The extraction of plant essential oils (EOs) and analysis by gas chromatography coupled to mass spectrometry (GC-MS) are standard methods when studying aromatic plants and the chemical composition of EOs. Here, two simple methods for the extraction of EO compounds from leaves of Thymus vulgaris are described. Organic solvent extraction and solid-phase microextraction (SPME), respectively, are used and the results of the GC-MS analyses are compared.We explain how analyte peaks can be identified and discuss possible rearrangement reactions that can occur during the extraction process or analysis.

Transcription factors with programmable DNA-binding specificity constitute valuable tools for the design of orthogonal gene regulatory networks for synthetic biology. Transcription activator-like effectors (TALEs), as natural transcription regulators, were used to design, build, and test libraries of synthetic TALE-activated promoters (STAPs) that show a broad range of expression levels in plants. In this chapter, we present protocols for the construction of artificial TALEs and corresponding STAPs.

Plant glandular trichomes are specialized secretory structures located on the surface of the aerial parts of plants with large biosynthetic capacity, often with terpenoids as output molecules. The collection of plant trichomes requires a method to separate trichomes from leaf epidermal tissues. For metabolite profiling, trichome tissue needs to be rapidly quenched in order to maintain the indigenous state of intracellular intermediates. Appropriate extraction and chromatographic separation methods must be available, which address the wide-ranging polarity of metabolites. In this chapter, a protocol for trichome harvest using a frozen paint brush is presented. A work flow for broad-range metabolite profiling using LC-MS2 analysis is described, which is applicable to assess very hydrophilic isoprenoid precursors as well as more hydrophobic metabolites from trichomes and other plant tissues.
