Abstract—
The reactions to ozone of the surface cells of leaves and needles of five introduced wood species of Sochi National Park in chronic 3-day exposure in total doses of up to 0.05 μL/L have been studied. In secretory structures of silvery or ashen leaves of Eucalyptus cinerea F. Muell. Ex. Benth, we observed noticeable changes in absorbance (fading) and autofluorescence in cells. Blue and silvery needles of Picea pungens Engelm species. cv. Sv, Cedrus atlantica (Endl.) Manetti ex Carrière cv. Argentea, Pinus parviflora Siebold &Zucc. Glauca and leaves of Acacia dealbata Link. were not sensitive to ozone in the above-mentioned reactions. It was shown that the surface layers of the cuticle and cell wall of these plants included azulenes. These pigments are supposed to be primary targets for ozone, and their antioxidant properties determine low sensitivity to ozone.
期刊介绍：
Biochemistry (Moscow), Supplement Series A: Membrane and Cell Biology is an international peer reviewed journal that publishes original articles on physical, chemical, and molecular mechanisms that underlie basic properties of biological membranes and mediate membrane-related cellular functions. The primary topics of the journal are membrane structure, mechanisms of membrane transport, bioenergetics and photobiology, intracellular signaling as well as membrane aspects of cell biology, immunology, and medicine. The journal is multidisciplinary and gives preference to those articles that employ a variety of experimental approaches, basically in biophysics but also in biochemistry, cytology, and molecular biology. The journal publishes articles that strive for unveiling membrane and cellular functions through innovative theoretical models and computer simulations.
