PLANT COLD RESISTANCE-ENHANCING METHOD USING ABSCISIC ACID-INSENSITIVE GENE

摘要

The present invention provides for a new cold resistance enhancement method of rice. A substitution of 183 th glycine asparagine PP2C gene which leads to abscisic acid insensitive (clade A protein phosphatase type 2C gene), or, mutations with a substitution of 315 th tryptophan alanine the type PP2C gene, including the introduction of rice, how to strengthen the cold stretch and booting stage chilling tolerance Kararanaru cold tolerance of rice, and is thereby chilling tolerance obtained enhanced rice.BACKGROUND
