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 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 کاملMathematical model of fructan biosynthesis and polymer length distribution in plants
BACKGROUND AND AIMS There are many unresolved issues concerning the biochemistry of fructan biosynthesis. The aim of this paper is to address some of these by means of modelling mathematically the biochemical processes. METHODS A model has been constructed for the step-by-step synthesis of fructan polymers. This is run until a steady state is achieved for which a polymer distribution is predi...
متن کاملRe-Programming Photosynthetic Cells of Perennial Ryegrass (Lolium perenne L) for Fructan Biosynthesis through Transgenic Expression of Fructan Biosynthetic Genes under the Control of Photosynthetic Promoters
High molecular weight fructans are the main class of water-soluble carbohydrate used for energy storage in many temperate grass species including perennial ryegrass (Lolium perenne L.). As well as being important readily mobilisable energy reserves for the plant, fructans are also involved in stress tolerance. Fructans are also readily digested by grazing ruminants and hence are a valuable sour...
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...
