Enhanced tolerance to low temperature stress of transgenic sweetpotato plants expressing a cold-inducible zinc finger protein,SCOF-1

摘要：

Low temperature stress is one of the principal limitations affecting plant species distribution and crop productivity including sweetpotato. Transgenic sweetpotato (Ipomoea batatas L. cv. Yulmi) plants expressing soybean cold-inducible zinc finger protein, SCOF-1 under the control of an oxidative stress-inducible peroxidase (SWPA2) promoter (referred to as SF plants) were developed and evaluated for enhanced tolerance of SF plants under low temperature conditions. Following 413 treatment of SF plants, SCOF-1 expression positively correlated with tolerance to low-temperature treatment. SF plants treated with low-temperature stress exhibited less of a reduction in photosynthetic activity and lipid per-oxidation levels than non-transgenic plants. This study has shown that low-temperature stress in sweetpotato can be efficiently modulated by overexpression of SCOF-1.
