Is ozone flux inside leaves only a damage indicator? Clues from volatile isoprenoid studies.
Tropospheric ozone is increasing at a fast pace and causes large losses of production in cultivated plants and forests (UNECE, 2004). Ozone risk assessment has been based for a long time on exposure to external ozone concentration. Doses above a selected threshold (generally 40 nL L) have been considered injurious, and the cumulated exposure to these concentrations has been the basis of the lev...
متن کاملMetabolic flux analysis of plastidic isoprenoid biosynthesis in poplar leaves emitting and nonemitting isoprene.
The plastidic 2-C-methyl-D-erythritol-4-phosphate (MEP) pathway is one of the most important pathways in plants and produces a large variety of essential isoprenoids. Its regulation, however, is still not well understood. Using the stable isotope 13C-labeling technique, we analyzed the carbon fluxes through the MEP pathway and into the major plastidic isoprenoid products in isoprene-emitting an...

متن کاملVolatile organic compounds from leaves litter.
Qualitative composition of volatile emissions of litter of five species of deciduous trees was investigated by GC-MS. The list of identified substances contains more than 70 organic compounds of various classes. It was established that the composition of components emitted by the litter into the gas phase greatly differs from that of essential oils extracted by hydrodistillation from turned lea...
متن کاملVolatile constituents of essential oils isolated from flowers and leaves of Eupatorium cannabinum L. from Iran
Hydro-distilled volatile oils from the flowers and leaves of Eupatorium cannabinum L. which gathered in Touchal on Mountain Alborz (Tehran province) in Iran were investigated mainly by a combination of GC and GC/MS. Thirty-nine components were identified in the oils. The main constituents of the essential oils in flowers and leaves were germacrene D (27.3%, 37.1%), gemacrene B (12.4%, 11.7%) an...
