An embryo culture method overcomes the lengthy dormancy requirement of Taxus L. spp. (yew) seeds. When zygotic embryos excised from mature T. brevifolia L. seeds were cultured in darkness for 4 weeks on one of three basal salt media (B5, Litvay, and Murashige and Skoog), radicle emergence and seedling development was highest on B5 basal salt medium. After 1 to 2 weeks on B5 basal salt medium, s...
BACKGROUND Illumina second generation sequencing is now an efficient route for generating enormous sequence collections that represent expressed genes and quantitate expression level. Taxus is a world-wide endangered gymnosperm genus and forms an important anti-cancer medicinal resource, but the large and complex genomes of Taxus have hindered the development of genomic resources. The research ...
In Germany, four different drug eluting stents (DES) systems are currently commercially available. Whereas sirolimus has been clinically tested in only a single type of stent with a single type of coating in only a single dose, paclitaxel has been tested on various stent designs, in various dose densities, and in various release formulations with or without a polymer carrier. Therefore, the que...
هدف تعیین پراکنش سرخدار معمولی و ارزیابی تنوع زیستی رستنی های چوبی رویشگاههای آن در جنگلهای گیلان است. بدین منظور یک قطعه نمونه به شکل لوزی و به مساحت نیم هکتار در هررویشگاه بطور انتخابی پیاده شد. در هر قطعه نمونه‘ نوع گونه ها ی چوبی وفراوانی آنها بررسی گردید. داده ها ی برداشت شده از هر رویشگاه بطور جداگانه وارد کامپیوتر شد. برای ارزیابی شاخص های تنوع زیستی (شاخص سیمپسون‘ تابع شانون-وینر و شاخ...
The title compound, C(10)H(14)O(2), was isolated from the chloro-form extract of Taxus wallichiana Zucc. In the crystal, mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds, forming sheets parallel to (100). There are weak inter-molecular C-H⋯π inter-actions between the sheets.
Taxol (paclitaxel) a diterpenoid is one of the most effective anticancer drugs identified. Biosynthesis of taxol was considered restricted to the Taxus genera until Stierle et al. discovered that an endophytic fungus isolated from Taxus brevifolia could independently synthesize taxol. Little is known about the mechanism of taxol biosynthesis in microbes, but it has been speculated that its bios...
Background: Paclitaxel (TaxolTM) is an important anticancer drug with a unique mode of action. The biosynthesis of paclitaxel had been considered restricted to the Taxus species until it was discovered in Taxomyces andreanae, an endophytic fungus of T. brevifolia. Subsequently, paclitaxel was found in hazel (Corylus avellana L.) and in several other endophytic fungi. The distribution of paclita...
