Fructan biosynthesis in transgenic plants.
Data from plants transformed to accumulate fructan are assessed in the context of natural concentrations of reserve carbohydrates and natural fluxes of carbon in primary metabolism: Transgenic fructan accumulation is universally reported as an instantaneous endpoint concentration. In exceptional cases, concentrations of 60-160 mg g(-1) fresh mass were reported and compare favourably with natura...
متن کاملEffects of different carbohydrate sources on fructan metabolism in plants of Chrysolaena obovata grown in vitro
Chrysolaena obovata (Less.) Dematt., previously named Vernonia herbacea, is an Asteraceae native to the Cerrado which accumulates about 80% of the rhizophore dry mass as inulin-type fructans. Considering its high inulin production and the wide application of fructans, a protocol for C. obovata in vitro culture was recently established. Carbohydrates are essential for in vitro growth and develop...
متن کاملFructan metabolism and changes in fructan composition during cold acclimation in perennial ryegrass
Perennial ryegrass (Lolium perenne L.) produces high levels of fructans as a mixture of oligosaccharides and polysaccharides with different degrees of polymerization (DP). The present study describes the analysis of the compositional changes in the full spectrum of fructans, fructan distribution between above ground biomass (top) and the roots, and the transcription of candidate genes involved ...
متن کاملFructan as a New Carbohydrate Sink in Transgenic Potato Plants.
Fructans are polyfructose molecules that function as nonstructural storage carbohydrates in several plant species that are important crops. We have been studying plants for their ability to synthesize and degrade fructans to determine if this ability is advantageous. We have also been analyzing the ability to synthesize fructan in relation to other nonstructural carbohydrate storage forms like ...
متن کاملThe relationship of fructan to abiotic stress tolerance in plants
Fructan has long been recognized as a crucial component of drought and freeze protection in plants but the relationship is controversial and many studies have shown contradictory correlations between fructan and resistance to stress. Much of the early research considered how hexose sugars from fructan hydrolysis affected the chemical potential of water. As model membrane systems became availabl...
