Fructan 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 کاملFructan 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 کاملFunction of phytochrome A in potato plants as revealed through the study of transgenic plants.
We have generated transgenic potato plants (Solanum tuberosum) containing the potato phytochrome protein encoded by the PHYA gene cDNA (phyA) in sense or antisense orientation under the control of the 35S cauliflower mosaic virus promoter. Plants with increased and decreased phyA levels were analyzed. When grown under white light, development and growth of sprouts and plants were barely disting...
متن کاملFructan: more than a reserve carbohydrate?
Most plants store starch or Suc as reserve carbohydrates, but about 15% of all flowering plant species store fructans, which are linear and branched polymers of Fru. Among the plants that store fructans are many of significant economic importance, such as cereals (e.g. barley, wheat, and oat), vegetables (e.g. chicory, onion, and lettuce), ornamentals (e.g. dahlia and tulip), and forage grasses...
متن کاملEnhanced salt stress tolerance in transgenic potato plants expressing IbMYB1, a sweet potato transcription factor.
IbMYB1, a transcription factor (TF) for R2R3-type MYB TFs, is a key regulator of anthocyanin biosynthesis during storage of sweet potatoes. Anthocyanins provide important antioxidants of nutritional value to humans, and also protect plants from oxidative stress. This study aimed to increase transgenic potatoes' (Solanum tuberosum cv. LongShu No.3) tolerance to environmental stress and enhance t...
