Since the recent discovery of taxol and other taxanes in Corylus avellana, this plant species has attracted interest as a potential new source of these compounds. However, its low taxane content in comparison with Taxus spp. has restricted research to analytical identification or global quantitation. A feasible and sensitive method based on liquid chromatography-tandem mass spectrometry using a...
background: sustainable and commercial production of taxol as an anti cancer drug is a critical point to its clinical application. nowadays, hazel because of rapid growth and wide range distribution is considered as an alternative source of taxol. objective: to increase taxol production the cdna encoding 3-hydroxy-3-methylglutaryl-coa reductase (hmgr) from iranian hazel (genebank accession numb...
Effects of IBA and Mycorrhizal fungi inoculation on rooting growth the semi- hardwood cuttings Corylus avellana L.
مقدمه: فندق corylus avellana یکی از گونه های متعلق به جنس corylus است. قسمتهای مختلف این گیاه حاوی انواع مهمی از متابولیتهای دارویی با اثرات ضد سرطانی و ضد میکروبی بسیار ارزشمند میباشد. هدف: تحقیق حاضر با هدف ارزیابی توانایی تولید تاکسول و همچنین بهینه سازی کالزایی و باززایی فندق از ریزنمونههای کوتیلدونی بذر انجام شد. روش بررسی: قطعات کوتیلدون برای القای کالوس در محیط کشت موراشیگ و اسکوک (m...
The new genus Corylomyces, isolated from the surface of a hazelnut (Corylus avellana) in the French Pyrenees, is described, illustrated and compared with morphologically similar taxa. It is characterised by tomentose, ostiolate ascomata possessing long necks composed of erect to sinuose hairs, and one- or two-celled, opaque, lunate to reniform ascospores. Analyses of the SSU and LSU fragments r...
The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...
Leaf water potentials measured by in situ psychrometry were compared with leaf water potentials measured by the pressure chamber technique at various values of water potential in Helianthus annuus, Helianthus nuttallii, Vigna unguiculata, Nerium oleander, Pistacia vera, and Corylus avellana. In V. unguiculata, the leaf water potentials measured by the in situ psychrometer oscillated at the same...
