Epicuticular wax of Eragrostis curvula
Phytochemistry, 1982Abstract Epicuticular wax of Eragrostis curvula contains hydrocarbons (6%), esters (13%), acids (3%), alkanols (4%), tritriacontane-12,14-dione (47%), 5(S)-5-hydroxytritriacontane-12,14-dione (14%) as major components. The esters consist of triterpenol esters (42%) as well as alkanol esters. The free alkanols consist principally Of C16C32 components,

Epicuticular waxes of two sorghum varieties
Phytochemistry, 1978Abstract The epicuticular waxes of the two sorghum varieties Alliance A and SD 102 have been analyzed, after separation of the leaf blades from the sheaths. The major constituents were found to be free fatty acids but small amounts of esters, aldehydes, alcohols, n -alkanes and sterols were also detected. The typical chain lengths of aldehydes, free

Micromorphology of epicuticular waxes in Centrosperms
Plant Systematics and Evolution, 1988Epidermal surfaces of about 500 species from some 250 genera of centrospermous families plus some possibly related families were examined by scanning electron microscopy. The micromorphology of their epicuticular waxes is described under taxonomic aspects. In general, Centrosperms tend to develop wax platelets on their cuticle.

The maize epicuticular wax layer provides UV protection
Functional Plant Biology, 2003As surface ultraviolet-B (UV-B) radiation levels increase due to the decline in the protective stratospheric ozone layer, ultraviolet radiation sunscreens will become more important for all plant species that grow in sunlight. Epicuticular waxes, which cover the aerial portions of all terrestrial plants, are ideally located to be sunscreens.

Ultrastructure and origin of epicuticular wax tubes
Journal of Ultrastructure Research, 1974Coiled wax ribbons have been found intermingled among the long, thin tubes characteristic of some barley and wheat cuticles. An analysis of the structure of these wax ribbons and their relationship to the tubes has led to the following hypothesis to explain the origin of the broad spectrum of observed epicuticular wax structures.

Epicuticular wax composition of some European Sedum species
Phytochemistry, 1994Epicuticular waxes from 30 species of Sedum and 2 species of Sempervivoideae, i.e. Aeonium spathulatum and Sempervivum nevadense, have been analysed by GC and GC-MS. The Sedum taxa examined were S. acre, S. album, S. series Alpestria (13 species), S. anglicum, S. brevifolium, S. litoreum, S. lydium, S.

Triterpenoids in Epicuticular Waxes
1989All aerial organs of higher plants are covered primarily with a thin continuous wax layer. These surface or epicuticular waxes consist of a very complex mixture of different components. In most cases these very long chained lipids are found in form of homologous series.

Evidence for Surfactant Solubilization of Plant Epicuticular Wax
Journal of Agricultural and Food Chemistry, 2001The solubilization of isolated, reconstituted tomato (Lycopersicon esculentum Mill.) fruit and broccoli (Brassica oleracaea var. botrytis L.) leaf epicuticular waxes (ECW) by nonionic octylphenoxypolyethoxy ethanol surfactant (Triton X-100) was demonstrated in a model system by TLC and fluorescence analysis using pyrene as a fluorescent probe.

Epicuticular wax variation in ecotypes of Arabidopsis thaliana
Phytochemistry, 1997Quantification of the epicuticular wax from the stems of 40 ecotypes of Arabidopsis thaliana showed a two-fold range in total wax load that was not correlated to known abiotic characteristics of the ecotype's origin of collection. Chemical analysis of these ecotypes revealed similar epicuticular wax profiles for all ecotypes except CT-1.

Molecular genetics of epicuticular wax biosynthesis
Trends in Plant Science, 1996The epicuticular wax (EW) layer that coats the outer surface of plants is composed of a variety of long chain length hydrocarbons. Genetic studies indicate that a very large number of genes are involved in wax production. However, the pathway(s) by which the waxes are synthesized and deposited onto the plant surface remain elusive.
