Effects of the air pollutant SO2 on leaves: Inhibition of sulfite oxidation in the apoplast by ascorbate and of apoplastic peroxidase by sulfite
(American Society of Plant Biologists, 1992)
After SO2 has entered leaves of spinach (Spinacia oleracea) through open stomata and been hydrated in the aqueous phase of cell walls, the sulfite formed can be oxidized to sulfate by an apoplastic peroxidase that is ...
Feeding habits of huchen Hucho hucho (Salmonidae) fry in the River Tresnjica, Yugoslavia
(Taylor & Francis Ltd, Abingdon, 1998)
About 10 000 huchen larvae, obtained by artificial spawning, were introduced on 28 May 1995 into the River Tresnjica, a tributary to the River Drina, using procedures applied routinely by local fishing associations. During ...
Study of photochemical reactions of coniferyl alcohol. II. Comparative structural study of a photochemical and enzymatic polymer of coniferyl alcohol
(American Society for Photobiology, 1998)
The structure of the polymer synthesized by UV irradiation of coniferyl alcohol was studied, using UV-visible, Raman, IR, LH-NMR and C-13-NMR spectroscopy. The photochemical polymer was compared with the structure of the ...
Spontaneous ultraweak, bioluminescence in plants: Origin, mechanisms and properties
(R and D print, 1998)
An analysis of theoretical knowledge and experimental results of ultraweak luminescence (UWL) is provided. The role of excited state of molecules and free radicals, formed in various biochemical reactions, in UWL is ...
Detection of monodehydroascorbic acid radical in sulfite-treated leaves and mechanism of its formation
(Japanese Soc Plant Physiologists, Kyoto, 1998)
The aim of the present study is to detect the monodehydroascorbic acid (MDA) radical in broad bean (Vicia faba L.) leaves which were treated by vacuum-infiltration in Na2SO3 solution and subsequent centrifugation ...
A study of lignin formation at the molecular level by scanning tunneling microscopy
(Biophysical Journal, 1994)
A scanning tunneling microscope (STM) was used to observe the temporal formation and organization of dehydrogenative polymer (DHP) synthesized from coniferyl alcohol. The images obtained elucidate this structure for the ...
Study of photochemical reactions of coniferyl alcohol .1. Mechanism and intermediate products of UV radiation-induced polymerization of coniferyl alcohol
(Blackwell Publishing Inc., 1997)
Ultraviolet light-induced photochemical transformations of coniferyl alcohol have been studied, using spectrophotometric and H-1 NMR approaches. It was shown earlier that coniferyl alcohol can be polymerized not only ...
Inhibition of catalase by sulfite and oxidation of sulfite by H2O2 cooperating with ascorbic acid
(Harwood Academic Publishers GmbH, 1999)
An oxidative detoxification of sulfite, which originates from sulfur dioxide taken up into a leaf, has not yet been fully understood. In this study, we discuss that redox reactions between sulfite and H2O2 have an important ...
