Segregation of Hydroxycinnamic Acid Esters Mediating Sweetpotato Weevil Resistance in Storage Roots of Sweetpotato
Resistance to sweetpotato weevils (Cylas spp.) has been identified in several sweetpotato (Ipomoea batatas) landraces from East Africa and shown to be conferred by hydroxycinnamic acids that occur on the surface of storage roots. The segregation of resistance in this crop is unknown and could be monitored using these chemical traits as markers for resistance in F1 offspring from breeding progra...
متن کاملHigh Population Density and Egg Cannibalism Reduces the Efficiency of Mass-rearing in Euscepes Postfasciatus (coleoptera: Curculionidae)
The West Indian sweetpotato weevil Euscepes postfasciatus (Fairmaire) (Coleoptera: Curculionidae) is a major pest of sweetpotato Ipomoea batatas (L.) Lam (Solanales: Convolvulaceae) in some countries. In order to improve mass-rearing for an eradication program employing the sterile insect technique (SIT), optimal population density of E. postfasciatus in an artificial diet was examined. Six pop...
متن کاملMetabolic 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 کاملSCOF-1-expressing transgenic sweetpotato plants show enhanced tolerance to low-temperature stress.
Low-temperature stress represents one of the principal limitations affecting the distribution and productivity of many plant species, including crops such as sweetpotato. Transgenic sweetpotato (Ipomoea batatas L. cv. Yulmi) plants expressing the soybean cold-inducible zinc finger protein (SCOF-1) under control of an oxidative stress-inducible peroxidase (SWPA2) promoter (referred to as SF plan...
