Answering 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...
متن کاملEquisetum species show uniform epicuticular wax structures but diverse composition patterns
BACKGROUND AND AIMS Only few data on the epicuticular waxes (EWs) of horsetails are available. This contribution therefore focuses on the wax micromorphology and chemical composition of Equisetum species of the subgenera Equisetum and Hippochaete. METHODOLOGY Distribution patterns and structural details of EW on the shoots were studied by scanning electron microscopy. After extraction with ch...
متن کاملUltrastructure 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 کاملCOMPARISON OF EPICUTICULAR WAX ON NEEDLES AND STEMS OF Pinus eldarica WITH ITS TWO NATURALLY GENERATED FORMS
Plant cuticles are covered by epicuticular waxes with considerable ultrastructural and chemical diversity and have great systematic significance. Pinus elderica is a rare pine found naturally only in desert environment southeast of Tbilisi (Georgia). This tree have been probably introduced to Iran about 800 years ago and gradually altered in both shape and size in Nashtifan-Khaf, and changed in...
متن کاملTaxonomic significance of the epicuticular wax composition in species of the genus Clusia from Panama
We attempted to separate species of the genus Clusia according to the concentration of linear alkanes (C25 and C35), and the presence and diversity of terpenes in epicuticular wax extracts. We collected leaves of 15 Clusia species growing in mountain forests of Panama (Cerro Jefe 1007 m and Altos de Campana 800 m a.s.l.) and from cultivated plants at two lowland sites. Leaf surfaces were washed...
