Epicuticular wax crystals of Wollemia nobilis: morphology and chemical composition.
BACKGROUND AND AIMS The morphology of the epicuticular leaf waxes of Wollemia nobilis (Araucariaceae) was studied with special emphasis on the relationship between the microstructure of epicuticular wax crystals and their chemical composition. Wollemia nobilis is a unique coniferous tree of the family Araucariaceae and is of very high scientific value as it is the sole living representative of ...

15 صفحه اولChemical composition of the epicuticular and intracuticular wax layers on adaxial sides of Rosa canina leaves.
BACKGROUND AND AIMS The waxy cuticle is the first point of contact for many herbivorous and pathogenic organisms on rose plants. Previous studies have reported the average composition of the combined wax extract from both sides of rose leaves. Recently, the compositions of the waxes on the adaxial and abaxial surfaces of Rosa canina leaves were determined separately. In this paper, a first repo...
متن کاملChemical composition of preen wax reflects major histocompatibility complex similarity in songbirds.
In jawed vertebrates, genes of the major histocompatibility complex (MHC) play a key role in immunity by encoding cell-surface proteins that recognize and bind non-self antigens. High variability at MHC suggests that these loci may also function in social signalling such as mate choice and kin recognition. This requires that MHC genotype covaries with some perceptible phenotypic trait. In mamma...
متن کاملChemical composition of the Prunus laurocerasus leaf surface. Dynamic changes of the epicuticular wax film during leaf development.
The seasonal development of adaxial Prunus laurocerasus leaf surfaces was studied using newly developed methods for the mechanical removal of epicuticular waxes. During epidermal cell expansion, more than 50 microg leaf(-1) of alkyl acetates accumulated within 10 d, forming an epicuticular wax film approximately 30 nm thick. Then, alcohols dominated for 18 d of leaf development, before alkanes ...
