AB: Trees produce a wide spectrum of volatile organic compounds (VOCs) including isoprene and monoterpenes, as well as oxygenated compounds like aldehydes, alcohols and carboxylic acids. Aim of the BEWA2000 project within the German joint research project AFO200 (Atmosphaeren Forschungsprogramm 2000) is to elucidate the metabolic pathways leading to the formation of these compounds, in particular volatile isoprenoids. The presentation summarises information on photosynthetic and non-photosynthetic prercursors of isoprenoid biosynthesis, as well as on metabolites and enzymes of the plastidic isoprenoid pathway in isoprene- or monoterpene-emitting poplar (Populus spec.) and Holm oak (Quercus ilex). In particular, it discusses physiological, biochemical and molecular biological aspects, which are prerequisites for the development of process-based emission models describing the biochemical and physiological reactions leading to the emission of volatile isoprenoids.
