, the same typeof glandular structure can change its chemical composition depending on its position within the sameorgan. However, no study has been evaluating the chemical composition of the essential oil from thesame glandular structure in leaves and fertile floral whorls. The aim of this work was to characterizethe chemical composition of essential oils of peltate glandular trichomes from anthers and leaves ofLepechinia floribunda. We found a lower richness of chemical compounds and higher relative abundanceof monoterpene hydrocarbons on anthers than leaves. Leaves showed an increased relative abundanceof oxygenated sesquiterpenes. Such differences probably respond to a high tissue-specificity expressionof genes in different plant organs.
