Chemical Compositions of Aerial Part of Tagetes minuta L. Chemotype Essential Oils From Madagascar

Abstract: The chemical composition of 18 essential oil samples of the aerial parts of various flower color types of Tagetes minuta from Madagascar has been characterized by GC and GC/MS. The main components were limonene (3.6–11%), (Z)-β-ocimene (1.0–17.1%), (E)- β-ocimene (0.5–14.6%), p-cymene (0.3–20.4%), β-caryophyllene (1.1–12.7%), (Z)- tagetenone (tr-26.7%), (E)-tagetenone (tr-31.3%), α-muurolene (tr-36.5%), and verbenone (1.4–15.4%). Results show the occurrence of various chemotypes reach in tagete derivatives (up to 80%) or in terpene derivatives (up to 76%).

Isolation and Screening of Microorganisms with Potential for Biotransformation of Terpenic Substrates

Abstract: The objective of the present work was to isolate and select strains with potential to perform the biotransformation of terpenic substrates. Microorganisms obtained from a collection culture and also isolated from a natural source of terpene substrate were tested. Seventeen strains were selected by their resistance to terpenes in potato dextrose agar containing up to 1% of limonene or α-pinene and β-pinene (1:1). Subsequently, 10 strains were selected by their capacity of using these terpenes as sole carbon source in a mineral medium. The biotransformation capacity of these strains was tested and the products obtained were identified by GC-MS.

Production of terpenes and terpenoids in glandular trichome-bearing plants

Abstract: Methods for producing heterologous terpenes, terpenoids and/or small molecules in transgenic glandular trichome-bearing plants are provided, as well as the transgenic glandular trichome-bearing plants capable of producing the heterologous terpenes, terpenoids and small molecules. The genetically engineered glandular trichome-bearing plants contain and express one or more genes which encode proteins active in the biosynthetic pathways which produce the terpenes, terpenoids and small molecules. As a result, the essential oil of the transgenic plant is enriched for the heterologous or homologous terpenes, terpenoids and/or small molecules Storage of the essential oil in the glandular trichomes of the plant reduces the volatility and cytotoxic capacity of the heterologous molecules, thereby increasing yield and decreasing damage to the transgenic plant.
