Ultrastructure of Epicuticular Wax in Canola
U ltrastructure of the epicuticular wax of four commercially grown Canadian cultivars of canola (Brassica campestris cvs. Tobin and Candle, B. napus cvs. Altex and W estar) was investigated. Freeze-drying and air-drying methods of specimen preparation for scanning electron microscopy were compared. The freeze-drying method resulted in disruption and possible washing away of wax crystals, wherea...
متن کاملEpicuticular 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 ...
متن کاملEpicuticular Wax Alkanes of Scutellaria Lateriflora L. Leaves
The dried aerial parts of scutellaria lateriflora L. (family Labiatae), have been used for many years as a domestic remedy for epilepsy, hysteria, and nervous tension states. Although several phytochemical investigations have been made regarding the constituents present in this species (i. e. flavonoids, iridoids), none has been recorded concerning the cuticular wax. Using thin-layer chroma...
متن کاملInhibition of epicuticular wax deposition on cabbage by ethofumesate.
The weight of epicuticular wax on the surface of cabbage (Brassica oleracea var. Capitata ;Market Prize') leaves was reduced by soil treatments of ethofumesate (2-ethoxy-2,3-dihydro-3,3-dimethyl-5-benzofuranyl methanesulfonate) and EPTC (S-ethyl dipropylthiocarbamate). Separation of epicuticular wax into major components by gas-liquid chromatography indicated that ethofumesate decreased the dep...
متن کاملAnswering a four decade-old question on epicuticular wax biosynthesis.
In this issue of Journal of Experimental Botany (pages 2715–2730) Schneider et al. report the identity of three genes from barley described in the 1970s as important for the synthesis of β-diketone cuticular waxes, thereby revealing a novel polyketide synthase pathway responsible for their production. It is a perfect example of how modern sequencing technologies can resolve age-old questions on...
