Abstract excerpt

Abscisic acid (ABA) is a phytohormone that is necessary for stress adaptation. Recent studies have reported that attenuated levels of ABA improved grain yield and seedling growth under low temperature in cereals. To improve plant growth under low temperature, we attempted to generate ABA-insensitive transgenic rice by expressing a clade A type 2C protein phosphatase (OsPP2C), OsABIL2, with or without the mutation...
