Metabolic engineering of carotenoids in transgenic sweetpotato
Sweetpotato [Ipomoea batatas (L.) Lam], which contains high levels of antioxidants such as ascorbate and carotenoids in its storage root, is one of the healthiest foods, as well as one of the best starch crops for growth on marginal lands. In plants, carotenoid pigments are involved in light harvesting for photosynthesis and are also essential for photo-protection against excess light. As dieta...
متن کاملEnhanced accumulation of carotenoids in sweetpotato plants overexpressing IbOr-Ins gene in purple-fleshed sweetpotato cultivar.
Sweetpotato [Ipomoea batatas (L.) Lam] is an important root crop that produces low molecular weight antioxidants such as carotenoids and anthocyanin. The sweetpotato orange (IbOr) protein is involved in the accumulation of carotenoids. To increase the levels of carotenoids in the storage roots of sweetpotato, we generated transgenic sweetpotato plants overexpressing IbOr-Ins under the control o...
متن کاملEffect of drying and storage on the degradation of total carotenoids in orange-fleshed sweetpotato cultivars.
BACKGROUND Orange-fleshed sweetpotato (OFSP) can be used to tackle vitamin A deficiency, a major public health problem in most developing countries. In East Africa, common ways of using sweetpotato include drying and subsequent storage. The aim of the study was to investigate the impact of drying and storage on the total carotenoid retention (as an estimate of provitamin A retention) from OFSP....
متن کاملAssaying Total Carotenoids in Flours of Corn and Sweetpotato by Laser Photoacoustic Spectroscopy
This study describes the application of the laser photoacoustic spectroscopy (PAS) for quantification of total carotenoids (TC) in corn flours and sweetpotato flours. Overall, thirty-three different corn flours and nine sweetpotato flours were investigated. All PAS measurements were performed at room temperature using 488-nm argon laser radiation for excitation and mechanical modulation of 9 an...
متن کاملImprovement for agronomically important traits by gene engineering in sweetpotato
Sweetpotato is the seventh most important food crop in the world. It is mainly used for human food, animal feed, and for manufacturing starch and alcohol. This crop, a highly heterozygous, generally self-incompatible, outcrossing polyploidy, poses numerous challenges for the conventional breeding. Its productivity and quality are often limited by abiotic and biotic stresses. Gene engineering ha...
