Sesquiterpene lactones in a hairy root culture of Cichorium intybus.
A transformed root culture of Cichorium intybus L. (Asteraceae) was found to produce sesquiterpene lactones of guaiane and germacrane type. Lactucopicrin, 8-desoxylactucin and three sesquiterpene lactone glycosides: crepidiaside B, sonchuside A and ixerisoside D were isolated from the roots. The yield of 8-desoxylactucin reached 0.03 g l(-1) at the early stationary phase of the culture.
متن کاملGrowth, fructan yield, and quality of chicory (Cichorium intybus L.) as related to photosynthetic capacity, harvest time, and water regime.
Fructans are polymers that are widely used in several industrial applications. In the last few years they have received increasing interest because of their positive effects on health. At present, fructans are mostly supplied by chicory, which is only grown and processed in The Netherlands, France, and Belgium. It would therefore be an attractive concept to expand its cultivation to the souther...
متن کاملSecondary Metabolite Contents and Antioxidant Enzyme Activities of Cichorium intybus Hairy Roots in Response to Zinc
Hairy root systems are formed by transforming plant tissues with the “natural genetic engineer” Agrobacterium rhizogenes. In most plants such as Cichorium intybus L., hairy root cultures have proven to be an efficient system for secondary metabolites production. The effect of Zinc (ZnSO4), a heavy metal, was investigated at different concentrations (0, 1, 5 and 10 mM) on some secondary metaboli...
متن کاملLinking Expression of Fructan Active Enzymes, Cell Wall Invertases and Sucrose Transporters with Fructan Profiles in Growing Taproot of Chicory (Cichorium intybus): Impact of Hormonal and Environmental Cues
In chicory taproot, the inulin-type fructans serve as carbohydrate reserve. Inulin metabolism is mediated by fructan active enzymes (FAZYs): sucrose:sucrose 1-fructosyltransferase (1-SST; fructan synthesis), fructan:fructan-1-fructosyltransferase (1-FFT; fructan synthesis and degradation), and fructan 1-exohydrolases (1-FEH1/2a/2b; fructan degradation). In developing taproot, fructan synthesis ...
متن کاملOptimization of hairy root induction in chicory (Cichorium intybus L.) and effects of nanoparticles on secondary metabolites accumulation
Hairy root culture is an effective method to produce secondary metabolites. In fact, hairy roots are genetically and biologically stable and also they are able to produce metabolites without hormones. Chicory (Cichorium intybus L.) is one of the most important medicinal plants with valuable medicinal compounds. In this research, hairy roots were induced by different Agrobacterium rhizogenes str...
