فاکتورهای زیادی در تشکیل کالوس و افزایش در میزان کالوس در شرایط درون شیشه ای موثرند که نوع ریزنمونه، نوع محیط کشت، نوع هورمون و عوامل محیطی از موارد بسیار مهم می باشد. سرخدار (taxus) یکی از سوزنی برگان بومی و با ارزش جنگل های شمال بوده که قسمت های متفاوت آن منبع اولیه تولید داروی ضد سرطان تاکسول است که دارای کاربرد وسیعی در درمان بیماری های سرطان سینه، رحم، تخمدان و ... می باشد. هدف از انجام پژ...
male and female leaves and fruits of eleven different taxons of iranian conifers (cupressus sempervirens var. horizontalis, c. sempervirens var. sempervirens, c. sempervirens cv. cereifeormis, juniperus communis subsp. hemisphaerica, j. excelsa subsp. excelsa, j. excelsa subsp. polycarpos, j. foetidissima, j. oblonga, j. sabina, platycladus orientalis and taxus baccata) were collected from diff...
Phytochemical investigations of Taxus baccata L. by successive chromatographic methods resulted in the isolation of the lignans lariciresinol (1), taxiresinol (2), 3'-demethylisolariciresinol-9'-hydroxyisopropylether (3), isolariciresinol (4), and 3-demethylisolariciresinol (5) as well as taxoids. Compounds 1-5 were evaluated for their acetylcholinesterase (AChE), butyrylcholinesterase (BChE), ...
The present investigation was undertaken to evaluate the bronchodilating effect and bronchial hyperreactivity of alcoholic extract of Taxus baccata Linn. (AET) leaves in experimental animals. Bronchodilator activity of AET was studied on the histamine and acetylcholine aerosol induced bronchospasm in guinea pigs and bronchial hyperreactivity was studied on bronchoalveolar lavage fluid (BALF) in...
Identification of efficient key enzymes in biosynthesis pathway and optimization of the fitness between functional modules and chassis are important for improving the production of target compounds. In this study, the taxadiene biosynthesis pathway was firstly constructed in yeast by transforming ts gene and overexpressing erg20 and thmgr. Then, the catalytic capabilities of six different geran...
Abstract Key message Taxus baccata remnants established recently tend to contribute less the species’ overall genetic variation than historical populations because they are subjected a greater impact of founder effect and isolation. As tree trunk perimeter is rough indicator in population, this measure should be considered conservation programs. Context Genetic within (L.) not associated with c...
