Cuticular waxes play a pivotal role in limiting transpirational water loss across the plant surface. The correlation between chemical composition of cuticular and their function as transpiration barrier is still unclear. In present study, intact tomato fruits (Lycopersicon esculentum) are used, due to astomatous surface, novel integrative approach investigate this composition– relationship: wax amounts compositions were manipulated before measuring unbiased transpiration. First, successive...
Grape (Vitis vinifera cv Silvaner) vine plants were cultivated under shaded conditions in the absence of ultraviolet (UV) radiation a greenhouse, and subsequently placed outdoors three different light regimes for 7 d. Different produced by filters transmitting natural radiation, or screening out UV-B (280-315 nm), UV-A (315-400 nm) spectral range. During exposure, synthesis UV-screening phenolics leaves was quantified using HPLC: All treatments increased concentrations hydroxycinnamic acids...
Cuticular waxes play a pivotal role in limiting transpirational water loss across the primary plant surface. The astomatous fruits of tomato (Lycopersicon esculentum) 'MicroTom' and its lecer6 mutant, defective β-ketoacyl-coenzyme A synthase, which is involved very-long-chain fatty acid elongation, were analyzed with respect to cuticular wax load composition. developmental course fruit ripening was followed. Both wild type mutant showed similar patterns quantitative accumulation, although...
ABSTRACT The composition and spatial arrangement of cuticular waxes on the leaves Prunus laurocerasus were investigated. In wax mixture, triterpenoids ursolic acid oleanolic as well alkanes, fatty acids, aldehydes, primary alcohols alcohol acetates identified. surface extraction upper lower leaf surfaces yielded 280 mg m − 2 830 , respectively. Protocols for mechanical removal from outermost layers cuticle devised evaluated. With most selective these methods, 130 could be removed adaxial...

ABSTRACT Transmittance spectra of isolated plant cuticles were measured in the wavelength range from 270 to 600 nm. The enzymatically leaves 27 species (26 evergreen or deciduous woody, one succulent herbaceous) and four fruits. With exception subtropical tropical all plants cultivated field. studied strongly attenuated ultraviolet (UV) radiation at wavelengths < 400 nm while they practically translucent visible range. Relatively broad transmittance minima occurred 280 320 (UV‐B)....
Abstract Plant cuticles sorb large amounts of hexadecanoic acid, octadecanoic acid and other lipophilic compounds (not identified) when incubated in cell slurries obtained by enzymatically digesting leaves or fruits. These extraneous substances cannot be removed completely selectively after cuticle isolation, nor is it possible to prevent sorption optimizing isolation procedures. It is, therefore, impossible estimate composition intracuticular soluble lipids using isolated cuticles, as has...
Plant cuticular waxes play a crucial role in limiting nonstomatal water loss. The goal of this study was to localize the transpiration barrier within layered structure cuticles eight selected plant species and put its physiological function into context with chemical composition intracuticular epicuticular wax layers. Four (Tetrastigma voinierianum, Oreopanax guatemalensis, Monstera deliciosa, Schefflera elegantissima) contained only very-long-chain fatty acid (VLCFA) derivatives such as...
Abstract Maintaining the integrity of cuticular transpiration barrier even at elevated temperatures is vital importance especially for hot-desert plants. Currently, temperature dependence leaf water permeability and its relationship with chemistry cuticles are not known a single desert plant. This study investigates whether (i) plant lower than that species from non-desert habitats, (ii) temperature-dependent increase less pronounced in those (iii) susceptibility to high related amounts or...
The efficacy of the cuticular transpiration barrier and its resistance to elevated temperatures are significantly higher in a typical water-saver than water-spender plant growing hot desert.
The water permeability of the leaves three deciduous plants (Acer campestre, Fagus sylvatica, Quercus petraea) and two evergreen (Hedera helix, Ilex aquifolium) was analysed in order to assess its role as a mechanism drought resistance. Cuticular permeances were determined by measurement loss through adaxial, astomatous leaf surfaces. Minimum conductances after complete stomatal closure obtained drying curves. comparison permeabilities with these experimental systems revealed good agreement...
Abstract In the cuticular wax mixtures from leaves of pea (Pisum sativum) cv Avanta, Lincoln, and Maiperle, more than 70 individual compounds were identified. The adaxial was characterized by very high amounts primary alcohols (71%), while abaxial consisted mainly alkanes (73%). An aqueous adhesive gum arabic employed to selectively sample epicuticular layer on hence analyze composition crystals exposed at outermost surface leaves. found contain 74% 83% total surfaces, respectively....
The permeability of astomatous leaf cuticular membranes Hedera helix L. was measured for uncharged hydrophilic (octanol/water partition coefficient log K(O/W) < or =0) and lipophilic compounds (log >0). set included plant protection agents, carbohydrates, the volatile water ethanol. Plotting mobility model versus molar volume resulted in a clear differentiation between pathway. size selectivity pathway described by free theory. pronounced tortuosity diffusional path caused waxes, leading to...
