Cryopreservation of Alkaloid-Producing Cell Cultures of Periwinkle (Catharanthus roseus).
A procedure for cryogenic storage of alkaloid producing cell lines of periwinkle, Catharanthus roseus (L.) G. Don., has been developed. The procedure differs from established cryopreservation protocols in several aspects. Specifically, 4-day-old suspension subcultures of three cell lines were precultured in nutrient media supplemented with 1 molar sorbitol for 6 to 20 hours. The cells were then...
متن کاملPhysiological Response of Periwinkle Plants (Catharanthus roseus L.) to Tryptophan and Putrescine
A pot experiment was conducted in the screen of the National Research Centre during two successive seasons to study the response of periwinkle plants to foliar spray with tryptophan or putrescine at the concentrations 10 M, 10 M or 10 M. The obtained data indicated that exogenous application of tryptophan or putrescine on periwinkle transplants considerably increased plant growth at successive ...
متن کاملAbiotic and biotic elicitors’ effects on secondary metabolites biosynthesis of periwinkle (Catharanthus roseus (Linn.) G. Don)
Based on recent statistical survey, the cancer is the third important factor in Iran mortality. Vinblastine and vincristine alkaloids are dominantly biosynthesized in the aerial parts of periwinkle, broadly applied for cancer treatment. Therefore, over production of these alkaloids by using the biotechnological approaches is inevitable. Since the terpenoid indole alkaloids (TIAS) biosynthesis p...
متن کاملNatural infection of Viola cornuta (Violaceae) with Cucumber mosaic virus, subgroup I.
Plants of Viola cornuta displaying typical virus symptoms were observed during spring 2003 in a plant nursery in Córdoba, central Argentina. Electron microscopic examinations of symptomatic leaf samples revealed the presence of isometric virus-like particles about 30 nm in diameter. Subsequent serological analysis allowed the identification of the pathogen as a subgroup I strain of Cucumber mos...
